MINUTES OF THE NAPIER AMATEUR RADIO CLUB

Meeting on Wednesday 4 July 2018 at the Clubrooms 123 Latham Street

Chair: Dave ZL2MQ, the meeting started at 7:30 pm.

Present: Dave ZL2DW, Wally ZL2MO, Paul ZL2HB, Blue ZL3TT, Mike ZL2MY, Peter ZL2CD, Revel ZL2SS, Errol ZL2IT and Karl ZL1TJ.

Apologies: ZL2XC, ZL2ST and ZL2VM.

Minutes of previous meeting: Read and confirmed to be correct: ZL3TT, ZL2HB.

Arising: Dave ZL2DW: the proposed NZART public liability insurance for members will now also apply to branches with charitable / non profit status according to Peter Mulhare ZL2IK.

Also: the on line sale of Baofeng hand-held radios was discussed at the last Branch 13 meeting.

It was decided to spread the information via the reflectors and pass names etc. onto the Radio Inspectorate. The Radio Inspector responsible for the area is reported to visit Hawke’s Bay soon to investigate the matter further.

Dave ZL2MQ: the two remaining SWR Power meters have now been sold. Trade-me fees are now exorbitant.

Correspondence: various email correspondence: Peter Mulhare re: NZART insurance, non profits are excluded. Internal emails regarding new Bank and members financial status.

Finance: Treasurers report attached.

General Business: Errol ZL2IT questioned Dave 2DW regarding the proposed AREC communications trailer (see minutes 6 June). The status and usage of the present ageing caravan was discussed. The consensus was that the proposed trailer is a viable concept. It will be supported by Branch 13, support from Branch 25 will also be needed.

Dave 2DW mentioned the annual Branch 13 junk and scrap metal collection is now ‘on’ and the associated auction of ‘The Good Stuff’ is to take place at the next Branch 13 meeting, July 25th.

The winner’s trophy for the Branch 13 home brew contest was presented to Errol ZL2IT.

Dave 2MQ asked for information about ‘The Napier Branch Verification Cup’ (NZRA DX). First presented in 1933 it appears not to have been contested after 1938. There are a few other ancient trophies that may be of interest and need to be identified.

The meeting closed at 8pm and was followed by an interesting ‘Show and tell’ session.

Mike ZL2MY presented a simple but clever central hub for a VHF / UHF ground plane antenna. Resonant frequency can be changed quickly by exchanging rods.

Dave ZL2DW presented a much more satisfactory way of utilising an (automatic) antenna tuner. It is mounted just below the (dipole) antenna balun in a weather proof enclosure. An inductor / capacitor network is used to feed the necessary 12V dc up the coax cable to feed the tuner.

Errol ZL2IT presented his E-Field Probe Active antenna. A small device made of copper laminate with a J-Fet transistor. It works on the electrostatic dimension of radio waves and has a very wide pass band. In Errol’s case is used to receive 475 KHz. Also, similar to Dave’s, a DC into coax injector device to go with the antenna.

Errol also presented a DDS oscillator, high stability, to take the place of a number of crystals in an older radio. The device is paired with a Picaxe micro processor to provide the 2 bit parameter input and read the 14 bit output using Hexadecimal coding. High Tech. Amateur Radio in the 21st century.

Club Meeting 6 June 2018

MINUTES OF THE NAPIER AMATEUR RADIO CLUB

Meeting on Wednesday 6 June 2018 at the Clubrooms 123 Latham Street

Chair: Dave ZL2MQ, the meeting started at 7:30 pm.

Present: Dave ZL2DW, Rob ZL2US, Wally ZL2MO, Paul ZL2HB, Blue ZL3TT, Mike ZL2VM, Mike ZL2MY, Stan ZL2ST, Peter ZL2CD, John ZL2VAF, Phil ZL2RO and Karl ZL1TJ.

Apologies: ZL2XC.

Minutes of previous meeting: Read and confirmed to be correct: ZL2HB, ZL2VM.

Arising: Dave ZL2DW: Conference remit voting: the first three remits were lost, the last two passed. Dave 2MQ enquired at what stage the chair replacement is. A response to Peter 2LF’s email to the scouting people has not been received. Karl to follow up.

Correspondence: various email correspondence: apology from Stu ZL2XC, Bank statements, NZART regarding remit voting and proxy, initial application for non profit status.

Finance: Dave ZL2MQ and Peter explained the Club’s switch to Kiwibank. The primary reason being the ANZ Bank’s inability to provide a dual signature online service. Consequently it is recommend the club applies for Non-profit status as the bank waves most fees for this.

Dave 2DW: tax on term deposit interest will be saved also. Karl to action.

The Club’s new Bank Account number is: 38-9019-0636026-00. Make a note!

General Business: Dave 2MQ reported on the SWR bridge project. All but two have been sold. The last two will be offered for sale on Trade-me if no further enquiries come through.

The club’s beacons have been off the air briefly, minor changes to reduce white noise and key clicks have been made. Errol ZL2IT’s QTH is close to the beacon location. He monitors signal quality regularly.

Paul ZL2HB mentioned the availability of both police band and amateur radio transceivers to anybody, mostly through the internet and direct from China. This is not new of course but the problem appears to be getting worse.

The meeting closed at 8pm.

And was followed by two talks by John ZL2VAF.

The first was about the Hawke’s Bay Knowledge Bank, a repository of historical and current information about Hawke’s Bay and it’s people. It is a community operation managed by the Hawke’s Bay Digital Archives Trust on behalf of the people of Hawke’s Bay.

Located at Stoneycroft House, 901 Omahu Road Hastings. See: www.knowledgebank.org.nz

Become a friend or member, annual fees $25.00.

John then proceeded to explain the AREC trailer project. To be purpose built and take over from the present AREC caravan which is getting older and in need of serious repairs. John explained the various purposes the trailer would be used for, it’s construction and contents and the need for contributions to finance it. While local authorities are steering away from amateur radio involvement in emergency communications there is no reason why we should not be prepared, just in case ‘The System’ falls over.

Peter ZL2LF: Offered to the club on a long term loan basis a 60MHz oscilloscope and antistatic mat. Accepted with thanks. Peter also offered to look into obtaining new chairs for the clubroom.

HB Hamfest: The venue has now been changed to the Napier Aero Club rooms, Watchman road.

A proposed programme has been sent to all members and was briefly discussed. Starting time now is 9 am. Advertising has resulted in a number of enquiries. Peter 2LF confirmed the availability of his audio system. Projector and screen to be hired (Dave 2MQ) Due to the additional cost it was proposed that the attendance fee is $20. Agreed to by all present. The final costing for the SWR – power meter kitset will be known within the next week or so.

Dave ZL2DW: at the last Bch 13 the following was discussed: 1) The possibility of an advertised ‘public’ open day, possibly held at the Napier clubrooms, possibly coinciding with a NARC open door (Sunday afternoon). To be considered at committee level. 2) A visit to the Reporoa Marine radio station, either the 3rd or 10th of March. 3) A Bch 13 organised DF (fox hunt) exercise (using Errol 2IT’s gear and ideas) on a Saturday afternoon to be decided.

Club meeting 6 December 2017

MINUTES OF THE NAPIER AMATEUR RADIO CLUB

Meeting on Wednesday 6 December 2017 at the Clubrooms 123 Latham Street

Chair: Dave ZL2MQ, the meeting started at 7:30 pm.

Present: Revell ZL2SS, Peter ZL2CD, Dave ZL2DW, Michael ZL2MY, Wally ZL2MO,

Paul ZL2HB, Blue ZL3TT, Errol ZL2IT, Stan ZL2ST, Mike ZL2VM and Karl ZL1TJ.

Apologies: ZL2XC and ZL2US.

Minutes of previous meeting: Read and confirmed to be correct: ZL2HB, ZL2MO.

Arising: Dave 2DW: both the annual combined branches end of year dinner and the ‘summer wine’ bus trip went well. The latter saw 9 participants, no one was ‘evicted or arrested’ for misbehaving.

Correspondence: various email correspondence regarding the 2018 hamfest. Advertising and seeking speakers. Requests for support from radio equipment suppliers resulted in one ‘no thank you’ and one ‘no reply’. Email from Stu 2XC, in Papua NG for the week, available for 40m QSO’s.

Finance: RSM invoice for licence fees has been paid by direct debit. Transfer of cheque signing authority from Stan to Paul has been achieved with the usual bank hassles. The Napier CC ground rent account can now be paid.

General Business:

Dave 2MQ: A second run of the pool Cue antenna kitset has been cancelled due to lack of interest.

Wally obtained quotes for the hire of spray painter, cherry picker, cost of paint and sign lettering.

Errol offered his spray painter for use by the club. Some discussion led to the conclusion that the roof, being low pitch, can be safely painted without the use of additional equipment.

Errol suggested that, considering the great job building custodian Wally has done on the interior of the clubrooms, the club could perhaps consider looking at replacing the ageing chairs. Stan explained the history of the existing chairs. To be further considered at the next committee meeting.

Karl reported briefly on the state of hamfest preparations, advertising is in place, several speakers have confirmed availability. The venue has been booked but details of catering etc. need to be finalized.

The meeting closed at 8:07 pm.

And was followed by Dave 2MQ presenting a slide show explaining the multi band, microprocessor based SWR meter he has designed and built as the club’s next project. The meter can be offered as a partially built kitset or fully built up and should, all going well, be available at the April 7th hamfest. One built up meter could be the raffle prize. Dave’s excellent presentation, showing both the versatile electronic hardware available now and also what can be done with simple programming, will fill one of the slots at the hamfest, ideally the first or second one.

Being the end of year meeting the customary liquid refreshment etc. made the evening special.

Karl ZL1TJ Secretary NARC.

MINUTES OF THE NAPIER AMATEUR RADIO CLUB

Meeting on Wednesday 1 November 2017 at the Clubrooms 123 Latham Street

Chair: Dave ZL2MQ, the meeting started at 7:30 pm.

Present: Revell ZL2SS, Peter ZL2CD, Dave ZL2DW, Wally ZL2MO, Paul ZL2HB, Blue ZL3TT, Errol ZL2IT, Stan ZL2ST, Rob ZL2US, Stu ZL2XC and Karl ZL1TJ.

Apologies: ZL2VM.

Minutes of previous meeting: Read and confirmed to be correct: ZL2MO, ZL3TT.

Arising: Dave ZL2DW: waiting to hear back from Masterton Radio Club regarding numbers for the proposed second run Pool Q 2 band antenna. Whanganui may also be interested.

Dave 2MQ: costing comes to $45 plus freight if any.

Dave 2DW: the annual Waipawa meeting and dinner was another success, about 20 attended.

Dave 2MQ: all equipment offered on Trade me was sold for fair prices, the club’s coffers benefited.

Correspondence: Accounts from Napier City Council for annual ground rental, account from Radio Spectrum Management for licence fees. Email correspondence regarding the proposed hamfest and possible presentators.

Finance: To be presented at the AGM following the monthly meeting.

General Business: Dave 2DW: The annual end of year joint branches dinner will be held at the Napier RSA restaurant 0n Saturday 24 November starting 6pm. Bookings required asap.

Also the next Branch 13 meeting will be on the 22nd and include both the AGM and the annual home brew contest. This year will also see a repeat of the popular ‘Summer wine’ bus trip and lunch. All welcome to join, talk to Dave 2DW or Rob 2US.

Revell 2SS: did an Internet search of amateur radio club buildings and signage on these in connection with proposed added signs for the NARC building. Revell printed a number of these off for us to check and get inspired and hopefully persevere with the project.

Dave 2DW opened a brief discussion on next year’s (7 April) Hamfest. Proposed to follow previous format with Friday night registration and meet up and Saturday dinner at the RSA or similar. Dave 2MQ to make firm bookings, also check out catering etc.. Paul 2HB suggested another attempt is made to find a commercial sponsor. Karl to check out. The speakers to be invited and other details will be discussed at this month’s committee meeting (21st).

Stan 2ST reported briefly on last weekends CQ worldwide CW contest.

The meeting closed at 8:05 pm.

It was followed by the AGM after which two contenders presented construction projects:

Stu ZL2XC, a microprocessor (Arduino) based device with touch screen control, communicating with the transceiver, driving two servo motors and band switch relays to automatically adjust the antenna tuner to a perfect match. The device being in the prototype stage looked vey promising and Hi Tech and we are looking forward to see the device fully operational.

Errol ZL2IT presented a truly innovative idea: a water cooled 50 MHz 250 W linear amplifier. Why water cooled? Because large heatsinks are expensive and the shed happened to yield a suitable car heater core. And just for the fun of it. Again, about 90% completed, it looks promising and we are looking forward to see the finished product.

The vote for the most innovative project went to Errol’s amplifier with a very small margin.

Karl ZL1TJ Secretary NARC.

Napier ARC meeting 4.10.17

MINUTES OF THE NAPIER AMATEUR RADIO CLUB

Meeting on Wednesday 4 October 2017 at the Clubrooms 123 Latham Street

Chair: Dave ZL2MQ, the meeting started at 7:30 pm.

Present: Revell ZL2SS, Peter ZL2CD, Dave ZL2DW, Wally ZL2MO, Paul ZL2HB, Blue ZL3TT, Errol ZL2IT, Mike ZL2VM, Stan ZL2ST, Michael ZL2MY and Karl ZL1TJ. Apologies: ZL2US.

Minutes of previous meeting: Read and confirmed to be correct: ZL2HB, ZL3TT.

Arising: Dave ZL2DW: following up on Errol’s querie about the week-end licensing course costs it has now been agreed that NZART’s reduced part year membership fees allow the cost to be reduced.

Correspondence: email exchanges regarding the possibility of DF (fox hunt) exercises (Errol 2IT) and some interest from the Masterton club in the 2014 club pool Que antenna project (Dave 2DW).

Finance: Account for $250 presented by Karl for radio equipment purchased from SWL estate.

General Business: Dave 2DW: the next Branch 13 meeting will be the annual excursion to Waipawa, dinner at Mulligan’s, all welcome and spare seats may be available. Also, the Masterton Radio Club may be interested in buying a few of our (2014) pool Q 2m/70cm kitset antennas. Are we interested? Dave 2MQ offered to do a costing for another run, Dave 2 DW to find out the numbers required. The kitset could possibly also be sold at the 2018 Hamfest.

A working bee is planned for Saturday 14 October. Jobs to do: painting of soffits and windows, repair gutters, replace outside lights, refit the Gillchrist Memorial Hall lettering and a few minor jobs. A show of hands showed adequate support.

Karl: equipment purchased from SWL estate to be sold on Trade me by Dave 2MQ to boost club funds. Club members interested can set a reserve and purchase items at that price if the is reserve is not met on Trade me. Contact Dave or Karl.

Errol’s presentation to Branch 13 of the concept of a simple offset tuning attenuator added to a handheld 2 m radio was received well. He will repeat the demonstration at the NARC Open door on Sunday 15.10 (1:30 pm). There is some interest form some members from both branches to get together and build this device to eventually be followed up by a DF ‘fox hunt’ exercise. Suggested by Dave 2DW: a Pakowai Hall BBQ after. Napier clubrooms may also be suitable?

At the September committee meeting the 3 band yagi antenna and support system was discussed. The committee, with the exception of Revell ZL2SS is not overly enthusiastic about proceeding with this, at least for the time being. It is a big job and the difficulties to make structures safe and vandal proof appear to be substantial. Dave 2MQ asked how often club member would use the equipment and out of all present only two, possibly three members made a commitment.

It was decided not to proceed for the time being.

Dave 2MQ reminded all that our next meeting will be the AGM and that nominations are now called for. In particular a new treasurer is needed as Stan 2ST is now, after many years of great service to the club, definitely resigning the position. Consider giving this a go, it is not a demanding job and support from President and Secretary is always there. Contact Dave or Karl.

Finally a request from Errol 2IT: I am restoring WW2 radio equipment, does anyone have spares, in particular valves such as 1T4, 1S5 etc..

The meeting closed at 8:25pm.

Followed by our annual quiz and (not very) sticky bun event. Questions from the NZART data bank and an interesting range of general knowledge ones kept us entertained for a while. Winners: Revell 2SS came 1st, shared 2nd and 3rd Dave 2DW and Peter 2CD. Thank you Dave 2MQ for organizing.

Karl ZL1TJ Secretary NARC.

Napier ARC Meeting 6.9.17

MINUTES OF THE NAPIER AMATEUR RADIO CLUB

Meeting on Wednesday 6 September 2017 at the Clubrooms 123 Latham Street

Chair: Dave ZL2MQ, the meeting started at 7:30 pm. Dave welcomed Peter Mulhare ZL2IK

Present: Revell ZL2SS, Peter ZL2CD, Dave ZL2DW, Wally ZL2MO, Paul ZL2HB, Blue ZL3TT, Errol ZL2IT, Mike ZL2VM, Peter ZL2HM, Stan ZL2ST, Michael ZL2MY, Peter ZL2IK and Karl ZL1TJ. Apologies: ZL2US.

Minutes of previous meeting: Read and confirmed to be correct: ZL2HB, ZL3TT.

Arising: The club’s 2m and 6m beacons are now fully operational after fitting the aerials by ZL2MQ, 2VM and 1TJ on 10.8 and heaving the mast back up with assistance of 2HB, 2MY, 3TT, 2IT and 2ALK on Saturday 12.8. Thanks to all.

Correspondence: Inwards: Bank Statements. Outwards: Article (re: beacons) to Break In magazine.

Finance: The club received a refund of $200 from lines company Unison.

General Business: Dave ZL2DW reported that, in spite of 12 people initially registering an interest in the proposed ‘Boot camp’ licensing course, only one has actually paid the prerequisite deposit. The course is now unlikely to proceed. A fairly lengthy discussion followed seeking the reasons for this and potential alternative approaches. Some of the comments made: Paul 2HB: Amateur radio needs to be promoted as a community service in times of disaster. Peter 2IK: Whangarei classes went well in March but a recent repeat saw no takers, perhaps too soon or else wrong time of the year for other reasons. Dave 2MQ: is Break-out sent to school science teachers? Dave 2DW: I have promoted AR to schools for years but nothing has ever come out of that. I suppose if youngsters want to find us they will through the internet. Paul 2HB: newspaper advertising? Peter 2IK:Rotary Club advertising does not work any more. Errol 2IT questioned the $200 cost. Dave 2DW explained the fee which includes membership for Bch 13 and NZART.

The fee may be partially waved in case of hardship. Errol: We need to re-brand ourselves as Radio Experimenters, doing away with the amateur label. It has negative connotations.

Blue reported contacting the Napier City Council regarding road signage. He was told that the NARC does not qualify for this service.

The meeting closed at 8pm.

Followed by Mike ZL2VM explaining his other interest namely radio astronomy. There is a branch of this science that, other than ‘listening to the Stars’ involves listening to electro magnetic phenomena in the Earth’s immediate envelope. Radio waves are generated by such phenomena as electro static build up and lightning but also through external influences such as solar flux and flares. Surprisingly, such electro magnetic waves exist at very low frequencies (VLF) and can be monitored with relatively simple equipment e.g. the sound card of a computer. Radio skills are needed to employ filters to block local interference signals. The topic is huge and Mike suggests the following resources for those interested:

Mike’s talk was followed up by Peter ZL2IK who shared his recent experimentation with WSPR, Weak Signal Propagation Reporting, which is in some ways related to the previous topic as it may also involve radio waves at audio frequencies. Peter mentioned Schumann resonances which are global electromagnetic resonances, generated and excited by lightning discharges in the cavity formed by the Earth’s surface and the ionosphere. This cavity forms a wave guide tuned to 7.8 Hertz. Peter’s WSPR activities are usually around 630m. Another fascinating talk.
