Amateur Radio Calendars

At Conference Peter Loveridge ZL1UKG was advertising an amateur radio Calendar, details of which are below if you would like to order one.

The calendar covers July 2010 to June 2011 so it ties in with Conferences.

The date information includes public holidays for NZ and Provinces plus contests on both HF and VHF that are managed from New Zealand. The photographs are chosen from activities associated with the hobby and in this year include history (Musick Memorial radio station), AREC (Rally of NZ), Telegraph and SPAM equipment, VHF Contest, a "shack" and equipment, Kiwi Sat, a Working Bee at the Klondyke repeater site.

The cost is $13 per copy. Postage is $1.50 for up to 4 copies in a C4 envelope. Inquiries may be addressed to the Auckland VHF Group or to Peter Loveridge, 5 Mostyn Street, Kingsland, Auckland 1021, email peterlov@ihug.co.nz

Payment may be by cheque or Internet Transfer to 12-3019-0781605-00. Payment is required before the order is posted out.

Please do not send any order requests to NZART headquarters.

Nelson Branch

Members from Nelson Branch have arranged to keep a daily sked for a special expedition of six young sea cadets sailing to Noumea starting from Saturday 3rd July. For more details see the following web site:

http://www.stuff.co.nz/nelson-mail/news/3865181/Cadets-sail-to-Noumea/

You are invited to monitor this activity at the sked times (and also 147.025 for talkback to Nelson Branch Members operating)

Full details of frequency and times can be found at:

SMART Applications for a Certificate of Competency

I may have mentioned, but it is timely to do so again. As at 1 October 2010,it will be mandatory for any new Certificate of Competency and call sign application to include a passport photo. A witness must authenticate this photo before being submitted with the Radio 4A Application.

Talk soon...Debby ZL2TDM

Answers to "A 1928 Description of Amateur Station 1AS"

Hi Jamie:

Yes, the "felix" was a play on words for "helix" which was the coil in the transmitter.

While nowadays we think of "helix" as the generic form of an inductance for hf work, in those days a flat spiral or "pancake" coil was also widely used.

Oil in the rectifiers. Presume this station used "slop jar" rectifiers to convert ac from the power transformer secondary to something like dc. The slop jars were electrolytic, made use of the principle that certain electrolytes with electrodes of different metals suspended in them conducted better in one direction than another. These devices were connected in series to handle the voltages involved. Oil was floated on top of the electrolyte to stop it from evaporating under natural conditions or the considerable warmth generated by the passage of the current through them when in use.

Most electrolytes were highly corrosive, hence not popular with her indoors as they sputtered at times and burned holes in carpets, wallpaper or pet animals.

"Troubled Hartley". The typical Hartley power oscillator had a parallel tuned circuit between plate and grid of a valve, with a tapping point at rf ground somewhere along the coil, typically about 1/3 way up from the grid connection.

There were numerous techniques used to couple the power from the oscillator to the antenna. Could include tapping the antenna directly on to the coil, or various capacitive or inductive methods. So the final result could well be a "troubled" Hartley.

Although these transmitters were very simple, in fact there were many variables and it usually required a great deal of nous and experiment to get one to work well.

Notwithstanding, the globe was circled with just such technology.

Barry ZL1DD

Ps ZL2JJ has a replica 1929 TPTG single valve tx which he has used with success on 80m, even showing up well in the Sangster Shield. First time I ever worked Peter he was using this rig. Lovely bell like note, frequency shifting slightly and ever so slowly as his antenna swung in the breeze. Interested persons might drop him a line, could get a demonstration.

Thank you Barry
The whole machine sounded mighty primitive to me and your description confirms it.

ZL1CLUB HF Node

Do you not have the space for a 160 m dipole?


Do you have difficulty hearing on some HF bands due to high QRM?


Do you do not have a tri band beam antenna but would like to use one?


Have you moved to a new QTH and are not able to put up HF equipment?


Do you travel a lot and want to be able to access HF to make contact with your Ham friends?


If you can answer yes to any of the above questions then we may have the answer to help.


Why not try the ZL1CLUB HF node at the Papakura Radio Club, go to:
http://www.qsl.net/zl1club/
and learn all about how you can have access to the ZL1CLUB Link, a shared HF station to help you keep in contact with your ham friends.

Internet Connected Amateur Radio

The Ministry has raised some concerns with NZART about IRLP, D-Star, Echolink, APRS and similar modes as they do not appear to fit within our current licence (GURL) conditions.

Concerns raised include:

*the use of unattended transmitters and unlicensed digipeaters for APRS and

*Amateurs based overseas operating (via the Internet) a NZ amateur station.

The ALO, Don Wallace ZL2TLL is currently putting together a paper on this topic and would appreciate input from interested amateurs.

Will anyone interested in contributing please send an email to

alo@nzart.org.nz with "Internet Connected Amateur Radio" in the subject line

Please feel free to contact me with any queries.
