The full result sheets will be despatched to all contestants, various RTTY Societies and Amateur magazines both in Australia and overseas. The posting will be dalayed for about a week until all Certificates are prepared for inclusion where appropriate, oreoaration of the Plaques will probably take another month before final despatch.

Matters of interest: ------------------- Subsequent to information provided by N6GG it was found that typos had flawed the original issue of the Points Exchange Table. This has been revised (1994) and future contestants should ensure they use issues so marked. There were eighteen VKs recorded during the contest, but only six of these submitted logs. This is a pity because our standing overseas is enhanced when VKs are seen to be participating in what after all, is OUR contest. Rules, Log-Sheet, Summary Sheet and 1994 Exchange Table are now available for the 1995 Contest to be held 10-11th June 1995, a request to the Contest Manager at Box 93, TOONGABBIE NSW 2146 with an SASE will give you a copy of these items which you may photocopy as required. Comments from contestants: ------------------------- SV2BFN A lot of QRN and someone stole 10 meters, only two QSOs ... JR5JAQ Tnx fine contest, cond not so good but see you next year. VE7SAY Maybe next year the bands will be better, cu next year es tnx for the QSO GW4KHQ Pleased to work at least one VK. I hope to improve on antennas by next year. VK2GOM I did not operate for long as was in the throes of putting up a tower/beam. Next year will be a different story... SP6CYV CU in ANARTS 1995 ... W9FFQ Again this year condx were very poor here.

Please!!! To: info-hams@ucsd.edu I need some help here. I have an Icom W21AT whose external power jack no longer works. The HT works just fine by battery but does not power up when the external power is plugged in. I know that the adapter is ok. I know that the problem is with the HT. Anybody out there ever had problems with the external power jack failing? Anybody out there have suggestions on what I might look at? What happened? The ht sustained a 4 foot fall onto carpet (it was also in it's little soft case). The radio was fine, but the tone card inside was kinda jarred loose. So I took the radio apart (via instruction manual instructions. However, although I turned off the power, I didn't disconnect the power cord. While removing the metal battery lead, I apparently shorted the battery terminal. I found nothing to smell fried, and saw nothing unusually brown or black. Is this beyond simple search and repair? I'm having the schematics sent to me from home.

UPS lost them and made Tucker and me very mad. They had excellent customer service when I was working with them to remedy my situation. After UPS settled with Tucker, and the 2 HTs were shipped, one of them had a tuning problem on RX. I called Tucker and returned it to them. I had a new one within 5 days. Some of their prices can be beat, so it pays to shop around, but that is true with everything today. I also recommend Ham Radio Outlet, especially their Denver store.

Subject: VK2WI Weekly News, 25 September, 1994 To: info-hams@ucsd.edu This is Michael Corbin VK2PFQ Late last week I received the final legal account from the Divisional Solicitor. The matter was not mentioned on last weeks Broadcast, as I was unable to determine the exact information regarding the actual amount paid out to date. In the Annual Report it was stated on page 10 that the amount of money spent on all legal advice was $31,494.00. Try as I may, I could not reconcile this figure with the accounts paid to the Solicitor and the Barrister. This was made doubly difficult as the accountant is presently, not in the country. Accordingly, I obtained fresh information on these Accounts, independent of that shown in the Annual Report. I will not disclose the exact details on this medium, the next Annual Report is the place for that. What I will reveal, is that an additional account for $16,062.60 has been received from the Divisional Solicitor. This was for his work in the Tower Case, as well as for advice in the matter of the removal of certain persons from membership of the Wireless Institute. This gives a total of $47,556.60. The only problem is.... that with the information I obtained, the total amount payable now adds up to $54,012.97. There is a discrepancy of $6,456.37 which is yet to be explained. Hmmmmmmmmmmm!!!!! No matter the discrepancy, the fact remains that this organisation has, I believe, spent enough money on legal fees. The Lord only knows what it has all cost when you takes into consideration what it has cost the "other Side" (sic).....Surely that would put the amount up in excess of $60,000......and what did it all achieve?????? In my opinion, all this expenditure, EVERY LAST CENT OF IT COULD AND SHOULD HAVE BEEN AVOIDED....... Just think what we could have built with this money.........what a station we could have had here at Dural..or What a....etc etc etc etc. The Institute has sponsored our expensive legal system enough. I'm sure you will all agree. Regrettably, however, to finally reach a conclusion which will not see this Division in a state of confusion for ever, Corporations Law requires that we refer our circumstances to the Court for a decision. During the week I have had discussions with several of those who opposed ratification of the last election. This has caused me to place the matter before you once again. I realise it's a bit late but I believe we should leave our options open to avoid the cost of lengthy litigation, which means, MORE unnecessary legal expense, as well as the cost of a new Election. Our choices are: 1st option : We seek ratification of the last election. The legal advice here seems to indicate (in lay terms) that, if there were no objections, the Court would approve this ratification, approve it quickly and with minimal cost. If even ONE MEMBER (perhaps someone who did not vote in the straw poll) objected to this course of action. The Court would have no option other than to order a fresh election in a manner decided by the Court. 2nd option: We could approach the Court and ask to hold a fresh election; Requesting a ruling as to the precise manner in which this election should be called and conducted. In lay terms again, the Court must consider submissions from the Institute and individual members before setting out the exact manner and method for this new election. Any decision of the Court would, of course, be binding upon all members of the Division. The election would be held strictly in terms of the direction given by the Court. Both options will cost money. Option one is the cheapest and the cheapest by far. So members we have a dilemma. I need your input urgently. My personal choice is obvious ...It is Option One..... ratification of the last election and why? .... Because $54,012.97 is too much to spend on legal fees. I must advise you that to date we have not payed for any advice on the current matter concerning the last Election. I believe we all want this matter cleared up, as cheaply as possible. I'll say it again... Just imagine what we could have achieved for our hobby with that amount of money. The mind boggles! To this end a special Open Forum will be held next Friday night 30th September, at 7.00PM at Amateur Radio House, Parramatta to decide the issue. Members only of course. Time limit on the meeting 10.00PM. Let's put this issue to bed and get on with it, without further ado. I for one have had enough, haven't you? It's your last chance.....BE THERE!!!!! Country members are encouraged to send letters or faxes. Let's hear what YOU have to say. My fax number is (02) 626 6066. The Institute Fax Number is (02) 633 1525. If you wish to 'phone in your support do that as well. If you like, register your preference TODAY at the end of this Broadcast in the following manner. Yes OPTION 1 or Yes OPTION 2. IT'S YOUR INSTITUTE!!!

However there isn't any : suitable RF spectrum available for such an undertaking. : Curtis Wheeler San Ramon, CA (cgwh@chevron.com) It's not just the spectrum, there's the space needed for duplicate antennae, radios and controls. You certainly wouldn't want to do this on an aircraft, but even on the ground (the place where duplication would be essential) the nuisance factor just builds up. Duplicate VOLMET, duplicate VOR networks... As you said, technically possible, but administratively very challenging ! I'm assuming that aircraft would not need to go dual mode, that any spectrum would be too far away for antenna sharing, and that anyway, a clean separation would be needed to allow the old gear to be junked at the end of the overlap period, without forcing any refitting of the new stuff.
