QEX is available as a membership print option!
FYI I had asked a few days ago about getting QEX as the membership print option. Much to my delight I received the following today from Becky Schoenfeld: " Our Membership Department has advised me that they can make QEX the magazine you receive as your primary ARRL membership benefit. They will put this into effect. If you have any questions about the matter, please contact circulation@..." Have Fun! Reg

High Q UHF coils and lines 2
Hi! I understand VHF / UHF coils are silver plated, not because silver has a slightly lower resistivity than copper, but more because silver oxide is conductive, whereas copper oxide not. This statement sounds a little strange to me, because silver oxide has a quite higher resistivity than the pure metal anyway. But let's leave it there. My question is: wouldn't it be far superior to use enamel copper wire, possibly adding a perfectly airtight lacquer on top of the enamel? That way Q would be preserved along the years better than with silver plating. Obviously I must be wrong, because otherwise nobody would take pains to apply the silver. Can anybody clarify this? Kind regards Daniel Perez LW1ECP

Welcome
I never imagined when I created the group that I'd get so many responses. It shows that the traditional ARRL DIY attitude still lives. I'm particularly pleased by the variety of people. I just wish I could figure out how to stop "new subscriber" messages. Thanks and have fun! Reg

Please reply to the original Introduction thread rather than start a new one
The idea is to make it easy to learn a bit more about someone before you reply to them. There is a very wide range of education and experience in the list. It is my hope this will help improve the quality of discourse so experts get the expert version and novices get the novice version. Reg

Introduction
Hi to all, Bob de K2KI in VT here. I have been a ham since 1984 and I originally held the call KA2UZC. While I have always been into Boatanchors and hybrid radios (Mainly Kenwood), I have always wanted to try my hand at QRP levels. I started off with an FT-817 which I had made made many contacts with that radio I had to sell after an accident which left me disabled. I do miss the radio! I started my pilgrimage to the land of QRP with Tony Park's Softrocks. I collected 160, 80 & a 40/30M units which I packaged all in one box and control with an Arduino. While I made some progress with this setup and a few contacts, more work with the Arduino was needed. I never finished it but hope to do so soon! I then collected starting Rockmite's starting with a 40M Original Dave Benson release. I put it in a "Mity Box" and have a Pico Keyer and Nescaf filter which is not installed. I did make a few local contacts but nothing past 300 Miles. I then received a 30M RM (Also original) which someone else built. It works well and has nice output although I have yet to make a contact yet. I have another Rockmite 40 in an altoids tine (also someone else assembled). I cannot get any output so that goes on the checklist of fun and exciting things for Bob to-do. I plan to have one for each band (with the QRP Gods blessing of course!) :-) I created a daily hour-long dance to attract their attention. But, only attracted the neighbors attention! (What? They never heard of Nekkid hour dancing to the QRP Gods???) :-) Maybe I should do it inside from now on! :-P I also picked up a very nice Midway ME-80+ that works wonderful. I have made a few contacts with one as far away as Ohio. Another two kits are Chinese kits. One is a "51 RM" for 40 with enclosure. The toroid's and the lumpy-Bumpy type red ones. KC9RON s has replacements plus rocks to bring it up from 7.023, I have to order these. And finally, a built Chinese 49'er that is in a plastic Tupperware style container. No contacts made on this yet. I recently received a DC40B kit which I am salivating over and can't wait to create some Solder Fumes. and have a great enclosure to put it in. I have two NC-40 bare board that will one day be working radios. Chuck K0QO seems to have taken down the videos he had for their build. My antennae's are: an 88' Doublet, G5RV and a TH6-DXX which is presently down because all the plastic parts I replaced back in 2015 disintegrated. I ordered new ones from Hy-Gain/MFJ but they are on backorder. For how long, nobody knows including MFJ. I have some Un-Un's coming and want to try an EFHW and a Long Wire. So, that us my present QRP me. Will keep my QRP bio updated when I can. -- Bob de k2ki k2ki@... k2ki.bb@... (Goes to my cell) 4SQRP #2292 FP #4214 SKCC #12195 NAQCC #2337
