- Look at the Windows program created by W5XD -- a demo version is
- available on the CompuServe Ham Forum, and some other outlets.
- You can also contact Wayne directly (he is good in the book, Round

-
- Steven has hit it on the head. As hams, we have for years said "can't
- afford a commercial rig? Home-brew or build a simple kit." Then
- QST and all the other magazines which bang this drum (which quite
- handily fills up magazine pages with circuits that few ever
- build) reap big advertising dollars from kit companies.
-
- We, as a hobby, actively encourage newcomers to try these things
- out.
-
- As a hobby which has a tradition of mentoring ("elmering"), we are
- doing the Right Thing(TM) when we identify something like a Ramsey
- kit which is apt to blow a new ham's radio budget out the window
- while discouraging him or her, and leaving him without a working
- rig. I'd much rather see a Novice/Tech find an old but serviceable
- IC-2 (and maybe put the Ramsey 'brick' on it) than have him or
- her get their hopes up on the FX- kits, only to be disappointed.
-
- I fell into this as a newcomer. I bought a Heath HR10-B and found
- out that construction was a LOT harder than thinking about it. And
- for the price, I *could* have found a used, solid, working receiver
- and saved much grief. I still would have done some construction,
- (QRP transmitter, Xtal calibrator, etc.) but would have initially
- tackled less imposing projects.
-
- Keep in mind, this was with a Heathkit, which was absolutely the
- best. I think all of us who knew Heath know that Ramsey is no
- Heath.

-
- Russian Amateur Radio Emergency Services (RARES) was born
- during the turbulent days of the Chernobyl tragedy. But RARES
- true abilities emerged in December of 1988, at the time of
- Armenia's devastating earthquake. No communications were
- available with the disaster zone, with a notable exception of
- amateur radio. Our emergency network was fully operational two
- hours after. Rescue teams, as well as the Disaster Relief HQ
- in Moscow and Armenia, had their communications provided by
- RARES and the amateurs of the former Soviet Union. May 1991 -
- another earthquake in Georgia - and again RARES assisted the
- search and rescue teams. There are many similar examples, where
- RARES provided invaluable life-saving links, in situations
- totally lacking goverment communication support.
- On August 19, 1991, the faithful day, when democratic
- movement in Russia was hanging by a thread, RARES station
- begun transmitting Boris Yeltsin's decrees to the peoples of
- Russia. And the following day, R3A became operational from
- Moscow's "White House", providing communications support for
- three days to the President of Russia, the members of the
- Parliament and the "Radio Russia", when the putschists took
- control of media and telephone facilities.
- We, the RARES members, are ready, willing and able. We are
- ready to react immediately, in Russia or anywhere else (like
- during Iranian earthquake of 1989), where our help is needed.
- We are a thousand-strong with members all over Russia. Our
- sole purpose is to provide disaster relief communications. We
- do the job, but at present lack outside financial support and
- modern equipment. High on the list of our needs are mobile and
- portable equipment, generators, means of transportation and
- tents. We are in dire need of digital communications
- equipment. Any and all assistance would be welcome and
- attention to our needs would be greatly appreciated.

- Subject: Seeking Opinions of Memory Keyers
- To: info-hams@ucsd.edu
-
- I have a Logikey, an AEA MM3, and a MFJ (newer model with the "menu
- system"). I vote for the Logikey. Smoothest keying, most integrated
- operation. Most ability to embedd instructions in the memories (ie:
- programming the memory, in addition to saving code, that is). My only
- complaint is that it only has 4 memories. I would really want at least 8.
- However, I still think its the nicest overall.
-
- Will run off of a 9v battery (although I havn't tested how long.
-
- Mine had a problem - it generated RFI in the 17 meter band - in the CW
- subband (imagine that - a keyer generating CW RFI!!). I called W9KNI, and
- he suggested more shielding. Added several wires, slightly bent the audio
- cable I was using to key the radio (to improve shield contact), and the
- problem went away. My guess is that they all cause slight RFI, but most
- outside of the CW subband, or outside of the ham bands entirely. If this
- was the case, I never would have known of the problem, and it never would
- have bothered my.
-
- Hope this helps

- Hi Conway, I have both 250Hz and 500Hz CW filters and I prefer the 500Hz.
- The center frequency 750Hz component in the background noise bothers me with
- the 250Hz and it does ring worse than the 500Hz filter.
- The big boys tell me that 250Hz filters are for "really serious CW".
- I'm hardly ever serious.
