with WSPR. As I said in another posting, it is the power of deep space communications, based on heavy coding, coming down to earth. Peter Martinez did the first step when devising varicode, Pawel carried it further ahead with Olivia using Walsh codes, and now Joe carries it farther ahead to a

Re: [digitalradio] Re: 30m Usage....

Where was that? 48 to 54 MHz, or somewhere else? The only old reference I remember, from a 1936 Frank Jones Handbook is that 5 meters was 56 to 60 MHz (double of the ancient 10 meters band, before the 300 kHz snip on its top). I am not really sure of how things evolved from the old 5 meters

Re: [digitalradio] Best line of the day

I agree. Static crashes are a powerful QRN source here too. Guess Olivia would be better, even 8/250 would stand a better chance of good copy. In spite of strong signals, if there is no "second chance", it does not matter much how clever Varicode is. It is certainly a big step ahead

Re: [digitalradio] TCVR and frequency stability.

Gil, TCVR means (T)rans(C)ei(V)e(R). It explicitly says "transceiver" in the second line of the message body. 73, Jose, CO2JA == rojomn wrote: > What IS TCVR and where is it found? There is no reference left in your pos

Thank you, Darrel. I have not downloaded them, will try to get the images to burn here and give them a "test drive". 73, Jose, CO2JA --- Darrel Smith wrote: > Jose, > > I use the emcpup disk <http://www.w1hkj.com/emcpup.html> by Dave, W1HKJ > and ham_pup &l

Re: [digitalradio] Computer OS

I would advise you to try Puppy Linux and PSKmail Live CD's (baed on Mandriva) and see if any of them suits your expectations. The latest PSKmail CD I have includes Wine and some older windows ham apps that work well. I installed it to my hard drive on a P4 w/ 512 MB RAM. The latest Pu
