PSK31 Freq's


Steve R
 

One of the clubs members sent me the following from QSL.net saying that these are new PSK31 Frequencies. I have not heard of such changes and of course still making contacts at .070 where applicable. He is claiming these are active now. Ahh, I am making contacts on standard freqs.  Anyone heard of this change or seen this?

I agree with you....I am trying to trace down this source of misinformation.....where and why is this posted on QSl.net? 
HAs anyone heard or seen this chart and source?

I believe it is the original frequency list from before PSK software had waterfalls with see and click.  That is why the frequency is listed down to the hertz level.  You had to set your radio on the exact frequency blind to make a contact.

Ahhh. Ok. So this is an old list not anything new. 
Makes sense. Just trying to straighten out a local club member who likes to argue.

I told him to go ahead and set on those Freqs and let me know how many QSOs you make, hi!

With most radios and software setup using a 3kc waterfall bandwidth setting the radio at 14.070150 leaves a bandwidth of 2.850kc in our normal range so it is a very small difference on 20M.  40M is 10kc off the current range so nothing would be seen of PSK there.  Just a huge difference between current use of a radio setting and the waterfall using the 3kc bandwidth and then when you had no bandwidth.

Bill is exactly correct. The .15 is the giveaway, for precisely the reason that he states.

This is from way back in 1999, when PSK first came out (and PSK31 was the only variant). By 2000, new software had come out (DigiPan was one of the first) that did the tuning in the software instead of the hardware, so the "down to the Hz" went away. You can read about all of these "new" developments in Rick Palm's "PSK31 2000{ article in May 2000 QST if you search the QST archives.
