Re: PSK31 Freq's

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.

One of the clubs members sent me the following from 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?
