I wonder if it covers the 30-meter band?

great improvement for AMTOR...but also becomes almost useless for 300

AM7910 modems have 200 Hz shift.

I started my RTTY career using 2125 and 2975 tones... until those young brats
started pushing the envelope (or should I say, squeezing the envelope) with

Regarding the AFC button, you may or may not want to have that turned on. It

That's an interesting frequency to select for the source of voice qrm. I
wouldn't be so fast to blame VE's or other non-US stations for this increased
interference. That is the BFO (14070 dial) frequency for virtually every
transceiver running PSK on 20 meters.
With the proliferation of PSK31

Hello researchers,
I am located in East Central Minnesota (45.4123 N 92.8823 W) and am receiving
the 6792.5 TX signal up to S-9 level. I have
I am not a sailor nor do I have any experience at sea. So as a layman, it is
unfathomable to me that anyone would risk their life venturing out of port and
rely on amateur radio for their communication needs.
Amateur radio for recreational use, certainly... a backup communication system,
On 7147 KHz at about 14:00 UTC today there was a 10~12 KHz wide digital signal
that was booming in. It's still there 2 hours later but only S-5 now. Can
anyone tell me what this noise is about? It sounds almost at bad as the old
Russian jamming signals from years gone by.

Andy,
There should be no detectable difference between an AFSK and FSK signal on the
receiving end. Are you sure your tones were correct on FSK? The symptom you
describe sounds like you may have been transmitting reversed tones. There is
a menu setting to flip the polarity of the FSK keying in
Andy,
In my opinion, that feature is in a gray area, between useful and practical.
I do believe this feature in the Icom has helped motivate many hams to give
RTTY a try. Once they see the messages being exchanged, it becomes an incentive
to investigate what is needed to participate. I suppose
Dave,
Those connections are correct if your FSK signal transmits right side up. If
you discover it transmits up side down, then use pin-4 on the PK-232 DIN plug
instead of pin-1. I think the Icom radios work properly on pin-1 and the
Kenwoods require pin-4.
