RTTY with K3/0

N7IP
I'm new to RTTY and could use some help. I must use the K3 FSK D capability because I am remote with the K3/0. With MTTY software, I can copy guys fine in NORMAL (not REV) mode. But the other guy sees me as either on the wrong sideband (I'm set for LSB) or reversed. If I hit the REV button on MTTY to fix that, I can't copy him. Yes, I know, it's a dumb question, but what am I doing wrong?

Bob,

In FSK mode MMTTY's REV button doesn't change the transmit polarity.
Transmit polarity in FSK is controlled by the radio, and the only thing
MMTTY's REV button can do in FSK is reverse the receive polarity, which
as you noted is the opposite to what you want.

To change the transmit polarity in FSK, use the K3's CONFIG:FSK POL
setting. I don't know for sure about your remote configuration, but when
using MMTTY locally CONFIG:FSK POL should be set to 1.

Thanks Rich. I tried changing the POL parameter to zero earlier tonite and it seems to work (1 is the default). Afterward, I worked XR0ZR without any problem or complaints (altho the DXpedition is probably not going to comment much!). I'm going to try to work some more guys this weekend to see if the POL=0 solves the problem with MTTY.

I've been using my k3/0 for a few days and can't copy rtty on it. the remote can copy, but only if disconnected from the rrc1258. Is this a configuration issue also?
