In all this time with K3 #24, I've never been stymied by any issue
such as described below.
I'm a Navy-Marine Corps MARS member. We use RMS Express in the WL2K
system on HF, running WL2K Winmor mode The software I have is version
1.1.3.0.
I also use LP Bridge to create two COM ports: one used for DTR (PTT)
and the other for control, COM19 and COM20 respectively. The sound
card is an EMU 0202.
The problem is this: When RMS Express takes control of the K3,
calling an RMS node on HF *always* results in the receive frequency
being 1.5 KHz too high. I've had to rotate the RIT between call-up
transmissions to get the RX on frequency before the initial 5 attempts
time out. The TX frequency seems dead-on, because the RMS always
answers - but RX is 1.5 KHz high. And yes, I've tested with multiple
RMS nodes, including my own NMCM RMS here at the shack. Same problem
occurs with each, so it's a setup issue with software or the K3 here.
RMS Express sends the following commands after it's set the COM20 comm
parameters:
FR0; # cancel split
RT0; # RIT OFF
XT0; # XIT OFF
MD6; # TX DATA mode
DT0; # DATA A sub-mode of TX DATA
The sequence above is sent once at the beginning of an RMS Express
call-up of the remote node. Only COM19's DTR is used to assert PTT
for transmissions.
Just for grins, I checked the various meta-modes the K3 is in. I
discovered that even though AI is set to ZERO, I'm still getting IF
annunciations back from the K3. Odd, that.
K31; # K3 extended commands enabled
K22; # K2 extended " "
AI0; # AUTOINF OFF
Since split and the incremental controls are off and ZEROed, I'm
totally blind to what's going on. VFO A is on the correct frequency
in each case (for each RMS Node), which means to me that RX and TX
actual frequencies should be the same.
Any ideas what's causing this?
