[WT-support] WT, MK2R and the SWAP command

[Olivier F5MZN]

Jim,

Here is my observations/comments:

MM0BQI wrotte on Aug 8, 2007:
> SWAP function.  Intermittent and unpredictable results with frequency 
> display.  Most often happens after using the 'SWAP' command for the first 
> time. Thereafter VFOs A and B swap okay 19 times out of 20.
> example same mode
> Radio1(MP) VFOA 28500  Radio2(IC) VFOA 3780
> SWAP
> Radio1 3500 radio2 28500
> SWAP
> radio1 28500 radio2 3500

I am unable to repeat this using version 3.15.0. I did not try with 
older versions.

As I told in my previous reply, some commands are sent to the Icom for 
programming its VFO B. I have considered this again because it is indeed 
not possible to know for certain what is the frequency of the VFO B of 
an Icom rig. In other words: if you have two Radios, say one Icom and 
one FT1000MP: you can program the VFO-B of the Icom from the FT1000MP 
one but not the opposite. This can make a lot of confusions. That's why 
I have decided to give over VFO-B programming as soon as at least one of 
the radio is an Icom.

I confirm that mode changes were totally messed. Fixed in my devel trunk 
(please try the next nightly snapshot, which will be available from 
0400z tonight).

No way to repeat, expect when lauching two WT instances at once. 
Lauching two instances of WT at once is possible, but you need to have 
both installed in separate directories in order to get them having their 
own WT.INI. Of course, the same port cannot be opened twice.

Despite many many hours of testing, I never had a "chance" to get any 
communication failed. My Icom radio is connected through an MK2R. CI-V 
Transceive Mode is activated in both Win-Test and the Radio.

I have tried with the "Disable router queries" (microKeyer 2R settings) 
option either checked and unchecked. No problem.

I have also tried with CI-V Transceive mode disabled. My radio is 
scanning up the entire HF band for hours and it is still working perfectly.
