Hello Charlie and Bill.

So, this behaviour in no way impacts FO/W7GJ’s ability to decode my final 
rogers? These are very marginal signal levels as you know. I expected that his 
decoder would be looking for FO/W7GJ PA5Y RRR, it seems that the current 
situation is OK. I don’t understand the decoder fully yet.

Hi Conrad

I'm not sure there is any need to change the program with urgency.  If you take 
the messages that are generatied automatically and don't manually change them, 
then the RRR and 73 messages are transmitted with base calls and the program 
recognises this and decodes the RRR and 73 with full AP ie max decoding 
sensitivity.

Thanks Bill, you can imagine for marginal QSOs such as this when Lance is 
expecting RRR it could be an issue, he is there right now. Any chance that this 
can be fixed as a matter of some urgency please

Hello team.

Last night I was attempting to work FO/W7GJ on Q65-60A. My question is about 
the population of TX4 and TX5.

When I Generate standard messages, I see TX1-3 are correct.

TX1        <FO/W7GJ> PA5Y JO21
TX2         <FO/W7GJ> PA5Y -27
TX3         <FO/W7GJ> PA5Y R-27

However, the compound call is omitted from TX4 and TX5

TX4         W7GJ PA5Y RRR
TX5         W7GJ PA5Y 73

Is this expected behaviour? I can see that it does not affect the validity of a 
QSO as all the necessary information has already been passed. However, I 
noticed last night the following.

0307  -8  0.0  699 :  FO/W7GJ <...> RRR

Obviously tropo but in this TX4 example the compound call appears to have been 
transmitted, whereas in my case above it is not.

Hi Conrad,

that appears to be a defect. Tx4 and Tx5 should be generated using hash codes 
rather than base callsigns. As you point out it is not too serious in this case 
as the full calls without hashing are exchanged earlier in the QSO. That is not 
the case with non-standard calls that are not compound so the issue needs 
repairing.
