[hpsdr] diversity with Metis 1.1

[Joe Martin K5SO]

Hi Wully,

I have been out of town for the past week without internet access so  
have not had an opportunity to work with you on your problem.  Thanks  
to everyone who has helped.  Maybe I can help too with sorting out  
your diversity problem.

1)  You should be using Metis v1.1 in your Metis board.

2)  You should be using Mercury v6.4 for diversity operation, not  
v6.3, although this is not likely to be the cause of your reported  
Mercury 2 problem.  The difference between 6.4 and 6.3 has to do  
mostly with how the Mercury firmware version numbers and ADC overload  
signals are handled but the IQ data stream is handled the same for both.

3)  You should be using PowerSDR v1.19.3.3.diversity19 for diversity  
operation.

4)  You are correct that Mercury-EU uses different pins than does  
Mercury-TAPR.  The fact that your system runs diversity okay with Ozy  
indicates to me that you have handled the different pin out  
configuration of Mercury-EU firmware properly.

5)  What version numbers are being reported by PowerSDR  
v1.19.3.3.diversity19 in the Setup > HPSDR > Firmware version window  
for Metis/Ozy , and Mercury?

The version numbers should show as

Metis 1.1  (when using Metis)
Ozy 6.3    (when using Ozy)
Mercury 1:  6.4
Mercury 2:  6.4

by the way, the lastest Penelope code is v1.3 (not 1.2) but that's not  
causing your Mercury 2 problem, of course.

Please verify that the above version numbers are in fact being  
reported by PSDR.  Sometimes, I have noticed, HPSDRProgrammer will  
report successful updating of the Metis (or Mercury) firmware when  
actually it hasn't updated anything at all.

If Metis has not actually been updated to v1.1 things won't work for  
Mercury 2 (which is what you are reporting as happening) but it would  
work okay for Ozy operations;  please check the PSDR window to see  
what version is actually contained in your Metis and other boards,  
even if the display and reception for Mercury 2 is messed up.

I may not be able to get back with you on this problem until this  
evening but I will be looking for your reply.   Good luck!
