[hpsdr] What is the Status of Munin?

[Kjell Karlsen]

Hi All.

At the moment I am at Gran Canary on holydays and I´ll be back home 1.  
December. I have Hermes/Apollo with me and try to be active every evening  
on 17 (18,140 +-) and 20 (14,158 +-)meter but the conds have notproblems  
been good during the dark time, much better early in the morning but then  
we are out walking or swimming!

I have installed Munin into Pandora and that works fine. As always with a  
transceiver, an input filter in the 13,8V line is very important to  
prevent what Pete describes. I have had no problems at all and I have  
tested with 24V and > 160W PEP output and 16 dB compression. If needed I  
can describe how I have installed everything into Pandora and post some  
pictures of the solution.

As Aivars say, everything now depends on TAPR. I think Munin with the last  
PCB layout is very good.

At the moment I am sitting on the veranda, temperature is 20 deg.C and it  
is 1900Z (and local time).

73, Kjell
