[TenTec] Re: [Orion] Raspy Receive CW Note Problem Solved

[Joe Giacobello]

Rich, thanks for your confirmation that this is a known problem and that 
a master reset eliminates it.  BTW, the problem resurfaced last night 
about 60 minutes after I had tried the reset.  I have not connected the 
behavior with any particular mode or function being on.  I have only 
used the Orion on CW so far.  I do use the sweep.  I noticed that the 
received signals did indeed seem poor and the band (40M) sounded very 
noisy last night.  I wasn't sure whether it was the RX or the band was 
lousy.  (Unfortunately, about three days after I received the Orion, my 
1000MP lost its audio and I had no way of comparing the two.)  I didn't 
notice any lettering as you describe and I never lost TX function, but 
I'll be checking things again this morning.

Up to this point, the unit had been working well and I had been fine 
tuning parameters according to the manual and Sinisa's and Yuri's 
suggestions.  I actually thought the September revision to the manual 
was pretty good.  I notice that Sinisa's and the manual's "all purpose" 
AGC recommendations differ, but I'll be comparing them more thoroughly 
as I get to understand the AGC parameters better and become more 
familiar with the rig.

Thanks for your help.


73, Joe
