[TenTec] TT omni vii if port problems

[Bob McGraw K4TAX]

Do you have any application associated with the device controlling the 
radio?  Also, if you are tuning to a signal using the dongle, it may be 
incorrect with regard to frequency thus this puts the Omni VII off 
frequency.     You may need to perform a Master Reset on the Omni VII.  
There are known some software applications which do shift the VFO, 
although not displayed as such on the radio.  This will produce and off 
frequency condition.

I had a a 3 Rivers Dongle on my Omni VII and it worked OK.   The 
software was a major pain in the posterior to get running correctly.    
Finally I wrote it off as a learning experience.   I then purchased an 
SDR Play  RSP-1 receiver and downloaded free HDSDR software.  All issues 
resolved and it works great.

I also made the mod to the Omni VII for the 2nd receiver which I find 
works even better.  With the SDR Play I can see signals on the entire 
band, thus not limited to the IF bandwidth.  That works great as well.
