[TenTec] TT omni vii if port problems

[Greg S]

I highly recommend this mod, to allow full use of the SDR. Not sure why anyone would use the I.F. these days, honestly.

 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.

 it works fine on receive but the minute I transmit, am told
 I am off frequency.
