[MRCA] AN/GRC-106 on LSB?

[Mike]

Thank you Steven. Your information is well received!I don't have the -106 set just yet, but I am exploring it's capabilities before I do ever pull the trigger Can you tell me... is there anything you dislike about the 106, or something you wish it could do but doesn't?Basically I'm looking for any reasons why someone wouldn't want one (besides the obvious like bulk or weight)Thanks...MikeKD7VRG

    I've been looking to do this with my GRC-106A too. There used to
      be someone who made the xtal filter in asia, but sadly no more.
      From what I gather you use a DPDT shielded relay with a 24v coil
      to switch the original USB xtal filter with a LSB filter. The coil
      is connected to the front panel switch to change when the FSK
      position is selected ( that's what I was told). I did find a LSB
      xtal filter for another radio that supposedly works with the IF
      frequency of the RT-834. The parts are sitting in my shelter with
      the radio, yet to be installed. The parts could fit in the module
      or nearby. Sorry to not offer more specific information. I'm still
      in the theoretical stage until I pull out the soldering iron. I'll
      look at the filter and give you more info and pics. Home with the
      Wuhan flu, so have lots of time to wait on SCØUT and stuff like
      this.

      Hello,
        
        I have a question about the GRC-106 (RT-834)
        
        I'm led to believe this radio can be modified to work on LSB. 
        Is it just the LSB crystal filter that 
        is needed?  Does this ADD LSB and still retain the USB
        capability, or does it REPLACE the USB
        with LSB?
      
        Is there anything else that needs to be done besides installing
        the filter? How difficult is it to do?
        
        Thanks...
        
        Mike
