Note 1:   Some radios require a higher audio level for VARA FM Wide or 9600 baud connection speeds.
The DRA-30, DRA-34 and DRA-36 have lower transmit audio level capability that may be insufficient for some radios, especially at higher speeds.
Note 2:   Many programs like VARA FM, VARA FM Wide, VARA HF, FLDIGI, Direwolf, and SoundModem don't require VOX, but FT4/8, SSTV and some others do.
Note 3:   Some ICOM radios don't respond to transistor keying circuitry. A relay alleviates this problem.
The ICOM IC-706MKIIG and ID-880H are two such radios requiring a relay.
