I use the DigiKey programmed chips with a Hayseed Hamfest board in a MultiElmac marine radio now on 75 meters.  The issue is the fact the rock 'comes on' when the stage becomes active, but you have to modify a rig to supply low volts to the chip, may be necessary to make changes to the oscillator circuit it feeds, turn the PLL chips on to transmit, off to receive or you get a carrier.  Unmodified radio life is a lot easier with a rock.
