Kathy, Yes, I have tried the Elecraft transverters with the Uniden 2600 - it has been a while, in fact during the transverter Field Test. I did not build this for myself, but I was building it for a client. A couple changes in the transverter keying were made as a result of testing with the Uniden.
There are two major problems with the Uniden 2600. First is the power output level is in excess of the maximum drive that the transverter can handle. That problem was solved with a 10 dB attenuator that was switched out of the circuit on receive (using a relay). The second problem is that the Uniden 2600 has no output corresponding to a keying circuit, so either the transverter must be activated at the same time the Uniden 2600 is keyed (direct from the keyline) which can cause the transverter to go quickly from transmit to receive and back again with the keying (and also the relay associated with the attenuator will work overtime). This problem is not as severe on SSB, but is still a consideration, and on SSB, the PTT must be paralled to activate the transverter. There is a solution to the second problem that does involve modifying the Uniden - I forget exactly where it is, but there is an 'I am in transmit state' type of signal inside the Uniden that could be brought out as a 'transceiver keying' output, but this signal is not available to the outside of the stock 2600. 73, Don W3FPR > -----Original Message----- > > Folks, > > I am interested in building the XV144 transverter.
