[Elecraft] XV144 paired with Uniden HR-2600?

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.
