Adriana & Lexa - I have both the external XV144 and the internal K144XV. While they both have their advantages and disadvantages it all depends on what you want to use them for.
For frequency stability the XV144 (with crystal oven) is far superior although Elecraft are currently doing some work towards reducing the drift in the K144XV. The internal transverter is fine for FM but I am finding the frequency drift of mine is unacceptable for CW or SSB unless your overs are very short. I understand that Elecraft are planning to provide a facility to lock the oscillator of the K144XV to that of the K3 which will cure the drift problem. To sum up, as things are at present, it's the XV144 for performance but the K144XV for convenience. 73 de David G4DMP In a recent message, Alexandr Kobranov <[email protected]> writes > >As I am now to decide to buy K144XV or stay with some external - let >me ask here: > >What is thermal stability of internal 116/118MHz Xtal osc? >I mean some experience with JT data mode in EME or similar.
