Hi Adriano,
I use the K144XV Internal unit and I reckon its a better buy than the external
unit for a couple of reasons.
1: Convienience - No external cables to lose!
2: Coverage of the full 2m band versus only 2MHz coverage of the external unit.
The only down side is the lower output of the
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. Is there
some drift on 144MHz signal (during longer TX period) and how much if any?
Thanks
Hi Alexandr,
I have not noticed any drift at all with my K144XV with internal temperatures
to +60 degrees C.
I must admit though at this stage I have not used it for digital modes, only
SSB + FM.
No-one has ever commented about any drift on my signal.

A 20 Hz mis-tuning of a SSB signal usually will not be noticed, 50 Hz
maybe, and 100 Hz definitely.
So yes, you would normally tune the station until it 'sounds right' and
then transmit. That assumes that you are using the same filter for
transmit and receive.

I had to change the name of APF SHFT to APF SHF (discovered the
