Hi Wayne,
Because of this, we've decided go with 10 m (28-30 MHz). The K144XV
to avoid potential interference with a 10m station work ing from the
same location, wouldn't it make sense to use something like 30 to 34MHz
as the IF?

will still cover the full 144-148 MHz range by using two local
oscillator frequencies (116 and 118 MHz). If you tune across the
boundary at 146 MHz, the oscillator will switch automatically.

I believe that the reuse of ten meters can be transparent IF desired, and
the hi-lo range switching will not happen while going RX to TX for any
common use I know about.
K3 will show the 2 meter frequency when using the radio as an IF. The only
change is what band in the K3 is used as an IF.
That may be true, and it will probably be transparent as you
indicate. Other small interest groups (with apparently not as much
pull) can't seem to get other promised and advertised features
delivered that have no side effects at all, although I think all of us
paid the same price for

For instance 146.3 recieve and 145.7 transmit... does the oscillator
also switch?
Yes. But I don't know of any cases where normal repeater splits go
across 146 MHz. And in

I dont see a problem with this change.
Is the August delivery date still valid?
How about the daughter board to use it as transverter IF?

We're still shooting for the end of August, although the design change
and subsequent retesting may push this out a bit.

By using the 10m band those high power 10m users will have an issue - so I
don't see how it solves anything besides moving the problem between users.
6m and 10m tend to also go together with 2m.
Perhaps it would be better to use a different band entirely - say 32-36MHz
or 25-27 MHz and bypass
Wayne,
I saw the K144XV at HamCom in Plano last month and it looked like the 2m
antenna jack was mounted to the rear plate that is in place when the 100W PA
is not installed. Where does the K144XV antenna jack go for those who have
the KPA3?

On the same panel. The circuit breaker reset is a bit higher and the 2M BNC is

I suppose the rest of us (non-high-power high band multi-station
contesters) shouldn't care.
But it seems this is one of those things that benefits a very few
users at the expense of adding a bit of operational clunkiness for the
bulk of K3 users and to what was originally a pretty clean
