Re: [Elecraft] K3: 2 meter SSB/CW Capability Questions

[Phil Hystad]

Thanks for the comments I got and answers to my question (below).  I will 
probably go with the K144XV plus reference lock board but will wait until it is 
warmer weather to get my 2-meter antenna up.

Steve and others,

My best 2M MS contact was running the K144XV with the phase lock board 
and a BEKO amp at 800W into a 6el yagi in my attic. Over 1100 miles as I 
remember. It was a good combination.

One possible way to make a decision is to consider whether or not you might 
want to try meteor scatter on 2m using MSK144.  The recommended absolute 
frequency accuracy for that mode is 25 Hz (though I think you'd get away with 
80 Hz). This is a real challenge at 2m and the XV144 isn't really up to it, 
though I have managed a few MS QSOs using a K2/XV144/amp combo.

Phil,

I have had no problems working MSK144 on 2 meters as well as EME using the 
K144XV internal option with my K3S.

[Elecraft] K3: 2 meter SSB/CW Capability Questions

[Phil Hystad]

I would like to have a “weak” signal, SSB/CW, capability on 2 meters.  I have 
three ways of achieving that for my K3:

1.  The K3 (K3S) K144XV built-in 2-meter option module at $469.90 (price 
includes the K144RFLK reference lock board).

2.  The external XV144 transverter at $479.95.

3.  A third-party, non-Elecraft solution which I have not really considered.

First, clarification, I understand that the XV144 works with the K3 and I also 
understand that it is older technology compared to the K144XV but I have no 
idea if this matters.  The advantage I see of the XV144 transverter is that it 
provides higher output at 20 to 25 watts.

What are the pro/con of these two different (items 1 and 2) ways of getting 
2-meter capability.  Note: I have no interest in FM.

Thanks,
73, phil, K7PEH
