Re: [Elecraft] VX commands don't work

[Wes]

I was writing about a K3S, but just for you I powered up the K3 that I keep as a 
backup and it works too. Are you appending the semi-colon?

 BTW, my K3S F/W is 5.62 and the K3 is 5.0.

Re: [Elecraft] VX commands don't work

[Kidder, George]

Well, now, I am both confused and eating crow!  Now it is working as 
expected.  I have no idea what I was doing wrong before.  Both the VOX 
function and the indicator are now going on with VX1;.

Talk of a tempest in a teapot!

73 and thanks - George

 The VX command is "GET" only, so you can determine the VOX status,
 but you cannot SET it.
 See the K3 Programmer's Reference Manual.

Re: [Elecraft] {KX3] KX3/PX3 Opposite Sideband Nulling -- Question

[Grant Youngman]

I went ahead, bit the bullet,  and recalibrated opposite receive sideband 
suppression on the KX3.  It was substantially off with both FL3 and FL2.  With 
FL2 I was able to get a very good null.  With FL3 the null was quite shallow, 
but better than before.  Not sure if the FL3 situation indicates an issue with 
the roofing filter module, or if that’s just the way it is.

I’ll run the radio and watch everything for a while before redoing the PX3, 
since that’s band-by-band and more work than I have time for today.  At least 
my 8640B still works :-)

Re: [Elecraft] new revision of KPA500 LPF T_R Switching rework Rev.E guide available

[w4sc]

I have serial # 1866.  I am the second owner, and Elecraft paperwork I received 
with the unit shows the unit was returned to Elecraft for “PA DISS Fault on 20M 
and 6M, with D10 and L6 being replace.

In addition , under warrantee, the T/R switch was updated ( Rev E?? ), and the 
12M mod was performed.  There are NO details as to  exactly what was replaced.  
There is no indication as to what the NEW rev level of the LPF would be as a 
result.

The upshot of all this is, if you have an earlier s/n, the above may apply!

[Elecraft] New Revision of KPA500 LPF TR Switching Rework Rev. E

[Roy Morris, Jr. via Elecraft]

I have an early KPA500, and it works flawlessly.  Is this mod recommended by 
Elecraft on ALL amplifiers that presently have Rev. D ?  This mod requires 
considerable disassembly, and I don't want to do it unless it is highly 
recommended.  Please state the specific reason for this mod.  Thanks.  Roy

[Elecraft] {KX3] KX3/PX3 Opposite Sideband Nulling -- Question

[Grant Youngman]

I’ve noticed (usually on 20M) that with the KX3 preamp OFF and a strong USB SSB 
signal tuned, that there is a LSB “shadow” on the left side of the cursor that 
shows up on the PX3 display, some dB down from the tuned signal.  This does not 
appear if the KX3 preamp is turned ON.  

Would this be normal with the preamp turned off?  Would it be reasonable to 
assume that either or both of the KX3/PX3 need opposite sideband nulling 
adjustments revisited?  And if so, should the KX3 be done before looking at the 
PX3?

At this point it’s just a niggle. The KX3 and roofing filter were shipped 
together from Elecraft and calibration was done at the factory.  Perhaps it’s 
drifted somewhat with time and just needs to be tweaked.

Thanks .,,.

[Petr, OK1RP/M0SIS]

Buck,

unfortunately I have not info about the s/n relate to revisions of the
PA/LPF boards.
The best way would be to ask Elecraft service for that.
I know that rev. D or earlier revisions could be modified if needed.
