[Elecraft] XV144 calibration

[Michael Jensen]

Proberly i should try this one on the hole list as well, sorry don for you 
getting it twice.

Hi Don

again thanks

The SSB Firmware was ok, version 1.8 so no problem there.

Now i have found the issue on the K2, but not the solution. The desribed 
issue seen on the low power out are comming from the 28-30 Mhz. if i check 
indicated power by the internal powermeter it drops over the freq. with the 
power set for 5W i do reach 5.4 W on 28 Mhz at 29 Mhz it is 4,9, still ok 
but at 30 Mhz it is down at 0,3 W
So trying 10 W 29 Mhz only goes to same 4.9, so a rolloff on increasing 
freq. are seen. Proberly normal, but passband seems to be to narrow ???


Any idea is this normal ??
Thanks in advance

  Michael,

  If your K2 is SN 5111 and the KSB2 was ordered at the same time as your 
K2, then you have the latest KSB2 firmware - Elecraft does not ship any 
options with back level firmware.

  Yes, if you could achieve only 0.17 mW from the K60XV in TUNE with a 1mV 
MENU setting, that is the problem that must be resolved first.
  I believe you have something wrong with the K60XV, and I am stumped at the 
moment.  I do not have the setup to try what you suggested here at this 
time, but the behavior you describe is not normal.

  Perhaps Gary Surrency can provide some further information and guidance. 
I am copying Gary on this email.

    Thanks Don

    Good point, i have proberly been a little careless on this SW 
requirement, as i got the K2#5111 with all options in one shipment from 
Elecraft. I guess they normal take good care that the right versions are 
included when shiping together. But i will indeed check as soon i get home 
from work.

    If you are the owner of the XV144 and using it in the Low power setup, 
could i ask you to use the tune button to TX the transverter with the power 
set to the full. and the see if your K2 display will show  the 1 mW about. 
In my case it showed something like 0.17mW with the power set to full 1mW, 
and i tuned the XV144 according to that. Only now i think about if that 
display was really true i have tuned the XV to deliver max power at 1/5 
input. Then maybe if Keying with the mike. are giving the 1mW no wonder i 
overload the XV.

    Thanks in advance

      Michael,

      Check the 'Firmware Requirements' section of the K60XV manual.
      You must have Version 1.07 or later of the KSB2 firmware installed to
      provide proper power level control when using SSB through the 
low-power
      output.

      It does sound like you have an earlier version of the KSB2 firmware.
