[Elecraft] XV144 transverter - output power instability

[Johnny Siu]

Hello Group,

I notice output power instability in my XV144.  After I tuned the max outpu=
t power by R22, I closed the XV144 with the top cover.  However, upon tight=
ened the screws on the top cover, I notice a 20-30% reduction in output pow=
er.

I tightened all the screws and keyed the XV144 again with my K3.  I notice =
a output power facilitation between 12 - 18watts in my Kuranishi VHF/UHF po=
wer meter.

Could any of you advise what is the likely problem and how to trouble shoot=
ing?

TNX & 73
