I've just noticed that our club's K2/100 (#3764) draws excessive current on
topband.
Going through the bands my own K2/100 (#4368) draws between approx. 15-19A
at full power setting, (circa 100W o/p). The club rig draws between approx.
16-20A in the same test, but on topband the current consumption is 27A !!
I did not build the clubs rig, but the ham who built it has built several
K2's.
Both rigs have the latest mods/screening/upgrades, including the PA
instability fix for 80m. There does not appear to be any instability on
topband - I've checked on a scope and spectrum analyser.
It's possible the club's PA missed out on a mod early in it's life?
Any ideas please? Looks like it's short of some L or C somewhere.
Thanks, Fraser G4BJM
