[1000mp] Re: Mark V Field Power Output Mod

[Mike MacDonald]

In a mail from Chen, W7AY {concerning the 60M tcxo question} he
sent a linked page 5 from Yaesu UK on the Field. Check the power
output spec:

My original post below has stimulated allot of controversy and posts. I
stand by what I already said:

.....I've tested the rig extensively at 175 watts on CW and RTTY and have
suffered no component failures, overheating, etc. and no transmit spectral
degradation. Of course like all mods. make it at your own risk.....

I look at it this way. In the original spirit of ham radio I'm not afraid to
open up my modern expensive rice box, to experiment and modify. In my
original post I never mentioned operating my V Field at 200 watts but it did
hold up very well with no overheating etc. at 175 watts on CW and RTTY, as
an experiment. Why did it hold up so well? It's because the rig is better
engineered and has better specs. then advertised and a certain amount of
"appliance operator" headroom is built in.

Am I stressing the rig? Maybe so but if it blows up I'll fix it and/or buy
another one. One ham posted in response to my original post, to paraphrase,
"Real Ham's understand how electronics work and don't turn up the power on
their rig". I say "Real Ham's" are not afraid to experiment.

In any event, in my day to day operations I never run my V Field above 125
watts. I originally tweaked up the power output because from the factory my
V Field only put out 90 watts on 160 meters and I needed 125 watts to drive
my old linear to 800 watts.
