This is the first I've heard of anyone installing cooling fans in the Omni 6.
Actually, this wasn't an uncommon topic a few years back. Personally,
I found that my PBT settings were shifted dramatically during cw
contesting due to internal heat buildup. I used an external fan
blowing on the rear heatsink which seemed to help, but the internal
cooling fan always seemed a good solution to me.
I find that operating my Omni VI in CW contests a fan on the PA heat
sink is necessary. My Kenwood TS-440 has a built-in fan with temperature
controlled speed, or at least duty cycle. The TS-440 receiver
performance in contest conditions does not compare to the Omni VI
though. I wish Ten-Tec would have included a built in fan. I have never
tried, or thought that I needed, a fan to ventilate the insides of the
Omni VI though.
Okay now you can flame me for saying that a JA rig has a usefull feature
that is not in a Ten-Tec.
