[Fox_Tango] Yaesu FT-101's

[Brian Carling]

Actually it's possible to safely run up to about 70 watts input on AM provided you 
have the fan accessory running, AND provided it is on!

Recommended from the factory is 40 watts input, but...

The FT-101 series are quite capable of 260 watts p.e.p. and I ran one at 240 to 
260 watts input on CW for many years with no trouble.

Overmodulation would not necessarily destroy the finals either - just make the rig 
sound awful!

For AM you need 25% of the peak power for your carrier setting

The FT-101 series work quite well on AM and you will have a blast with it on 3880, 
7290 and 29100 kHz areas.

Give it a try!
