[TenTec] Re: Tuners

[kh7t@arrl.net (John Buck)]

The reason that many of the "other" radios have built in tuners is so 
that the bipolar amplifiers could be made ot work into a reasonable 3 to 
1 SWR range without folding back power.

Many of these early radios without tuners folded back or distorted with 
SWR of 1.5 or 2 to 1.  Many of the built in tuners are mere band 
flatteners capable of providing the radio only a 3 to 1 or so capability 
which is no better than the robust TenTec amplifier design does without 
a tuner.

The TenTec design approach of designing a Crunch proof 100 watt 
amplifier with at least a 3 to 1 full power capability will make it easy 
to use many antennas over the whole band without tuner and without 
blowing up the radio.
