[TenTec] In praise of older technology AM transmit with Ten Tecrigs

[Bob McGraw - K4TAX]

I find that my Omni VII on AM sounds quite good.  Almost as good as the 
retried 1KW BC transmitter with its typical compression and limiting 
equipment in the audio path.  I run the Omni VII at about 20 watts out as 
that is adequate to drive the amp to about 200 watts of carrier or about 800 
watts PEP.

Speaking of amps on AM.  First one should tune the amp to full rated output 
using the  TUNE mode typically at 100 watts and then switch to the AM mode 
on the radio.  DO NOT change any tuning of the amp while in the AM mode. 
You still want the amp tuned for the rated PEP output even though the 
carrier level is 1/4 of that value.  Remember it is a  L  I  N  E  A  R  amp 
and should always be operated and tuned such it stays linear.

As to the Omni VII TX EQ........I don't care for the results.  I prefer to 
choose and use a mike that sounds good and use good mike technique to get 
the best sound.  Nothing external required.

Mike,

Please enlighten us with the settings. What power level do you run on the 
OMNI VII? How about EQ? When I tried it once just recording using a dummy 
load I thought I might need quite different EQ than I run on SSB. Sounded 
muggy. I don't use anything external to the OMNI VII for audio, just a 
microphonium and the unconventional OMNI EQ.
