Can i make a swing kit for this radio, so i can get a lower deadkey. It is 7 watts and swings to 35 cant get it lower than 7 watts to drive amp????? #15
 

Isn't it possible that the high power pot can be turned
up so high that the low power pot wont allow it to go below 7w?

no high power just vr13 and some pots

Tune L40, L43, L44, and L33 for maximum forward swing on wattmeter.
Adjust AM power(VR13) for no more than 5 watts dead-key - if running a linear amp set at 3 watts dead-key

if you do just leave it and install a swing kit in it it should lower it to 3-5 watt dk....

    Coax question. I just put up a new Sirio monsoon base antenna with 100’ of rg8u coax testing with myMFJ antenna analyzer shows 1.4 swr at 26.965mhz and a 1.1 at 27.405 mhz . When I checked the ohms it’s steady a 30 ohms across the entire bandwidth.
  • @ Geoexplorer69:
    Is 30 ohms worth worrying about in a 100’ run of rg8u ?
