When using my Texas Star DX-500V wide open, just power on, (no SSB delay or AM/Dial A Watt engaged) radio set to 2.5, dkey so amp output is 100w dkey and swings up, the SWR between the radio and Amp runs a little high via the SWR meter in the radio (stryker 955hp) from 1.7-2.0, but the SWR after the amp is fine, about 1.3-1.5 or so.
Alternatively when I run the amp with the AM/Dial A Watt engaged, SWR between radio and amp is near flat with the radio putting out a 50w deadkey and swings up. Now the funny thing here is if I increase the radio dkey to 4.5 to get 100w dkey out of the amp with the AM/Dial A Watt engaged, the SWR is STILL near flat between the radio and amp!
Next question, is it OK to run the amp with a 4.5w deadkey with the AM/Dial A Watt engaged to get 100w dkey instead of having the AM/Dial A Watt NOT engaged and having these higher SWR's? I know that the AM/Dial A Watt circuit acts as a input pad vs controlling the output so it SHOULD be good to do that, right or wrong?
I've tried swapping out cables of different lengths and got that radio to amp SWR a little lower, it was around a 2.0 across the band and with some different combo of cables has come down some, but never flat with like with the AM/Dial A Watt engaged. Again, AFTER the amp, never an issue, 1.3-1.5 or so.
Thanks for any help!
