I got the second T41 v12 with SW ver66.4 with amplifier operating today.? Both are acting the same, oscillations around 40MHz at several watts when PTT is engaged.? With the oscillation, I was still able to do the TX IQ null.? I am stumped.? I don't have a very accurate way to measure power yet; using a 50MHz TBS1052B tek scope and an HP363 kit.
