Re: HLA-150 Disable amp on tune

Mark Gottlieb <kk2l@...>

You are correct.  The PTT line is not required to operate the HLA-150 since it does have RF sensing. So, the tuning cycle will always activate the amp.  When I use the amp, I want it to key up since that is how I get resonance between the amp and the antenna.  As you probably know, if the amp is not resonant with the antenna, it will automatically go off line.   Excellent amp, BTW.  I was using it on my back deck with the ELAD and was getting 200 watts output on 40m and spot-on 100 watts on 20.
