After reading your post Chickenhouse I have to say....that's more or less what I expected.
I thought to myself...I just cant be bothered with all the hassle...knowing my old and trusty interface/intercom would prob also need changing as plugs connector could be different.
That and lots of other niggles was enough to send me AWOL.
P.S. I had a spare 25khz A20 for my aircraft...I kept that...still works a treat as an airband receiver when I want to have a listen...just as sensitive as ever on an external antenna...obviously cant get the new in between frequency's but in my area nobody is using them far as I know.
