Bit of IC-905 ATV fun :-)
Audio squelch does not work on ATV, it just mutes the audio completely.
Also screen flickers sometimes when on ATV mode..
Couple of bugs to fix @UK_ICOM
Been measuring toroid inductances to work out why my 9:1 UNUN has not been working well. Interesting results so have now constructed a totally new version using FT 240/43 toroid which has a much greater Al factor.
