Re: [Repeater-Builder] TM-241A audio to external tone decoder
Yes, I know Mark. I don't need it to transmit, just monitor a frequency and only for a few weeks. Fortunately I'm at a really quiet site so the receiver doesn't get crunched. Getting tone decode to work reasonably well was cured by using speaker audio... guess this is one of those typical ham rigs that doesn't filter out the tones from the RX audio. Come to think of it I had noticed while using it at home that I could hear tones from some people sneaking through that RX. Paul, N1BUG On Sunday 07 August 2005 10:26 pm, Mark A.

Re: [Repeater-Builder] TM-241A audio to external tone decoder
Thanks Paul. Just getting a chance to catch up on mail here. Speaker audio does seem to work better in this case, which surprises me. Whatever works! Thanks for the help.

I am on my way back to the site to mess with it some more but will check back with email in a couple of hours. Paul, N1BUG That audio is after the high-pass filtering that specifically filters out CTCSS. The easiest thing to find would be to go to the high side of the volume control pot (not the wiper), and see how that works. It's most likely raw discriminator audio. -- Jim Barbour WD8CHL Yahoo!

We had similar difficulties with a 241 and an external tone board using the audio from the mic connector. We switched to using the ext. speaker jack for an audio connection and it worked much better.
