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!

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.

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.

TM-241 a were not designed as a repeater use reciever or has the capability to hold XMIT until the RF Module SAV 217 or was it SAV 218 ?? takes a dive, no fan BTW only good for 5 watt packet radio or sell to a newbie ham .

Re: [Repeater-Builder] TM-241A audio to external tone decoder
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.

[Repeater-Builder] TM-241A audio to external tone decoder
I am wanting to temporarily use a Kenwood TM-241A radio at a repeater site... not for a repeater receiver but for something fairly "mission critical". I fed the audio output available at the mic connector to a TS-32P and it seemed to decode fine at first. I have now found it decodes signals from some radios and not from others. Not sure if the audio level is borderline (too low) or if the audio from that point may be after a high pass filter in the radio or what??? Any hints? 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 Yahoo!
