The TX mod only affects the sound passed thru the transmitter but the RX mod uses a point in the audio chain that is before the squelch so when no one is transmitting you will have only noise. 73 de SA0AZT, Mattias Hello John,

My McMicro could do with a bit more treble. what does this modification actually do? My McMicro could do with a bit more treble.

Welcome to the world of radio and electronics! I am glad to hear that you found my website. The schematic you'r looking for is on the very site you posted, more specific, this image <a href="http://www.eqso.org/Interface-Circuits-files/01.jpg" target="_blank" rel="nofollow">http://www.eqso.org/Interface-Circuits-files/01.jpg</a>. The benefits of the isolated interface is that you protect your radio against voltage spikes etc if something goes wrong. I've never done this and nothing has never happened but this is up to the maker to decide. I hope this helps a bit, I'd be happy to help more if you get stuck! Best regards and 73's Mattias, SA0AZT Hello!

I am an information security specialist by profession. was browsing the net for some good simple echo-link interface design and came across your page. Would much appreciate if you could share the schematic. have gone through the schematics @ http://www.eqso.org/faq/ptt-Interface-Circuits.htm was wondering the benefits of the ISOLATED INTERFACE at the above site, the rigs I have are all 2m TM271a, IC2200H and VX7R and a PIII computer dedicated for echolink at my QTH with com ports 73's AP2CJ would much appreciate your advise and help.
