Thanks for drawing of so called "Ring modulator". As this circuit is very old, it is not used in the transmitters in awaydays. And it is not helpful for readers on Wikipedia because it doesn't explain the principle of the "Ring modulator".

However, to maintain it as an archive, please re-watch the actual schematic of the transerver, we will be happy if you re-draw it. EX. "TS-520" produced by Trio/Kenwood inc. was very famous. We can find it easily by searching images on internet.

PSN method including "Webber method" will be more helpful for many users. --Dougen2015（会話） 2016年5月7日 (土) 12:38 (UTC)
