It's been standard for quite a long time. I had to find a .206 jack to build an interface box to connect my Telex ANC headset to the TR7, but found a new stock jack on that e-place for reasonable money. Better than cutting the plug off an expensive headset. The headphone jack is standard 1/4" stereo, and nowdays the aircraft headsets can be operated mono or stereo. I was thinking of wiring mine to have a spotting RX in one ear and the main RX in another, but that could get confusing... :) 73 -Jim NU0C ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

Re: [Drakelist] Microphone Jack Trivia
Actually, a good question and one that I've never seen a good explanation for. A few years ago, I bought a new aviation headset to use with my station and guess what? It had a 1/4 inch plug for either the mic or headphone (don't recall which) and a .207 Drake-like plug on the other pair. Apparently that's been standardized over the years so any headset can plug into any aircraft radio (at least for private planes). Whether or not that started before Drake began using the smaller plug, I don't know. 73, K8AC - Original Message - From: Richard Bell To: drakelist@zerobeat.net Sent: Sunday, August 17, 2008 4:08 PM Subject: [Drakelist] Microphone Jack Trivia I don't recall seeing this question asked but why did the Drake Co. choose to use a smaller mic jack on the T-4 line?

Re: [Drakelist] Microphone Jack Trivia
Do you recall the grand old days of movie serials when they had mics plugged into the headphone jacks of SX-42s and similar receivers. They could work MARS (the planet) anytime they wanted with no QRM, QSB or TVI! They could even work mobile rigs in cars that only had a microphone and 96" whip, but no control head or radio in sight. Sometimes, they forgot to use an antenna. Must have been one of those early mobiles where the antenna was under the running board. I'll bet they got reports of dirty signals!

Re: [Drakelist] Microphone Jack Trivia
Hi, It's generally thought that the reason was so you wouldn't plug the mic into the headfone or key jack & vice versa. Damage could occur to the mic element in some cases. 73, Al, W8UT New Bern, NC www.boatanchors.org www.hammarlund.info "there is nothing -absolutely nothing- half as much worth doing as simply messing about in boats."

[Drakelist] T-4X Mic Jack
Good Morning All, I just finished reading about the whys & wherefores of Drake's decision to use a slightly smaller phone jack as the mic terminal in their T-4 series of transmitters... I had no idea of this until I tried plugging a "regular" 1/4" mic plug into the jack. Looking in behind the front of the chassis, I decided that I could safely bore out the opening of the jack to a more user-friendly (i.e. common) 1/4" barrel, and I proceeded to do just that utilizing the "B.F.A.I" concept (a.k.a. "Brute Force And Ignorance", Hi Hi). I proceeded slowly, and surely enough, it ended successfully. Now I just have to be careful as to which plug I insert into which jack, as VE3EFJ warns... I wonder if anyone else reading this has done the very same thing, but for reasons unknown, will not "...go public" with a pronouncement...?! ~73~ Eddy VE3CUI - VE3XZ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
