Sent you an e-mail a bit ago but not sure if you received it because I don't see it in my 'sent' file. I'll briefly outline it for you...I'm the one with the black BMW R1150RT in case you don't remember the name. I have mounted a Yaesu FT - 8800 on my bike. I have no intercom system. I currently use the radio's stock microphone. I'm in need of an interface that could connect from the radio's control head to a J & M headset with a PTT button...or...a complete system with a PTT button but without an interface. I contacted the people at Kennedy Technologies (cellset.com) and they said they couldn't help me and referred me to M. A. R. C. (BTW...I've joined MARC recently but not sure if Jerry Irwin has sent you the money yet). The microphone connection is a modular (phone type) DIN plug. Unfortunately, I've not been successful in locating anyone who has a cable like I'm in need of and believe it or not, I'm not very adept at making electronic parts myself and would much rather pay someone to construct it for me or buy something commercially available...hence the reason for this e-mail to you. Mitch, Katy, TX. ======================================= Mitch, I am sorry to say that I know nothing about the Yaesu FT-8800 ham radio or the BMW R1150RT, so am taking the liberty to put your request for information out on the MARC List. That is what it is for to be used for anyway and is the best way I can think of to get you going in time for the TX MS150. I also sent your email to Jim of Lake Elisnore CA because he has a BMW and has done his own installation on it, so right now he may be the best bet to help you. Please be sure to post your communications on the MARC Web Site, because we all learn from these experiences. Ray KD6FHN Irvine, CA ==================== I have a gold wing, but have used both an 8800 and an 8100 (currently) on my bike. John, Los Angeles, CA ========================== Mitch, The Yaesu FT-8800 appears to be the current replacement for the FT-7100m which I have as a base station. As best I can tell from the Yaesu literature, the FT-8800 uses the MH-48 microphone which has a *6-pin* modular plug. And therein lies the problem...! When I got my Heil Traveler headset, one of the adapter cord options is the "Yaesu Modular". I bought that adapter and a Kenwood modular (for my TM-D700A) and was a happy camper -- well, at least till I got home and tried to connect the headset to the radio. OOPSIE -- the cable is *8-pin* (RJ-45 type) -- doesn't fit too well in a *6-pin* jack. I called Heil -- if anyone would know about this 6-pin interface, it would be Heil. According to Heil, the problem is that the FT-8800's MIC connection is MULTIPLEXED. Heil has a special adapter for the FT-100 which uses the 6-pin but it only fits certain Heil Mics and the Traveler isn't one of them...! They finally gave up trying to get this unusual MIC wiring to work with their gear (except the FT-100 special). Quite honestly, perhaps the best -- and most expedient thing to do, would be to get you hands on a Kenwood HT. I don't know if any of the TX hams used 5-watt radios last year; if so, with a decent antenna properly grounded to the Beemer's frame, you should have an adequate setup. J&M used to make a simple plug 'n play Kenwood *FRS* cable assembly with PTT (I think it was RHD-60) that works perfectly with the Kenwood radios and the J&M headset with the 5-pin lower cable (Goldwing type -- I think it's a ZB). I just looked at the J&M website and don't see it now...! Apparently, J&M's new INTEGRATOR IV system replaces that simple cord -- since they show a JMSR-AC16 interface cable for the Kenwood FRS. But that darn black box is $450 WITHOUT the adapter cables. You might call J&M to see if they still have some of those older cable assemblies in stock. CAUTION -- do NOT even whisper the word HAM around J&M -- John Lazzeroni, president of J&M has an attitude about hams...! Just refer to the Kenwood Free-Talk FRS radio...! MARC member Charles KF6TXI has an old J&M Kenwood FRS cable assembly. I don't know if he would be willing to sell you his since he now has the Kennedy interfacing his Kenwood TM-D700A. I've Bcc him on this email. The other choice to buy would be a Kenwood TM-D700A. Yeah, it's a bunch of $$$ but we (Ray and I) have much experience with the Kenwoods and Kennedy makes a plug and play black box to interface that radio. UNKNOWN to be is whether it could be "stand-alone" or if it would even interface with the Beemer. Chuck, Santa Ana, CA MARC GPS/APRS Coordinator ======================================== Mitch, The FRS setup that I have is specific to the Kenwood FRS and Kenwood Ht's it will not work on the Yaesu. Charles, Tustin CA. =============================== Mitch, I've wired my 8100/8900 both through a Kennedy set (GW Intercom etc.) and independently - which seems to suit your needs. And I have a J&M headset in my helmet as well.I have all my wiring diagrams etc and will do what I can to help you. One of the challenges with Yaesu is the need to integrate a 27k ohm resistor in the mic/ptt circuit. But, again, I've done that, so I can probably help you out if no one else does. Good luck, John, Los Angeles, CA.
Ray, I would like to ask you question: |
