Mike I have a modified Syntorx for two meters. You may want to take a look at Piex.com. They are the people I got my mod kit from and it worked well. I think they could have made provisions for a control head and it would have been much nicer. They also advertise it will go to 220.0Mhz and I agree. The mod kit is very nice and well thought out. If I can answer particular questions don't hesitate to ask. 73's de Tom MAnning, AF4UG - Original Message - From: "Mike Morris" <[EMAIL PROTECTED]> To: Sent: Sunday, April 02, 2006 6:20 PM Subject: Re: [Repeater-Builder] Syntor X conversion to 222 as a user radio? > At 02:25 PM 04/02/06, you wrote: >>I'm searching various yahoo groups looking to see if anybody has ever >>modified a Syntor X up to the 222 MHz band...

I did the math on a Motrac a long time ago, and actually moved a 172mhz Motran (then had a serial tag made up that read U43.5MSN-3190AK) Basically I converted the receiver LO multiplier 75-to-150MHz doubler into a tripler, and ordered rocks for 149MHz receive channels from a local cheap rock chipper. I wasn't going to spend good $ on a experimental project. The front end mod was similar to Kevin's Micor-receiver-to-220 mods. The transmitter got the same doubler-to-tripler mod and the PA deck was actually pretty easy... each tuned circuit had a coil, fixed cap and trimmer cap in parallel. By diking out the fixed cap it all tuned right up.Not exactly the right L-C ratios, but it was a proof-of-concept idea. A 149.150 CAP or MARS (I forget which) channel element with a cheap crystal that had drifted low beyond use was able to be tweaked to 149.0 and it landed me on 223.5 The finals were inefficient enough at 220 that they didn't need any neutralization... I was seeing a clean 19-20 watts out. I had the radio working on the local 223.94 and 224.94 repeaters, and on 223.5MHz simplex. It lasted about a year before it got replaced with a Midland 13-509... 12 channels in a smaller box. Then a 13-513. Then a trunk mounted 13-513 with 11 memory channels (DIP switches back in the radio) and one VFO channel via a homebrew control head. Mike WA6ILQ Yahoo!
