If I remember, I tapped the high side of the volume pot for a TS-32. Encode went in following the instructions for the version of the SS-32 that was made for portables and small radios of the late 70-s/early 80's...it's out there somewhere...and I did find COS somewhere too...probably with help from the old ACC notes. Now I have a 4A from my dad's estate I may see if I can do the same thing with...

Hey If you want a simple kit the partical Basic controller kit is very reasonable. www.ics-ctrl.com 73 Brian ka9pmm skipp025 wrote: > > > Hi Fred, > > It would probably be more accurate to call it a cross band > port hole or window unless both bands are full repeaters with > audio and COS/COR working together. > > It's been done many times with both mobiles and portables > with an example like the Motorola Radius/Maxtrac Radios wired > "back to back". > > One of the group members here wired two HT (portables) into > a repeater, which could just as easily be converted to a > cross-band port hole (window).

[Repeater-Builder] Re: Homebrew low power Repeater
Hi Fred, It would probably be more accurate to call it a cross band port hole or window unless both bands are full repeaters with audio and COS/COR working together. It's been done many times with both mobiles and portables with an example like the Motorola Radius/Maxtrac Radios wired "back to back". One of the group members here wired two HT (portables) into a repeater, which could just as easily be converted to a cross-band port hole (window). I've seen that project twice at the Dayton Hamvention and it looks pretty nice. I've wired the Icom 2at and 02at (and higher band) portables into both cross-band and full repeater operation. The hardest task is dealing with (finding) valid receive signal logic from the receiver... used to provide the PTT (transmit) direct or through some type of controller circuit. Some people use voice detection to make/provide a COS/COR logic, some folks "tack on" a CTCSS (PL) Decoder and some actually open the radio to find a usable "tap point" in the receiver circuit. Depending on how tricky (and how much money) you want to invest in the package... voice operation can work, or it can be quirky, jerky and a real pain to deal with. An Icom 2AT "probably blows" enough CTCSS tone through the regular speaker audio output where you could easily tack a decent CTCSS Decoder on for decent full CTCSS Operation. No kits yet... but I'm thinking about it... cheers, skipp www.radiowrench.com/sonic > "Fred" wrote: > Hello: > I would like to build a low power 5 watt cross-band > repeater for 2m/440 use.

Hello:Dave ypur proyet is a verry good idea, I will like to have more information on the way it put together, i like to know it be posible to make i wiht tow hi power mobiles radios it be great. thanks for the atencion to this meassge.
