Handhelds can *NOT* be expected to give decent coverage, especially on 2M. First, you have the lower power level. Then you have an antenna that is typically 5-10dB of LOSS. Plus there's no good groundplane for it. Then you get into multipath and so on. We tell people that the repeater is not designed for portable coverage, and cannot economically be made so. And DO NOT, under ANY circumstances, try to repeat another 2M freq onto a 2M repeater input!!! That's just asking for trouble!

Look for a GM300 as opposed to a Maxtrac. The GMs have a channel steering option that can be enabled in the RSS and by grounding selected pins in the 16-pin jack on the back you can binary select 8 or 9 (I think) channels... using three or four bits in a binary pattern. The 7K lets you output a 6-bit binary number to 6 pins on the 7K connector, the manual shows 5 on a TS32, the web page at http://www.scomcontrollers.com/tips/7k_ts64_motorola2.html shows how I set up a TS64 (uses 6 bits), you could set up a crossband repeater with the PL board in it locked to one tone (or DPL code), and use touchtone commands on the 7K to steer the 2m GM300 to the channel you wanted to talk on. Chapter 10 in the 7K manual has all the details on the (PW)03xx command. So take a UHF Maxtrac or GM300 and a high band GM300 and get a few connector parts from DigiKey...

And these pins are gold plated! More info on the 16-pin connector is at http://www.repeater-builder.com/maxtrac/maxtrac-option-plug.html So print out the two articles, get a couple of connector bodies, a bunch of pins, an SCom 7K and using the CTCSS tone select outputs on and wire yourself up a crossband repeat cable with a Scom 7K in the middle. Connect PLF1 through PLF3 to the channel steering lines in the GM300. Program the startup macro to select channel 1 in the GM, and program the GM so channel 1, 2 and 3 are infrequently used simplex channels (like 146.535, 146.565 and 146.595) so you have places to test without bothering anybody and 4-7 as your local 2m repeaters.

Yeah, but look at the mapping. You don't get 16 selections. If I remember correctly when the high order bit goes on the radio ignores the other three. So you get 0-7 plus 1.

RE: [Repeater-Builder] Re: Remote Base/Repeater Question From a Newbie
I agree, the GM300 has channel steering. I looked in the manual, and I was wrong about the number of channels. Five bits on the accessory connector are programmable, the first four let you select channels 1-16 using straight binary values of 0-15, however if you make bit 5 active then the first 4 are ignored and you go to channel 32. You'd think that if bit three was on (giving the decimal value of 8) and you flipped bit 5 that you'd get channel 24 (i.e. 16+8), but no we can't make it that easy and have straight 5-bit binary and have all 32 channels in the radio selectable... If you flip bit five, you go to channel 32. Period. So where I said: % If I remember correctly when the high order bit goes on % the radio ignores the other three. So you get 0-7 plus 1. I should have said the radio ignores the other four. So you get 17 logic states using binary 0-15 plus one more.

Kerry, If you decide to go with the PAC-RT, let me know. I have a VHF unit right now in my shack - it's on 154.920, IIRC. We can talk. :-) 73 de Mark - N9WYS -Original Message- From: Repeater-Builder@yahoogroups.com On Behalf Of kdf9511 I think you may be right. I did a bunch more research on this last night and after looking into the fact that I want to also build a irlp/echolnk node this my be the best way to go. Looks like something like a Motorola PAC-PL/PAC-RT is what I need. I want to find something a bit newer though that doesn't take crystals. Kerry KE5OFO
