Re: [Repeater-Builder] GMRS HT recommendation?
Don't know about the F40GT but the Icom IC-F40LT had front panel programming capability, so did its VHF counterpart the IC-F30LT. Versions with high serial numbers (above 3 if memory serves) were wide and narrowband capable. I still have one of each new in the box stowed away along with accessories and software. They were built tough and work fine. Some time ago I scanned the keypad programming guide into .pdf and it's been floating around the internet ever since. If anyone is interested in both of these radios and their accessories software contact me off the reflector. Also, let's not forget there are lots of FPP capable UHF XTS3000's and XTS5000's around today as well that work great on GMRS.

Re: [Repeater-Builder] MTR 2000
You can expect to spend at least $1000 for a used MTR and anywhere from $4000 to $7000 for a new one. 40 watt units are a little cheaper than 100 watt but not by much. I'd recommend looking for something else because the MTR's can be expensive to repair should any repair be needed that requires module replacement. True service manuals are not available (never have been) and even flat rate repair is a little pricey. Also they won't apply flat rate to one that has lightening damage.

Re: [Repeater-Builder] Feedline Connector Sealant Tape

There are more makers now (other than 3M) so we're seeing it more and more available from suppliers.

Re: [Repeater-Builder] Re: Gmrs Repeater
Thanks for that background info. I suppose that's one way to look at it but in my experience a mobile relay station now carries a different definition from the FCC as shown in Part 90.7 for example. They also define a fixed relay station so while at one time the term 'mobile relay station' may have passed as any repeater I wonder if they take a different position today. Gary [EMAIL PROTECTED] wrote: Gary, A mobile relay station is defined as a device that relays mobile traffic (i.e., a repeater). A fixed station is simply a base station, at a fixed location, manually controlled by an operator. This is standard across FCC controlled communications and is not GMRS specific. LMR repeaters are commonly licensed with a station class of FB2, which the FCC designates as mobile relay. A fixed base station would be classified as FB under an FCC license. When a system will have a fixed base operating through a repeater you'll have both FB and FB2 on the license. Hopefully that clears it up.
