Kenwood TR-7950. I had one plugged straight into a Yagi @ 5700 ft. for many years & never one burst of IMD. RX was sensitive enough to outperform a co-located 440 RX with GaAsFET preamp (foliage absorption was the likely reason for the difference in performance). The RFPA is able to handle continuous duty but does need a fan. There are also pots on the RFPA board that can get dirty & can cause the output to drop & go spurious. Bob NO6B
Re: [Repeater-Builder] Amateur Mobiles as Repeaters, Part 13
Because we really had little experience in repeaters at the time (late 1970's), our club used a ICOM 22A for many years as the repeater receiver. We just poked around and found a signal that looked like it was useable to control the COR and used the front panel volume and squelch controls for the repeater audio and squelch levels. No one ever noticed we were using a mobile rig for over 15 years. It finally bit the dust after a lightening bolt (we theorized). But for many years, it was as sensitive as any thing I have seen. Not bothered by intermod, etc. Roger W5RD Texas Instruments ARC Murphy, Texas - Original Message - From: Cort Buffington To: Repeater-Builder@yahoogroups.com Sent: Monday, February 25, 2008 10:24 PM Subject: [Repeater-Builder] Amateur Mobiles as Repeaters, Part 13 Guys, We heard from Skipp that the Kenwood TM-271A is very much up to the task of repeater service.

Guys, We heard from Skipp that the Kenwood TM-271A is very much up to the task of repeater service. What about other amateur 2m rigs? Anyone had good long-term success with anything else? Especially shielding, presence of logic and audio signals without butchering the radio (installing an option cable isn't butchering, cutting traces and soldering in here and there is), and a PA that doesn't melt down even when run at much lower power with a fan? 73 DE N0MJS -- Cort Buffington H: +1-785-838-3034 M: +1-785-865-7206
