Actually, I don't think .49 went on until the late 80s. I forget where they were before that. Maybe it wasn't anywhere and 146.790 was the only Washington (PA) repeater. Joe M.

I think Sam was originally on 145.25 in the early 1980s and moved after a short time to 145.49 to get away from the cable TV leakage crud. Wow, what a workout for the memory banks! I moved out of the Washington area to Northern Virginia in the mid-1980s but traveled back regularly until about 1990 when I moved to Minnesota for E. F. Johnson. At the Irving, TX Hamfest today there was a guy with a box full of E. F. Johnson manuals -- sure brought back the memories! 73, -- Tad Danley, K3TD Yahoo!

Re: [Repeater-Builder] Re: 440 - 450 Low in High Out Repeaters
Yep. You're right. I just couldn't remember where he was before. Your post brought it all back, and that's exactly why he moved in 1987. He's still on .49 and still under the same call. In fact, of the three repeaters you mentioned, they are all still on the air from the same or similar locations. Well, back into the woodwork. :-) 73, Joe M.

Re: [Repeater-Builder] Re: 440 - 450 Low in High Out Repeaters
Ahem ... My first commercial 2 meter mobile/base was a Motorola FMTRU-5V ... 7 watts out using a 2E26 as a final. My first repeater was a GE Pre-Prog on the 449 MHz band - used a 2C39 driving a 2C39 as the final. Alhough I never used one, I do remember when the GLB (Good Luck Buddy) synthesizer came out and was added to the commercial radios. 73, Neil - WA6KLA Tad Danley wrote: Neil McKie wrote: skipp025 wrote: ... snip ...

Re: [Repeater-Builder] Re: 440 - 450 Low in High Out Repeaters
I was not mention anything about the performance of the Micor as a repeater, only as a reference of using same crystal for TXRX, yes i am aware fo the offset crystal, normally this was 11.7+5.0 ( 16.7 Mhz.) so the TX will above of the RX.. Juan - Mensaje original - De: skipp025 Hello Sailors, Regarding Juan's comment below. The micor mobile makes a great repeater when you keep the in cabinet desense under control. Cutting the channel element crystal for the proper injection and tuning will determin high-side/low-side tx-rx. Changing the offset crystal will modify the original motorhead 5 or 3MHz tx-rx spacing. If you buy a poor quality channel element crystal, both the receive and transmit frequencies will drift as one. We used to call these "VFO Repeaters". Cheers Skipp Yahoo!

[Repeater-Builder] Re: 440 - 450 Low in High Out Repeaters
Hello Sailors, As I replied direct to John, the trend setters statement was made tongue in cheek. His reasons for their bandplan make sense in rural areas. When you get into large metro areas, all the rules go out the window at busy mountain tops and repeater sites. You just can't hide from that nearby 1/4kw paging transmitter... Receiver distribution and transmit combiner systems become a lot of science, experience, budget management and magic with mirrors. Regarding Juan's comment below.
