Re: Pyramid SVR-200 Repeaters (extenders) on Ebay
There's a semi-regular (great) ebay deal on surplus Pyramid UHF SVR-200U Mobile Repeaters... aka "extender". Just a little background information to potential buyers. The mentioned surplus units are older vintage with slightly different electronics. The rf section is nothing like the current version. But the logic jumper functions and setup are similar. Staying in the as- received 465 MHz range should not require a realignment of the rf module/section if it makes the expected spec. The SVR-200U can be moved into the 440-450 Amateur Band using the earlier version software. Because the rf-module is a different animal you should get your hands on a copy of the now out-of-print (unavailable) early SVR-200 Manual. I pulled some of my Pyramid Dealer "strings" and found a copy of the early rf module circuit diagram and alignment step, which is just the ticket to have. Yes I will make pdf file copies available as time allows. Otherwise software and the current SVR-200 Service Manual can be found for free at/on the Pyramid Web Site. Kind of nifty to have an extender on your amateur or commercial mobile. In-band repeat is quite possible/easy with the proper considerations for layout, rf-protection/isolation and operation. Feel free to email me direct if you need more information... cheers, skipp skipp025 at yahoo.com www.radiowrench.com
