RE: [Repeater-Builder] HP3551A Service manual
Hi Peter, I had my 3551 failed sometime ago, was intermittent connections in the unit, just cleaned and reseated connectors and IC's, unit has worked fine since? You may want to try it and see if it works.

I have a used HP3551A also, but it recently stopped working. Wonder if anyone had schematics? The manual I found online had everything but no schematics. A good high resolution Jpeg photo of the schematics would be greatly appreciated. Peter Ex. G8DCB. Now resident in FL.USA.
RE: [Repeater-Builder] Motorola Mystery Box
This is a 600 Ohm Delay line used in setting audio delay's on Simulcast paging systems. The delay is in micro seconds. I have used several of these on an old Ameritech 158.100 paging system. This unit goes between the Link receiver or a leased audio telephone line, you set the delay by soldering to the correct post. I hope this helps, Randy WB9VLE From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Scott Overstreet Sent: Monday, June 28, 2010 2:57 PM To: Repeater-Builder@yahoogroups.com Cc: Scott Overstreet Subject: [Repeater-Builder] Motorola Mystery Box Hello All-- In answer to Ted, Eric and others---Yes, I guess it could be a taped delay line --but at telephone audio? I'm saying telephone because of the telco wire attachedWhat do you think the numbers might be?---milli-seconds? seems like that would take a lot of network but then there is a fair amount of space in the box but that would probably add up to a lot of attenuation. First, see the pictures--- as you can see, the box is metal and soldered and the connections are as it came to me. Since my first message, I have ask some questionsit seems that it came this way with a junked 65Mcs Micor that had been in paging service -that's all I know and I'm still mystified-what is it and what was it used for? Maybe its time to make some bench measurements. Many thanks, Scott
RE: [Repeater-Builder] Need Micor crystals for 52.15 RX and 53.15 TX
Hi Steve, For what type of chassis, the exciter is different on the unified chassis. Unless you're using a mobile?
