Not for high voltage, but for fire alarm cabling on utility poles. I had a Riser Bond TDR that I used for fault location.? A long time ago I was asked to find a fault in a municipal cable that was

Quintron made a lot of equipment for the 72-75Mhz linking band for paging. Joe, K1ike

Mornin' John, In the MTR2000, the GPIO pins on J5, the 96-pin System Connector only connect to J1 and J2, the Option slots in the cardcage.? The System Controller is at J3.? To use those pins

Attached is some information on the DB212 antennas. Perhaps this will help. This was factory info from a DB212-2 that was tuned to 47.14 MHz. 73 Joe WB4HIS Sent: Tuesday, April 8, 2025

It definitely looks like a Quintron constructed board.? The white label with the writing on it looks like how they identified boards. The date code may be 1989?? I think that was before they were

Anything with an SRF part number is usually a special-production or binned version of a regular MRF part, but rarely were cross-references (if they existed) published. That said, given the amount of

Chris, I'm trying to program channel steering in the RSS using GPIO pins on the 96-pin connector without any optional cards. That section of the RSS isn't very straightforward to me. 73 -de "Curly"

The Motorola 2600 series is hard to beat... And can be found reasonably priced if you are patient. [email protected]> wrote:

Mike, This is a Windows program, but I think it's a lot of what you want and you can choose the hardware SATSAGEN ( https://www.albfer.com/en/2020/02/21/satsagen-2/ ) Steve N4IRS

Well here's an idea, put 12 volts to it, put a service monitor or signal generator into it, broadband watt meter on the output and sweep it and see where you get a peak in RF out driving it with say

Here is a pic of the only numbers I see on the board.

does anyone have a programming lead for a kyodo kg510 or schematic of one

Alex: Thank you for these pictures. This is very helpful information. I have a Johanson catalog and tried to match the capacitors at least in physical size.? It did occur to me the capacitor values

Anyone have experience using a TDR to locate an underground fault for high voltage ? There's a PUD in central Washing that can't appear to fix an outage for the past three weeks or so. It's affecting

I think you guys figured it out. It is 0.43 outside diameter and looking up RG-225/U yields the same cable that I have. The cable I have has absolutely no markings on it. The only reason I know it was
