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

I bought a Motorola R2600C for $600 and then about a week later picked up a Motorola R2550 with tracking generator for $400. I already have a Rigol DSA815TG spectrum analyzer that I use for filter

Could you upload some photos of it?

Ken, You are likely right but if I had the part number off the board I could confirm. There were some 100 watt mid band boards as well. The coils look different from the UHF ones I have here. Ken

Quintron QT-6700 (UHF) was 90 watts.I have a spare here and his board looks nothing like the one I

Need the part number on the other side. Post a pic of the other side. Looks like a Possible mid band board. Ken Pearce N4KCD Commerce Township, MI

Just looking at it, especially the LP filter, I'd say UHF...lots of strip line used Chris WB5ITT [email protected]> wrote:

I have this PA and it is labeled “100W PA”. However I cannot find the datasheet for the transistors. Motorola SRF2604. any ideas what the range for this is? drive needed?

Looked it up in a Nemal Electronics Catalog, and you remembered correctly, Jeff. Both cables are identical except for the jacket on RG393 is -70 to +200 degree C fluorinated ethylene propylene (FEP)
