RAM - Repeaters & Technical

10/24/2024

This episode of the Ham Radio Workbench podcast is well worth a listen. Normally they go on and on about screwdrivers and soldering irons but one of the regular hosts lives in South Carolina and was in the path of Hurricane Helene and got walloped. (the power company doesn’t expect they will have power to him before Christmas! Luckily he had solar and batteries).

Find out what works and doesn’t work in a disaster and why you want to have a radio with dual receive (spend the extra $$).

You can listen to the local repeater (N2GE) at https://www.broadcastify.com/listen/feed/42258.

(I’m expecting to be deployed to his county next week to help with recovery. )

What are the chances someone has a GPIB- USB adapter laying around that they aren't using that they like to sell us cheap? We have a couple of pieces of test equipment with GPIB (General Purpose Interface Bus aka IEEE 488) outputs and being able to control them from a PC would be a great thing especially as one has a failing CRT. A GPIB connector looks like the old Centronics parallel printer connector (but with 24 pins instead of 36) so you might have one and not even realize what it is!

What is it? A silver plated brass pipe that forms part of the adjustable 1/4 wave stub in a duplexer. Why am I showing it to you? We need to put new threads on the end; anyone got a 3/8-40 die we can borrow for an hour? (Yup its an odd size not found in your typical consumer T&D set).

For bonus points we need a replacement nut thingy (sort of looks like a collet) that screws onto the pipe to clamp down the invar rod that passes through it. We have the locking nut off the top but the big part self destructed (all brass so it's easy to work and also easy to OVERwork - IYKYK). Any ideas as to a source or even the correct name? And yes I've checked McMaster-Carr.

I can't afford it and don't know what I would do with it but I want it. I really want it.

Attempting to refurbish some older duplexers. Starting by polishing up the lower half of the resonator and the fingerstock that connects it to the upper half of the resonator. You should be able to see a difference between the original units and polished ones

https://www.ebay.ca/itm/315318674624?itmmeta=01J11BZMB0733HFFDNCC2JGHHB&hash=item496a7524c0:g:vz0AAOSwcGBl9D18&itmprp=enc%3AAQAJAAAA4AX8xGtMDgyOaZk4X9SWa9q1MaQFs17nno2cKZQDGOI8OxBV5B0P%2FRcokt6oDYiJWR%2BPHDSqwI%2BbBfcCUC1O7i%2BwEnwTvo--D%2BPKVx4RQ%2Fqk7AOcK9DD3E2OICiih6DibvP4v6tnu5fulV8UkmRSkL28W20BPP%2BI7CaEXK0XuTDGUoeyp548cssR6vnmDQyDLDBzJUUE0Hul5J2bDqbzGFqcQfavJuX357TIJUURet5sZjqwHgSbnvXei8OMYgSD7U%2BlxM7JS1LmLbVyKZxPTMyGzarbR4VGPuKhXVTAZpLo%7Ctkp%3ABk9SR9zF_quIZA

The SPA525G is a really nice unit as it can handle multiple lines so you could be connected to BOTH HamShackHotlLine and the WAN system at the same time. Also it has WIFI built in so you can just plug it into power and connect wirelessly. It uses 5VDC so if you add a 12VDC to 5VDC step down module you can pack it in your Go-Box and run it on the battery.
