I have a tendency to put this in the back of my mind and forget about it until I’m on the air – but there is one change that I need to make to the Rover… Switching. I often look at the BNC port on the radio as a quick swap, but the fact of the matter is that it’s additional wear and tear on equipment that I don’t need to have happen, not to mention it can take me upwards of a minute if I’m fumbling around with mixed up cables, and switching is a very simple fix that I keep putting off. The way I have my equipment setup, I really only need the switching on the IF side, so it only needs to be able to handle 144/432 mhz, meaning I don’t need anything special – all of the antennas are directly wired to the transverters, so why I haven’t done this before now is beyond me.
Easy, quick fix that’s going to save a good bit of time and effort.
Ebay has used multi-purpose RF switches. Anything from 4 position to 8 position is common and they typically cost $50 – $150. They are rated for 10GHZ+, so even the used ones will work fine at UHF. Look for 12V to make integration easier. Then consider a rotary switch with the same number of positions (+1 extra position). You send the 12V through the rotary switch to the different terminals of the relay. Once you do this, you won’t believe how nice running the bands can be – KF2MR
