More Radios

Hi All,

I got another chance to play with the radios. This time I decided that I would see if I can connect to the Mt Bindo Repeater using one of the radios that have been very generously passed onto me. Looking through the ones I had it was looking like I was going to have to give one of the two Icom IC-22S units that I have a go. The only problem is that I was told one of them doesn't work and I couldn't remember which one that was. So it was time to start experimenting.

The first problem I had was that on the end of the power cable away from the radio there was a plug that looked like this:

Now I have never seen a plug like that and couldn't find a socket here for it to plug into. So I cut it off with about 4 inches of cord still attached so that when I find a socket for it I can still use this. Once that was sorted and connected up to the 12v power supply I connected up the older looking dustier unit that had some of the programmed frequencies written on paper taped to the top of it. At this point I fired it up and tried to call into Mt Bindo; which didn't work. However everything appeared to work and when the squelch is turned down you can hear static so I think this is the good one. I might have to read up on the instruction book to see if I can work out how to make it trigger the repeater and I'll also check that the crystal is in there and is the right one and looks like it works. Otherwise I might order a new one that I know will work to try and get this working.

As to the future of the IC-22S units. Well I'm not sure, if this one turns out to work well it will probably stay here as my base station VHF transceiver, and possibly if I get into some of the other things that get done on VHF, particularly those that are connected to a computer I will probably use one of these as the frequency is fairly rigidly set.

On the HF front I also tried the Yaesu FT-7 transceiver that I have, however while it seems to receive fine it doesn't transmit when the PTT button is pressed so that is something that will warrant further investigation.

As a final note, if anyone is interested here is a photo of my operating station. I know that there are a number of things that are less than ideal, however this is my attempt based on the compromises I have to make at the moment.

I'll be back soon.
