Doesn't anyone make 23cm radios these days??

I don't need other bands, so think I will probably be looking at getting a transverter to get on this band.

Need to keep away from Pete M3PHP. (Just Kidding Pete).

On the subject of Ghz bands, does anyone know of any radios either black box or kits that conform to Ofcom IR2028 (http://www.ofcom.org.uk/radiocomms/ifi/tech/interface_req/ir2028.pdf) spec. These would enable an M3/M6 to get onto the 10Ghz band.

I think Icom does a IC-910 or something that has a 23cm module, and so does the TS-2000.

Don't know of any higher band stuff. I had a similar conversation with an M6 the other day regarding 70MHz since there's not much available commercially for that.

Go onto ebay and try and fun muxon handhelds, they are from Hong Kong and do something like 68Mhz to 174Mhz, loads of M6/M3s and other classess are using them since they are not converted PMR. They work very well on 70Mhz, there is a group using them in our area (North Surrey).

James, I meant 1.2 Ghz & 10Ghz, not 433Mhz, sorry mate.

Most transverters use 144MHz as the I.F.

Homebrewing is usually the order of the day here, you may find some kits if you look hard or join a club, best place to start would be a microwave club.

Listen to 144.500 for ATV talkback, break in and start asking questions :)

Hi Paul,

Unless you've got a local 23cm repeater and a fair bit of activity I'd give 23cm FM a swerve for the time being, as I think it may end in a load of frustration. You'll be better off with cw/ssb, and the cheapest way to go is to use a 2m or 70cm multi-mode with a transverter. Microwave modules transverters and others often appear on feeBay but are getting a bit long in the tooth now. If you're up from some home construction then the kits from Mini-Kits in Oz are a superb place to start or a transverter from DB6NT or Down East Microwave in the states. Give 'em a google.

Here's a few pics of a 99.9% completed Mini-Kits transverter.

Look out for a Yeasu FT-2311R...Its a dinky 1980's vintage FM mobile radio giving a respectable 10 Watts on 23cms...Picked mine up for about 150 on ebay.
It can be easily programmed to TX and RX either end of the 23cms band (Just take the backup battery out of line until it self drains the memory then when you turn it on "L" will be displayed which stands for Low end of the band...simply dial your required lower end frequency and enter it. Then "U" will appear standing for upper end of the band...as before, dial your required upper end frequency and enter it. Then put the backup battery back in line and jobs a goodun!).
