VHF / UHF (Over 30MHz) Transceivers

Yaesu VX-6r VHF/UHF handheld

When outside I often use a small Yaesu VX-6R handheld radio.
The wide frequency range and scanning features make this small radio perfect for listening around not only the amateur bands, but also the normal broadcast, air, marine, PMR and shortwave bands.

This radio is also ideal for taking out in the car when used with a small discrete mag-mount antenna. I simply place the handheld into a mobile phone holder which prevent it sliding around.

Here’s a short recording of astronaut Tim Peake talking to school children on Saturday March 05 2016 at approx 11.00am GMT received on the International Space Station (ISS) downlink frequency of 145.800Mhz using the VX6r and a mobile antenna. Due to the distant location of the school talking to the space station it was not possible to hear their transmissions.

Vertex Standard VX-351 PMR handhelds

I also have a pair of Vertex Standard (Yaesu’s parent company) PMR handheld radios.

These radios are capable of covering the 400 – 470 MHz UHF frequency range across 16 pre-programmed channels. Various methods of access control can be used, such as CTCSS or DCS encoding.

In the UK, these are normally supplied programmed to the 8 licence-free PMR channels. Software to program the channels is available and makes the re-programming of these easy.

Both my VX-351’s are programmed identically, the first 8 channels to the UK PMR frequencies. The remaining 8 channels are programmed for the 70cm calling channel and some local 70cm repeaters.
