Yaesu FT-270R - 144 MHz Transceiver

Used for communicating with local radio amateurs since range at VHF is more or less restricted to line of sight, although in certain favourable conditions the range can increase dramatically.

This equipment is now about 15 years old (very dated) and was intended primarily for mobile use. Capable of about 30 watts output despite its small size it was probably quite state of the art in its day and received excellent reviews when first introduced. I'm looking for a legitimate excuse to get something more modern but it refuses to expire.

RIG RX2 137 MHz Satellite receiver

The RX2 was designed by a team led by Ray Godden as a low cost 137 MHz receiver for the reception of weather satellite images. Continuously scans up to 5 channels. It is only available as a kit to members of the Remote Imaging Group. This project has been hugely successful with over 1500 kits sold to date. Costing only 55 its performance is on a par with the most expensive commercial receivers. Case, connectors, S-meter and power supply are not supplied in the kit. A completed PCB is shown in the upper photograph.

The lower photograph shows one that I built about six years ago.

Dartcom Satellite Receiver.

This is the receiver which I use regularly for satellite image reception. Sensitivity is sufficient to get excellent images without the use of a pre-amplifier. It is marginally superior to the RX2 and I purchased it before the RX2 was introduced otherwise the expense would not have been justified. Switch it on and forget about it.
