HF Transceiver
The main station radio: 160 through 10 metres, all-mode, 100 W class.
A pocket radio for local contacts, repeaters and public-service work.
| Bands | 144-148 MHz (2 m) and 430-450 MHz (70 cm), region dependent |
|---|---|
| Modes | FM narrow, plus digital voice modes on many models |
| Power | 5 W typical, with 0.5-2 W low settings for battery economy |
| Sensitivity | Around 0.2 uV for 12 dB SINAD |
| Battery | Li-ion pack, 6-12 hours at low power with 5:5:90 duty |
| Antenna | SMA or BNC, supplied whip is a compromise design |
| Interfaces | Some models offer APRS and GPS |
A handheld covers the 2 metre and 70 centimetre bands, where contacts are normally local and made through a repeater or directly between two stations in sight of each other. It is the radio most new operators buy first because it is inexpensive, self-contained and needs no antenna installation.
The limitation is physics rather than the radio. At these frequencies signals travel almost entirely by line of sight, so range depends far more on antenna height and the terrain between the two stations than on transmit power. A handheld on a rooftop antenna will routinely outperform the same handheld inside a building.
Handhelds are usually low power, but never transmit with the antenna close to your face or body. Hold the radio so the antenna is at least a few centimetres from your head, and never key a handheld with no antenna fitted.
