Radioddity GD-73A

The GD-73A (TYT MD-430) is a low powered dual timeslot UHF DMR/FM radio that’s recently been released for the amateur radio use.

I believe that the original purpose of this radio was to fill the Family Radio System or the European 446MHz short range with limited power and a fixed antenna.

However Radioddity are targeting the hotspot roll where you are generally only a few meters away from the hotspot. So it has two power levels, 500mw (low) and 2w (high)

My first impression is that the radio is comfortable in the hand, but has a very light PTT button. So it’s pretty easy to key the radio when you don’t mean to! The battery life is approximately 2 days just receiving and around 8 hours on transmit on high power (2w)

The small form factor is a comfortable size, but that PTT needs to be fixed. The provided programing software is fairly typical for a Chinese built radio, it’s not the best, but it does the job. It lacks any ability to import/export to CSV files like most other radio’s support.
