Testing a PRC2000 on 40m USB

Last Friday a colleague from Belgium and I tested some manpack radios, among which was the PRC-2000. The PRC-2000 (also known as Callpack RT-2000) was built in Great Britain by M.E.L./Philips. It is a fully transistorized radio for portable and vehicle use from the late 80s.
The PRC-2000 is a versatile microprocessor controlled HF transceiver for use in tactical field operations. Within the 1.6 Mhz to 30 Mhz HF frequency band , the transceiver can operate on any of 284.000 cannels spaced at 100Hz intervals, to provide single side band LSB/USB voice or data communication, or continuous wave CW Morse communication. In addition to manual channel selection, frequency and mode data for up to 10 channels can be preset in non-volatile memory for immediate recall as necessary.
Here you can hear it in action on the 40m amateur band:

The PRC-2000 operating modes are USB / LSB / CW / DATA. Antenna tuning is fully automatic. The output is 20 watts on high power and 4 watts on low power. As options, there are solar and hand generators, as well as an amplifier.
