The radio on the left is indeed a Wireless Set No. 88. Well known to many CCF cadets of the 1960s, it replaced the old wartime WS 38 Mk 2/3 which used 7.3-9 MHz AM.
With 4 crystal controlled VHF-FM channels, the WS 88 Type A used 40.2-42.15 MHz and the Type B used 38.01-39.7 MHz. A less-than-massive 250mW transmitter power gave the thing a range of only about 2 miles. No volume control or squelch, so the operator who wore that clumsy headset had white noise blasting out his ears the whole time. The second pouch contained a huge, heavy HT/LT battery, 90 V HT and 1½ V LT. Tx/Rx was controlled by that suspicious looking object, the 'pressel switch', next to the 'officer's handset'... But it was much, much more user friendly than the old 38 set with its frequent need for calibration and retuning.
When the Type A was issued to schools near London, it was found that Channel B on 41.4 MHz interfered with BBC Channel 1 sound from the Crystal Palace TV transmitter on 41.5 MHz. To stop any mischief, the Type A was modified with a large rivet to block the frequency selector from Channel A or B. But in conditions of good 'lift', it wasn't unknown for continental TV to break through even on Channels C and D!
The radio on the right is a 'Station Radio A40', which replaced the '88 set'. It had 6 channels in the 47-54 MHz range but still used valve technology; however, it did at least have slightly better range than the 88 set.
