Radio Console

Lowest level, left to right: Computer, Screen, Morse keys and keyer*, Icom IC7400, SB-101* with top band added, SB-600 speaker, stabilised power supply* for the SB-101, IMRC R700M synthesised HF receiver. I was involved in the R700M development in the early 1970s.

Level 2, left to right: Completely re-engineered SB-310* that now covers all HF and WARC bands and to its right is a matching SB-401* which has only been modified to include 160m and full elelctronic break-in. 1.8 - 146MHz dual Z-Match*, multi-rail high voltage power supply*, power supply* for 1.4V valve equipment.

Level 3, left to right: HW32 and power supply*, rig switch console*, aerial switch box*, SB-620 Panadaptor, SB610 station monitor,  13.5V 25A power supply*, own manufacture crystal calibrator and absorption wavementer in the mid 1970s, BNOS 13.5V 25A power supply, AKD-7003 70cm channelised FM rig and Multiquartz-16 2m channelised FM rig.

Highest level: Daiwa aerial rotator and broadcast receiver. The rest is work in progress.

Test Bench

Bottom row left to right are an HP8640B signal generator, Rigol 1.5GHz spectrum analyser, Marconi TF2008 signal generator, Marconu TF897 audio power meter and behind the lamp and box of small tools on the right is a TF2212A XY display that may be used with the TF2008 signal generator and a log amplifier/detector.

Middle row: the blue unit is a work in progress collection of small items of test equipment contained in a single enclosure and to its right is an R&S 2.5GHz wavemeter, two low voltage power supplies, an HP1741A 100MHz dual beam storage scope and a Rigol 100MHz dual beam digital scope.

Top row, left to right: Type 193A crystal test set, much modified CT82 noise generator with an external noise generator head, Bird Type 43 throughline power meter, Bird 100W 50ohm dummy load and a TF1246 LF-HF power oscillator for use with a TF1245A Q Meter.
