Type: TRF receiver;
Frequency control: fixed tuned to 500 KHz.
Power: Powered by 24 VDC from ships batteries.
Comment: Not capable of CW reception only MCW. Because it had no BFO, it would shut down upon the receipt of a CW transmission. Most were of the Mk 1 variety and only tuned 500 KHz. The final version was modified to be tuneable and cover much of the HF band as well.
Also known under designator NS101.
