As many as 40 (!) different SP-600 versions have been manufactured. It started with the SP-600 JX-1 in 1951. Most versions have a frequency range as stated above, but there were some exceptions. For instance the SP-600 VLF only covers 10-540 kHz and the SP-600-JLX-2 (1951) covers 100-400 kHz and 1.35-29.7 MHz. The last SP-600 was the SP-600 JX-21A which was in production until 1972. This was also the only SP-600 with a SSB product detector.

From the outside, most versions look quite similar, but circuit modifications where made throughout its lifetime. Many models were custom ordered for military or naval duties. It is not believed that the SP-600 was used on board ships, only on shore stations.

For reference, here is a list of all the versions I could find: SP-600-JX-1, SP-600-JLX-2, SP-600-J-3, SP-600-J-4, SP-600-JX-6, SP-600-JX-7, SP-600-JX-8, SP-600-JL-9, SP-600-JX-10, SP-600-J-11, SP-600-JX-12, SP-600-J-13, SP-600-JX-14, SP-600-JLX-15, SP-600-JL-16, SP-600-JX-17, SP-600 JX-18, SP-600-J-19, SP-600-J-20, SP-600-JX-21, SP-600-J-22, SP-600-JLX-23, SP-60O-JL-24, SP-600-J-25, SP-600-JX-26, SP-600-JLX-27, SP-600-JX-28, SP-600-JX-29, SP-600-JX-30, SP-600-VLF-31, SP-600-JX-32, SP-600-JLX-33, SP-600-JL-34, SP-600-JX-35, SP-600-JX-36, SP-600-JL-24, SP-600-JX-37, SP-600-VLF-38, SP-600-JX-39 and SP-600-JX-21A.
