This programme looks at how amateur radio helped in the aftermath of the two earthquakes which hit El Salvador in October 1986. Around 1000 messages were sent on behalf of official organisation. 14313 kHz is the emergency frequency to monitor. Bob Horvitz reports on the political clandestine stations beaming into the area, including Radio Venceremos. FMLN has declared a truce.

The programme also looks at stereo mediumwave tests in China. On 10870 kHz Radio Iran Toilers is being heard from transmitters believed to be in Afghanistan. Receiver Development Update deals with Escom 500. Eddy Visser is working on modifications for ICOM receivers with a Phase-locked system. We also looked at what happened to Radio West, an updated AM filter on a Philips D-2935 and a new communications receiver, the SRX-351 from Germany.

We investigated why there is a pitch change to the Radio Netherlands interval signal and changes at RCI for SWL Digest.
