The VOA Radiogram frequencies have been large free of co-channel or adjacent-channel interference. [Except on 5745 on the West Coast -Hugh] To determine how well our MFSK modes can cope with interference, we will insert some interference of our own during this weekend. The “interference” will be in the form of the song “I Remember You,” sung by Slim Whitman. Mr. Whitman’s vocal range, spanning octaves, may create a challenge for MFSK.
Also this weekend will be a VOA News story in MFSK32 and in the Flmsg format. We have not transmitted an Flmsg-formatted story recently. This weekend, if it is received successfully, the VOA News story will pop up in a new window of your web browser.
Here is the lineup for VOA Radiogram, 8-9 June 2013:

Utilities are all VLF/LF/MF/HF (and sometimes low-band VHF) radio communications except broadcasting, CB, and non-emergency amateur.
