Today in the Middle Atlantic, the weather is delightful (but we could use some rain). Shortwave propagation has been less than delightful, with static crashes from offshore storms adding to the mix. I hope conditions improve in time for this weekend’s broadcasts of Shortwave Radiogram, although our MFSK32 text enjoys a challenge.

Our last transmission, Tuesday at 1430-1500 UTC on 9955 kHz from WRMI Florida, can be difficult to hear during the summer. Cuban jamming is also present on the frequency, probably as a result of certain programs now or previously transmitted by WRMI. That jamming seems half-hearted, so it rarely impedes the decoding of our modes. WRMI on 9955 is beamed at 160 degrees, but the antenna seems to propagate well off its back, which would be 340º. So for this troublesome transmission, reception might be good in Georgia, Tennessee, the upper Midwest of the USA, and maybe even into the Canadian prairies.

A video of last weekend’s Shortwave Radiogram (program 308) is provided by Scott in Ontario. The audio archive is maintained by Mark in the UK. Analysis is provided by Roger in Germany.

Here is the lineup for Shortwave Radiogram, program 309, 15-20 June 2023, in MFSK modes as noted:

  1:45 MFSK32: Program preview
  2:50 MFSK32: Nickel-based batteries can replace cobalt
  6:28 MFSK64: Railways could be conveyance for backup power
