VOA Radiogram — More Digital PSK Mode Trials

Again I received fairly late notice that this weekend Voice of America is trial broadcasting several PSK mode broadcasts.

VoA Radiogram

VOA Radiogram — “Soft launch” of VOA Radiogram this weekend.

  • Modes menu for VOA Radiogram, March 23/24, 2013

    VOA Radiogram for March 23/24 will be similar to the past weekend’s program in that it features the PSK modes. Much of Kim’s script will be the same. In this weekend’s broadcast, however, only one mode at a time will be transmitted. This should improve the signal-to-noise ratio and ability to decode each mode.

    Each will be centered on 1500 Hz:

    1. BPSK31 (1:00)
    2. PSK63F (1:00)
    3. BPSK63 (1:00)
    4. PSKR125 (1:00)
    5. PSKR250 (1:00)
    6. PSKR500 (1:00)
    7. PSKR1000 (1:00)
    8. PSKR125 (3:45) Plain text
    9. PSKR250 (2:40) Flmsg* formatted (with html)
    10. MFSK32 (0:55) Image

    *Install Flmsg. Then, in Fldigi: Configure > Misc >  NBEMS > under Reception of flmsg files click Open with flmsg and Open in browser, and below that state where your Flmsg file is located.

    If decoding performance is still not satisfactory, VOA Radiogram in future weekends will feature more robust modes, such as MFSK, MT63, and Olivia.

    See VOA Radiogram: how to decode the modes.

This is a neat extension of both the use of the PSK digital modes more popular in Amateur Radio and VoA broadcast mission.

Voice of America operator plans “sunset” for shortwave radio broadcasts – Boing Boing

Guess one knew it would come to this, but it is sad days nonetheless:

The sun is setting on Voice of Americas shortwave radio service, heard worldwide in dozens of languages for 70 years.A strategic technology plan prepared by the Broadcasting Board of Governors BBG, the federal agency responsible for Voice of America, Alhurra, Radio Free Asia and other international stations, concludes that it should end many shortwave broadcasts in favor of “more effective” media such as internet radio.

via Voice of America operator plans “sunset” for shortwave radio broadcasts – Boing Boing.

Years ago I would often spend time with people training for broadcasts like this, and do miss those days.
