“How to Radiogram” tutorial series on new GueroGram youtube channel

Today we announce the beginning of a new YouTube channel run by HFZone member Guero. This channel starts with a tutorial series titled “How to Radiogram” which covers some of the basics of encoding text and images with the fldigi Digital Modem program in the style of the venerable VOA Radiograms.

How to Radiogram Part 1: Encoding text

How to Radiogram Part 2: Encoding images

Other tutorial series and common interest videos will follow covering topics such as Short Wave Listening (SWL), antenna experiments, and other radio hobby esoterica. Please gently press “like and subscribe” when you visit the channel!

Comments and feedback can be sent to GueroGram@gmail.com

HFZone Radiogram series contributions for Monday 9 May: GueroGram Episode 1b

Several of us HFZone community members are aficionados of the Radiogram concept and big fans of Kim Andrew Elliot’s Shortwave Radiogram program that airs on WINB and WRMI.

As a tribute to SWRadiogram and celebrating this exciting aspect of our hobby some of us (including blog contributor J3ff and myself) have begun to compose experimental attempts at radiograms encoded in various digital modes including MFSK32 and MFSK64.

We are not ready to send these experimental recordings for SW transmission just yet, but we do want to make them available here for other community members to attempt a decode. Any feedback you can provide us will help us develop our craft in constructing good radiograms!

Here is my first contribution: GueroGram Episode 1b

New Azimuth Map for WRMI A22

As you may be aware, WRMI has made some transmitter adjustments for the A22 season (something about 17th harmonics…) Here is an updated Azimuth map. Changes include 7730 being a new 44° azimuth for EU, and 7780 now transmitting 222° to Central America.

Do you want Azimuth maps for other transmitter sites? Ask Guero in the HFZone Discord!

Guero’s A22 WRMI Program Grid

Greetings all! As part of my ongoing dedication to better SWListening, I am providing my improved version of the WRMI Program Grid. You can download a copy of the xls file at this link: Guero’s A22 WRMI Grid

A few notes are worthy of mention–

Focus: This grid puts emphasis on the WRMI programming that many of us in HFZone find interesting or noteworthy, and downplays other programming. Programming types are color-coded except for religious programming.

Errors: WRMI often adjusts its programming for technical or other undisclosed reasons. This grid should be treated as a live document. Please let Guero know of any updates via the HFZone Discord channel.

Aim: This grid serves as the basis for much of the HFZone Calendar and I try to keep the two synchronized.

Enjoy! –Guero

WRMI azimuth maps

Have you ever wondered which direction your favorite program is being beamed? Do you know which frequency has you in the beam? Look no further. Here are some handy maps to demystify the WRMI broadcast station azimuths! Updated versions of these maps will be posted at HFZone.org!
