My first HF radio was a Yaesu FT-450D. This set was perfect to introduce me to the major amateur radio bands, major in the sense of “long distance”. I had acquired it by taking advantage of a promotion that offered the SCU-17 digimode interface. This duo is great, because it makes it quite easy to implement an environment that seems, at first sight, rather complex. I was able to discover and abuse PSK31, HellFeld, FT8, MFSK modes for a few years.
If you are a HF digimode user, you have everything you need to send emails through the Winlink gateways. The Amateur Radio Safety Foundation runs the Winlink service and offers radio amateurs a mailbox associated with their callsign in the form CALLSIGN@winlink.org You can create your mailbox by following the instructions on their website, right column. In short, you can create your account by logging in once without a password. You will then receive an email with your password.
In order to have an HF transmitter when I am on the road or when I am climbing a SOTA summit, I have ordered a QRPver 1_v.3.
This device works on a single HF band that you choose when ordering. I chose the 20m band version (14,000 to 14,350 MHz) which seems to me to be a good compromise between good propagation and ease of installation of an antenna. Moreover this band is rather well used in digimode.
Among the many digital modes, aka digimodes, there is one that I find really nice. If you saw the title of this post you will have understood which one I’m going to talk about.
MFSK, acronym of “multi-frequency shift keyed”, is a family of digital modes that dates back to the 1960’s but is still interesting because it transmits data with an error correction code (FEC) and it also allows sending images!
A first post to see that all works !
