Ultra-Picokeyer

#morse
Since I can’t make any more progress in learning Morse code with the Koch method, I’m trying to learn in a different way by doing something that is not recommended: generating Morse code when I can only decode it with difficulty. I don’t know where this will lead me and I don’t recommend this to anyone at the moment. I am experimenting! For that, in order not to clutter the radiowaves, I took the option to acquire an autonomous keyer on which to plug my key.

a SOTA bag, lightweight version

#SOTA
I’ve already introduced you to my backpack for field operations and SOTA, but I have a second lighter one if the trip is a bit long or if I’m not sure to use the radio. This one weighs only 800 grams (instead of 6.5kg)! It consists of the following items: a D104-M6B amplified Astatic microphone a QRPver-1 v.3 (4w) transceiver in 20m version (single band) a rechargeable battery pack EFHW antenna for 20m a coax a throw-bag and a rope I also have a small Morse iambic key.

My SOTA and field operation backpack

#SOTA
When I operate in the field or on a summit, I like to have all the stuff I need. To do, I have a complete backpack to operate on HF and 2m bands in SSB, FM, digimode and even CW. For this last mode, I require technical help… I will be more clear later on. ;-) So, what is the content of my backpack ? It weighs about 6.5 kg.

Hugo blog with Mastodon comments

#software

Inspired by Carl’s article, I’ve adapted its solution to embed Mastodon/Fediverse discussion into a static web site as a comments system.

Here, I share what I have done in my Hugo theme.

The SDR display

#hardware
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.

Waiting for QRPver 1_v.3

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.

Images with MFSK-16 mode

#fldigi #digimode #mfsk
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!
