I have 2120 #ft8 which is cool and all but. VarAC is so freaking cool, I've made like 10 contacts but they were real conversations that sometimes went on for an hour.

I did a little bit of FT8 earlier and it was such a perfect illustration of band ranges.

With the sudden appearance of #FT2, I'd like to take the opportunity to announce the new mode FT∞, which is designed to use a bandwidth of 31 yoctoHertz, at a power level of 1 femtowatt.

Unfortunately, the effective throughput is so low that the only message ever sent using this mode started in the Mesozoic Era and has yet to finish. (Rumor has it that it includes the word "destinated", and that one of the parties didn't give their grid square.)

@DJ5CW I, for one, am eagerly awaiting FT⅛, which will require a minimum of 1kW output power as well as a local GPS-disciplined Cesium time standard. (But imagine the throughput! Contesters will be able to win using this one weird trick!)

FT2 - der neueste "Hot Shit"

FT8 und FT4 sind beide moderne digitale Betriebsarten (Digimodes) im Amateurfunk, die von Joe Taylor (K1JT) und Steve Franke (K9AN) im Rahmen der WSJT-X-Software entwickelt wurden. FT8 wurde am 29. Juni 2017 veröffentlicht. FT4 wurde im April 2019 (Beta-Version) eingeführt. Doch jetzt ist FT2 im Rennen, vermutlich der schnellste Digimode, der je entwickelt wurde. Ein erster Kontakt in diesem Digimode fand am 16. Februar 2026 auf 80 bzw. 40 Meter zwischen IZ8VYF, IZ8XXE, IC8TEM und I1JQJ statt.

FT8 hat sich in den letzten Jahren als Quasi-Standard für allgemeine DX-Verbindungen etabliert, während FT4 hauptsächlich auf spezifischen Frequenzen für Conteste genutzt wird, da es rund doppelt so schnell ist wie FT8. Doch mit FT2 könnten die Karten neu gemischt werden: FT2 sendet in deutlich verkürzten Zyklen, gerade mal 3,8 Sekunden werden benötigt. Ein QSO wäre damit in 11 Sekunden abgeschlossen, d. h. FT2 ist 4x schneller als FT8 und doppelt schnell wie FT4!

Bei 3,8 Sekunden mit einer Bandbreite von 150 Hz (grüne Kurve) beträgt die Empfindlichkeit -12,5 dB (SNR). Der Verlust im Vergleich zu FT8 (-21 dB) beträgt etwa 8 dB, wird jedoch durch eine vierfache Geschwindigkeitssteigerung ausgeglichen. Für Szenarien mit starken Signalen wie DXpeditionen, Wettbewerbe und Pile-ups ist dieser Kompromiss jedoch von Vorteil.

Als Modulation wird 8-GFSK verwendet, die Bandbreite liegt bei 170 Hz, die Payload beträgt 77 bit. Bisher genutzte Frequenzen: 3582/7077 kHz.

#HamRadio guy. My #HF system band-hops 160 thru 6meters (10 bands) monitoring #FT8 traffic. On 1 of the bands, the radio needs to change antenna setting. Vibe-coded a python app that queries #flrig for the current frequency & sends command as needed to switch it (pictured).

youtu.be/0HlnDVjEd1I Does your computer clock have to be super well synchronized to UTC for #FT8 to work? NO! And I prove it. #HamRadio #AmateurRadio

Too Much Power On FT8?

As you know, #TheOldsToday will tell you to stop whining because Back In Their Day they'd wait years for a confirmation & also they were limited to 75 W input & were *rock-bound* on the Novice bands & blah blah blah.

Annoys me, too. #FT8 is, of course, the way & the light. Majority of ops upload to LOTW right away & boom, in 2 years of casual operation at a new QTH you have 112 confirmed. The rest seem to be #olds who don't see why anyone is in a hurry so they wait 4evah to upload.

The last three days of "radio hunting" on the 20-meter band (good old FT8) felt like a world tour without leaving my chair. My DXCC collection is growing faster than my coffee consumption!

Huge thanks to the operators who didn't ignore my digital "pings":

Isle of Man (GD7DUZ) — Country (86), Albania (ZA5G) — Country (87),
Cameroon (TJ1GD) — Country (88),
Nauru (C21TS) — Country (89),
Estonia (ES2DR) — Country (90).

Huge thanks for the successful QSOs.

Just worked XU7O in Cambodia 🇰🇭 (Gridsquare: OK21 / distance: 9250.2 km) on #80m using #FT8 #hamr #wavelog #dx #hamradio

Just so you know, we're still doing this thing on #6m #FT8, including double hops into AZ and CA.

Just picked up an FT8 from Kyiv, Ukraine! His contact page is...just...WOW.

Good luck over there, UT5UF. I wish your neighbors weren't so shitty.

Whoa Nelly! Just worked six New Zealand stations on #6m #FT8!

Speaking of being in the right place at the right time...WOW!

#hamradio #amateurradio

I don’t always do ft8, but when I do I’m usually testing an antenna. I didn’t send much because I’m inside and it’s a lot, but it looks pretty good for a wire on a wall in the middle of the night.

Just caught 4U1UN on 40m band FT8, and I'm kinda geeking out. This is sooooo addictive!

Funkverkehr in Europa in FT-8 auf 80 Metern gerade.

Ich darf nur zuschauen, aber am Dienstag ist Prüfung. Drückt mir die Daumen.
