@BoscoLab Nice setup! Wondering how effective the choked USB cable is at reducing / eliminating the radiated USB comms noise? I’ve taken to using WiFi for connection from IC705 for FT8 on iPad (with SDR-Control app). A full PC would provide more capability, but requires wired interface (via noisy USB link). TNX & 73

Released a working, simple C++ based Icom IC-705 UDP protocol communication example. Also contains optional PortAudio to play the audio stream on audio device.

I'm fed up with my ATU-10's screen turning off every 5 minutes. So I applied the software modifications suggested on the website. Now I just have to see if the internal battery drains any faster... #qrp #ATU10Tuner #ATU10 #IC705

The USB-C interface for my IC-705 arrived this morning from the US. I need to get started on replacing the old one right away. #qrp #qrpradio #QRPcw #IC705 #ic_705

Who needs a Flex (not that I wouldn’t want one): hunted #cw #POTA from a hotel room in NYC, using SDR-Control on my phone, #44Net Connect, and my #IC705 at home.

QRPing in the backyard in order to test that gears are OK. This time multi-length QRP EFHW with choke and trusty #IC705 on CW

OK just worked #K4NDX in SC from my backyard here in Brittany.
Rig is my trusty #ic705 with 5W.

The antenna is the "rotated delta loop for 10m" that is in Salty Walt's portable antenna sketchbook.

I've used my #IC705 as my main #hamRadio rig for some five years now. Time for a detailed report of my experiences.

Spoiler: Mostly good, but there are a few things I'm missing: USB-C jack, easy CW side tone audio level adjust, 5 GHz WiFi, USB-access to the SD card, open source firmware.

If the "detailed" of "detailed report" does not scare you (as in: fairly long), be welcome to https://dj3ei.famsik.de/blog/posts/2025/ic-705/ .

I unwrapped my IC-705, serial number 13001835, on November 21, 2020, so a bit more than five years ago. I’ve been using it as my main rig ever since and mostly like it. Time for a detailed report of

@jelle I really like my 705, using it is fun on a bun (as the kids don't say). #AmateurRadio #IC705 #Hashtag

My preparations for contact with the International Space Station. Reception is working very well. I can hear Oleg Platonov, a Russian cosmonaut. I still need an antenna for transmitting.
