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/ .
Life isn't too short for QRP.
Today I went for 10W WWFF activation which turned into 5W activation as I forgot the battery lead home for my IC-705.
Of course I could have thrown a tantrum but I just laughed and thought "well this is going to be now different" (changes are good for humans)
I snatched over 30 QSOs on only CW with 5W, middle of day of scorching summer.
I would say not bad at all!
QRP is not dead! :D
Problems using my #IC705 radio together with my computer, the two connected via CAT via USB.
I use the rig's controls to change frequency. Often, frequency sync is lost: Changes of the frequency are apparently no longer communicated to the computer.
I use CAT-controlled Morsecode transmission heavily. That and other commands, including frequency changes from the compuyer, continue to work.
I've seen this problem with different setups, but all using hamlib.
Others seen this also?
I recently measured #IC705 transmit power 🧵. But I did not dive into output power's dependency on supply voltage. Jürgen DF3PM kindly made me aware of results by George, M1GEO. George found out that (unsurprisingly), output power drops as supply voltage is decreased from 13 V to 12 V or less.
Interestingly and somewhat surprising, output power is stable as supply voltage is increased to 14, 15, or 16 V, though efficiency drops.

Thanks, Jürgen and George!
