HUGE grin for today's Early Bird #hamradio #morsecode #cw #parksontheair #pota activation because #radioblackout produced 20m opening into VK land using @#youkits #hb1b with 4040-10m #EFHW antenna up 35feet. #amateurradio is AWESOME BABY

Well, after being licensed for 42 years I have my first ever QSO with China confirmed on LOTW from the CQWW CW contest. 100w from a Yaesu FT897 to an EFHW. Chuffed with that.

Today’s project has been an @mm0opx.bsky.social style efhw transformer for a club mate. Need to dig out the capacitors. Custom 3D printed box with strain relief for the antenna wire.

When you forget your 12v 3Ah #Bienooo battery, this is what 2.5 watts will give you during an Early Bird #POTA #parksontheair #MorseCode #CW #amateurRadio #HamRadio activation using the internal #FT817 battery into an #EFHW

Just worked my first station using my USDX+ V2 on 40m, a low EFHW into a 49:1 unun (bit of wire in the trees basically) and just the internal battery, so about 3-5w. Second call to M9IOC POTA station. #HAMR
