Glad to see that HADES-ICM repeater is now continuously on. Only problem for me is the 40mW output, which may not be enough for my limited antenna setup to pickup! Good luck to all with better setups.

Beautiful scenery around for enjoying a SOTA with hand held radio! Wonder which radio, antenna and band it was? 73

When I looked at the voice repeater schedule of IO-86 satellite for this weekend, I noted that there are several special voice repeater schedules for Rattlegram, being the tenth anniversary of the satellite. youtu.be/YN_fYE5C7YE
Any one listening to amateur radio nets would have heard many operators mentioning the humidity percentage in their radio room. Have you ever wondered how these type of electronic instruments measure humidity? youtu.be/pxc5S2gCEPs
160m vertical antenna, that too with elevated radials! Really mind boggling. That is the only conventional amateur radio band I have not been able to touch. Though I can tune in with a tuner and 80m dipole, noise level here is up to 9+30 dB.

I was tuning around with my revised full wave loop antenna for 40m to check performance on other bands. So far I had not seen SSB signals on the waterfall display of my radio with previous antennas on 12m band. youtu.be/dnmMxWSkgos
I had homebrewed a ladder line along with a full wave loop antenna for 40m using 60m long 2.5 sq mm insulated copper wire. 'Steps' of the ladder line were made using 2 inch long 6mm diameter black drip irrigation pipes which are UV protected. youtu.be/My6XN1_ZDQU

What happened to AO-123? It was one of the new FM satellites on which I could have a comfortable DX QSO with E21EJC. Earlier it had changed from weekly activation to continuous activation. Now the FM repeater is not seen to be active.
I had posted my view on why my ladder-line with full wave loop antenna meant for 40m was not tuning well on 40m, while it had good results on higher bands. youtu.be/zBBNi9iDl_s
