Today I did an activation with a new antenna.
it is a 40-20 efhw with a loading coil.?

I built it and tuned it up at home. It had an SWR on 40 of 1.4:1 and 1.0:1 on 20 meters.
When I hung it in the woods today, I was surprised that the SWR was 4.4:1 on 40m. On 20m it was 1.0:1.
I had never had this happen before but even with the high SWR on 40m I was able to get about 3 watts cw out with the power set at 60%.
So I was able to make plenty of 40m contacts. I was surprised that the TX-500 still put out 3 watts and no harm was done.
I am continually amazed by this radio.?
‘I don’t plan on repeating this as I am sure it is not a good practice but in a pinch it pulled through.
‘Now to figure out what the issue is with my antenna.

fb, om! (have tried to get you a couple times while /p for a POTA contact using your designed key)... i have found the same benefit of the tx-500: robust finals... last rig i had that could easily handle 3:1 or greater was my sgc sg-2020, which had 20W out on 40w finals (rig could also double as a wheel chock if you got a flat tire)

i can run my tx-500 on my poor ham's tactical delta loop on 20 and 40 with no tuner!

:-)

I’ll listen for you next time I am out, ?
it is always nice to work n0sa key to n0sa key hi hi
