[#]CW100days

Spent a large part of the day playing with my FTdx10 and my (new to me) 2004 TenTec Orion.

Listened to #CW contets on 40m and 20m.

I was testing how the Orion deals with heavy QRM and QRN, and exploring it's rather special AGC and NR setting.

In the mean time I tried to copy callsigns.

Contesters repeat their callsign ad-lib, and this helps.

Got some, in full or part, between 23 and 28WPM.

I used https://rbn.telegraphy.de/ to check the speed.

P.S. Listening to QRM and noise thru a 100Hz bandwidth filter for hours, I got a serious headache !

@F4JWJ @dj5cw lowering the RF gain or engaging attenuation definitely improves listening fatigue.

@F4JWJ @dj5cw@mastodon.radio FWIW, I rarely use such narrow filters. My default is 500 Hz or even 700 Hz. I also don't enjoy the sound of very narrow filters!

@DJ5CW@social.darc.de @F4JWJ @dj5cw@mastodon.radio Today, I was happy to replace 500 Hz by 250 Hz. Its challenging enough to copy a single station. But with two or three other contesters in background...

I even use 50Hz BW + strong NR on the FTdx10.

I live with S7-S9+ of very harsh sounding QRM.

That's why...

And my headache is still here. Maybe I simply caught a cold !
