Hello Nandu,

GREAT!! WOW!! I love it, this is the most simple antenna and transmitter , it is so simple and really fun

Congratulations for your QSO @ 100Km, I wish you more like this. It would be really great to have a QSO one of these day with your set-up.

Keep on the very good work Nandu.

I keep your site in my QRP favorites, as I can see there are a lot of interesting and simple things.

OH! If you have a way to measure it,  how many milliwatts do you have ? I'm curious,  ::)

Good dx'ing,

72, Michel VE2TH QRP & QRPp

Hi OM Mike,

That QSO was in the late 1970s when the noise level was quite low. The distance, as the crow flies, between Bangalore and Valsad is 985km. VU2SL OM Dalvir gave me a 449 report!

Those days, the conditions were so good I could work a 'W' on 7 MHz CW with a 6AG7 transmitter feeding the same dipole.

RF output of the SL100 was about 0.25W with a DC input of 1W and a big heatsink!

Thank you so very much for your keen interest.

Nandu.
