7.1 MHz -.29 dB at -9.0 degrees phase shift
Remember single transformers are 1/2 these values.
Single antenna losses only are quite acceptable at 630 meters and 4 turns
primary on a BN73-202 as loss wise one transformer is down less than 1 dB at
100 KHz.

already expensive electronics. For this reason I have to do as well as I can to
predict the future for my products. My observation is that leaded parts are
disappearing rapidly and this will continue.

unfortunately is pricing itself out of the market now. I suspect the
2N5109 will follow as inventories shrink.. A pair of the 18A devices at ~$1.00
USD each single price in a push pull Norton configuration would in my opinion
make it worth trying as a killer wideband amp.
Just my $.02 USD.

Huge day for me this morning
After several years of trying, I worked my first VK on Top Band! Well
some
contesting from there. Also Jimmy's logs are still on site as well. A brief
look showed it worked pretty well. Morocco is about 32 degrees North. YMMV

I thought I saw one spot on 1823 for them..you were
in that area. I was doing maintenance and listening only, so I didn't note your
frequency but heard your call loud and clear..-)

I suspect it's because someone thought you were QRMing TJ2TT; He was pretty
much QSA0 for me. Local QRN/QRM has made 160 very tough for me; I could barely
hear Roger and he is usually fairly easy copy.

I have no explanation for this but it is clearly the best signal every heard
from this part of the world on 160 from 3C0W was so strong i had to record
it. Jon, AA1K has put it up on his website http://www.aa1k.us/dx for you
