Re: Topband: Small garden DX

Petr, I put the diodes before a common mode choke which I think is the right 
place for them to be as the choke will isolate the front end of the preamp  
from the diodes. If we were talking about uWaves, then it would be a big issue 
and one would use a relay to provide the isolation on TX and protect the 
preamp, but does it really make a difference on 160m  and the nF ?

Roger,

That is late evening/early morning in the North America. I'm fast asleep on 
weekdays since I have to get up for work.

I try to operate during your sunrise on Friday and Saturday nights when I 
remind myself to take a nap during the day. Not as young as I used to be...

A lot of us are either regaining sleep after CQ WW Phone, AND/OR we spent
most of the night listening to the 3C1L pileups :-)

Topband: No American activity

[Roger Kennedy]

There are usually several of us Europeans on at around our Sunrise (about
0630Z) . . . 

But even though the band is open (as you can see on RBN), no stations about
to work !

Hi John,
congrats...

Just 1p note > be careful with the back to back diodes in the front-end.
These are not the best solution in some cases because of possible IMD
issue.

Topband: Small garden DX

[John Randall via Topband]

Lat night I worked two stations YU1XA and I5JVA and was happy with that, then 
went to bed. I have now cured most of my QRN and common mode problems and could 
see weaker stations on the flex panadapter. Silly me, I did learn a painful 
lesson £2.50 when my preamp went dead and upon opening it up, I realized that I 
had forgotten to add double back to back diodes across the preamp input. A new 
2n5109 and protection diodes was soldered into place and I was back on the air.
Next step is to make a loop antenna for receive.
