This one is AWESOME:
In days of old when ops were bold
and sidebands not invented,
the word would pass by pounding brass
and all were well contended.

Not to hijack the thread, but anyone have a general idea how much improvement
one would get by going from 8 to 12 gull wing resonant elevated radials on a
60 foot base loaded vertical?

N7LF's work also shows that more elevated radials are better than
fewer. Since the losses

So what is this DX window? 1825 to 1830 kc? If that's where the DX calls
and transmits then where do W/VE stations transmit in reply?
The idea is that W/VE stations do not call CQ in the window, but can respond to
a DX

Wonder if someone can help with a technical question with the amp I use on 160
meters.
The Spec Sheet for the 8877 tube lists the Absolute Maximum Plate Voltage of
4000 Volts for the tube, and also says in typical operation the plate
voltage is between 2700 and 3500 volts. In my amp (Ameritron
I amazed at the number of DXers who call non stop, almost regardless if
whether PT0S is working someone. And then, my favorite, 7DX??. And many who
have no possible relation to that call keep sending.

Good Day,
I am considering an FTdx-5000 (currently use an FTdx-9000) for 160 meters and
wondered about the Image and IF Rejection figures of the 5000. They are 60 and
99 db respectively. The Image rejection is about 50 db less than the 9000. I

Hi Joe,
I don't have any advice. Only some words of encouragement regarding compromise
installations, and that they can yield a substantial improvement.
I live on a small city lot, no more than a quarter acre. I have tried a dozen
receive antennas (K9AY, EWEs, coaxial loops, low dipoles,
I think the idea is that a qrp station might not be heard by a station so weak
the qrp station needs a beverage to hear him.
Of course, one could describe circumstances where that would be true and others
where it would not be true.
I thought it was clever

It has been asked: Why don't more people use LOTW?
I put it off using LOTW for years because I feared, incorrectly, that it would
be difficult to set up and use. Just last week, I finally got up the nerve to
try it. Much to my pleasant surprise, LOTW was very easy to set up. So,

I currently use the spray on my patio, lawn and driveway as a ground system. It
works so well I took down my elevated radial system which made my XYL very
happy. Now I have a much more efficient antenna AND a much happier wife. I
have worked more DX on 160 this season than in all prior years
John,
Do not despair, my fellow Topband Aficionado!
I also live on a 1/4 lot in a residential subdivision in San Jose - part of the
Black Hole of the 160 meter world. I don't have the luxury of living on or near
the East Coast where working Europe (with lots of DXCC entities) is the same

Good Morning:
I have a very modest 160m station. Since I cannot hear as well as most of you,
I run the risk of calling CQ on what appears to be a clear frequency and QRMing
a DX station calling CQ or disrupting an ongoing QSO.
Any suggestions on how to prevent?

Mike,
If your rig does not have an RX only port, you can use a rx/tx relay.
There are a number of commercial units available. One (with which I
have no connection whatsoever) is made by KD9SV and is available through
Radioware.
It has an rx protection circuit (to keep you from blowing out

Dear Topband Aficionados -
I could use a little help. I am currently using a 60 foot base loaded
vertical, with an 8 diameter coil made of copper tubing. I know top
loading gives much better efficiency. The problem is, my lot won't allow
the two top loading wires to be in the same plane, so
