How much return loss is acceptable certainly does “depend”.
I’ll throw in another consideration to further complicate matters:
The higher the VSWR, or lower the return loss, the more power is lost in the

How much power is lost depends on the type of cabl

Nothing beats a bit of context and perspective
Plus, I love the increased DX activity a contest brings.

Dear Fellow Topband Enthusiasts:
I'm hoping to get a little help here:
Q: Will I see noticeable improvement if I change my radial system to a FCP
and/or raise the base of my elevated vertical?
Background: I have a 60 foot tall vertical I use on 80 meters, which I also

Hi Roger,
You might have been referring to my comment, which was not intended to say the
7800 has a "poor" receiver.
However, I had a 7800 for 6 or 7 years (and loved it). I then purchased a 990,
which I had side by side with the 7800 for several months. I can tell you from
personal exper
Hello Barry,
I have been using the 990 for over a year and use it daily on the Low Bands. I
find it an exceptional performer. The ergonomics are not quite as good as the
ICOM 7800, but the receiver performance is much better. The capability of the
radio is at its best on the low bands, if you
I have both systems.
The DXE 2 element system is 80 and 100 feet from my transmitter antenna,
respectively. I have run 1.5 kW for the last several years without any
problems, and with no sequencer.
The Hi-Z triangular system is even closer (65') and has never had a problem.
YMMV,

People should be free to operate any way they please - within the rules. I
understand this discussion is about what the rules "should" be.
It's all about having fun! It's also about striking a reasonable balance
between the many benefits of remote operation (discussed here multiple times)

I worked the HS0 for a new one (139) this morning BUT my log just crashed and I
forgot his suffix. Did anyone else work him and know the full call?
Please help.

Thanks to everyone who provided very helpful advice. I've tried to respond to
everyone individually, but in case I missed anyone - thank you!
I'm on the fence about changing the radial system. I'll probably lay down the
radials when we do the landscaping "just in case" and before "it's too
Thanks Eddy,
Rudy's work is excellent and I've studied much of it in detail!
My question, in-artfully posed, related to the impact of the house on a ground
radial system, not elevated vs . Ground radials.
All the best!

Hello Fellow Topbanders -
We are about to embark on a front yard landscaping project at our home on a
tiny 12, 500 sq. ft. lot.
It occurred to me this would be an excellent opportunity to put down a large
number of buried ground radials BUT, they would only cover about 90 degrees of
the compa

Good Morning,
I am finally getting around to detuning my 160/80 meter vertical on receive and
plan to use a simple 12v relay to turn off the power to the antenna switch and
the DXE Time Variable Sequencer to make sure the on/off timing is correct.
Before I go down that road, does anyone have
