Ugh - Let me go on the record as saying I don’t like this idea and I wish this
can of worms was not opened! Thankfully US stations (and hopefully others) no
longer have second (personal) calls. Yes we have club calls, but thankfully
those QSOs will not count for ones personal DXCC records.
I need to isolate if a problem I am having is in a faulty 75 ohm coax
(Remee RG6U flooded variety) where either a critter bit into the coax
or a Snap--Seal 6QS connector failed, or an electronics issue is the
culprit.
What's my most expeditious way to prove if it is or is not the Coax?

Hi Bob,
You could use a vacuum relay and key it from the keyer or rig line that
is timed keying (such as for an amp). You want it open when transmitting
of course.
Might even be able to use a smaller non-vacuum relay such as the PC ones
used in Top Ten and other relay boxes.
Also can put
I have an 85 foot shunt fed tower that I use on TB. I have a HI-Z 4
Square
and some short beverages. The performance of the RX antennas definitely
improves (less noise and better directivity) when the TB vertical is
shorted
to ground. What is the easiest mothod to short the vertical to
Can someone explain why grounding the feed of a shunt fed tower
prevents it from re-radiating noise? The tower is already grounded.
I don't understand how grounding the coax port looking into the
gamma or omega match accomplishes the goal.
I've been trying to get my shunt fed tower to stop
So, depending on what your radio main antenna port looks like when switched to
receive antennas, you might be able to add 1/4 wave of coax and have exactly
the
same effect with no additional switching at all.
Otherwise, you run a risk of creating relay sequencing issues. You have to be

I need some opinions,
What is the best acquisition between Timewave ANC-4 or MFJ-1025?
Thanks for help me!

Hello to all, I have been reading for some time and never had anything to add
until now. I have learned a lot and want to thank all of you for the valuable
information.
To protect my coax from squirrels and the weed eater... I use 3 perforated
drain pipe. I saw a cut down the back side and
Hi Folks,
I am getting ready to put up a Hygain Hy-Tower and plan to strip all the
stubs off it and use it as a dedicated 80M/160M antenna. I would
appreciate some pointers to websites or other sources of modification
information describing methods to make the Hy-Tower work well on both
bands,
An alternative would be to use BNC females and an adapter to go from the F
male with a male BNC on the other end. I have a of them without any issues.

Here is Toms review on the MFJ-1025 along with his modifications to improve
it. After doing the mods and using it extensively Im totally happy with it
used only on Beverages and BOG's and have no BCB problems.

I use F female to BNC male adapters in the shack with all RG6 cables
terminated in F connectors. I have gone completely to flooded RG6,
matching connectors, and, yes Virginia, the particular tool for those, from
DX Engineering.
I just haven't found anything better than the F connector for
I had to work them 3-4 times to get a good RTTY QSO. You would think I could
achieve DXCC-K9W-N.I.L-All-Band. Finally got as good one for that mode..

What is the best acquisition between Timewave ANC-4 or MFJ-1025?
While all of them will work, the Timewave phase adjustment causes a huge
change in level. It also has less phase range. That is bad, because you have
to go back and forth between the controls more.
The phase should really
Same here. I second Guy's observation.
And I regularly run the legal limit through my F connectors, and
occasionally the legal limit with high SWR! Yet, they don't even feel warm
to the touch afterwards.
I always make certain that the copper is nice and bright. And on either

Thanks for the replies. I do have a 259B I bought off of fleabay
several years ago no manual came with it. I only wanted it for SWR

I just downloaded the manual on PDF and read the advanced section
What is making you believe you have a faulty 75 ohm coax?
I would hang a 50 ohm dummy load on it at the end of the cable that goes to
the antenna and load it to the same power level you have the problem with.
Then move the dummy load to the next joint then the next joint and so on
and do the
A clarification or two, sorry for the confusion.
First, I only use the F connectors and DXE flooded RG6 for RX, though I
can see putting some amount of 160m power on them, I just don't do so
myself. There's a part of me that just cringes at the idea of a KW on an F
connector. Same guttural
I'm trying to eliminate issues with my Rx array and I'm getting
birdies that are not heard on the main antenna. If the problem is
faulty coax/connectors due to bad work on my end or the help of tree
rats that didn't run at the smell of coyote urine then I have my
answer. If all is well on my
