Re the overload concern with active 4 sq receive antennas (although the 
IP3 is quite high for DX Eng and Hi-Z).


For the upcoming Mellish DXpedition  VK9MA, the team leader Rob N7QT 
asked if I could help build a passive 4 sq, inspired by a comment from 
K3LR and some ideas from http://www.w5zn.org/160%20Meters.html .  The 
VK9MA overload concern with active antennas is 4 simultaneous QRO 
stations on a couple of acres of sand, all verticals.   With generous 
support from DX Eng. for the Hi-Z boxes, chokes, bases, and aluminum we 
built a passive 4 sq with top loaded whips, see W8JI for the antenna 
design  (25' whip, 4x 25' wires at 45deg, 4x 54' ground wires each).  A 
simple tuner box is needed at each antenna, some switchable L to 
resonate on 160 and variable R to load and match 75 ohm cables.  We 
don't know the VK9 ground conditions so they will tune the antennas on 
site, but they tuned easily to 1:1 with a SARK in my front yard.  There 
was almost no interaction in the tuning with them all up.  Each whip was 
connected without amps to the Hi-Z phasing box which had delay cables 
cut for 70' on the square side. Then with 70 to 50 ohm transformers and 
50 ohm 160m low and high power bandpass filters overload should be 
manageable, we hope.  We had the chance to test a little bit and saw 
expected F/B etc against a daylight BCB station just in time to ship to 
VK  land (Cairns) staging.   vk9ma.com


Fingers crossed that it helps the 160 effort  at VK9MA.  They will also 
have some DHDL's up, proven winners on prior DXpeditions.

I tied that once with a couple of radials on the ground.  It was 
terrible.   I think K2AVs folded counterpoise is probably a good 
choice for those on city lots and don't have a lot of room.  He seems 
to do very well with it and others that have tried it report the 
same.  I haven't tried it myself.  If you do that, be sure to 
construct it exactly as he describes. The operation of that system, 
especially the transformer, is not obvious.**

**Receiving is always a problem on 160 and it makes a huge difference 
in working someone if you can hear them well. Noise from a city is 
difficult to solve when you live in or near a city.  Best solution is 
to clean up the noise from your own house and find a way to put up 
some kind of receiving antenna. That can also be difficult when you 
don't have much space. **

**
**If you have local noise from just one direction, a receiving loop  
can be used to null that.  If the noise comes from all directions or 
is atmospheric noise, a loop won't help very much.  The first level 
of receiving antennas consist of the single element loops, like a 
K9AY, flag, pennant, delta, diamond, etc.  Those all perform about 
the same because they all work like two short phased verticals.  The 
main difference between those is in the effort to construct them and 
the difference in their susceptibility to common mode noise from the 
feedline (which is always a major concern with low gain receiving 
antennas).  Note: The K9AY is the easiest to construct if you want 
the capability to switch directions. The ones that use a ground rod, 
are easier to control the common mode noise.**

**
**There is an antenna called a double half delta (DHDL). Put "DHDL 
antenna" into Google and you will get several hits. It takes up a lot 
less space than a BOG or Beverage and works very well.  It works best 
when that bottom wire is near the ground, maybe about 2 ft from 
ground.  That is the only thing I don't like about it.  This antenna 
should beat a short Beverage or BOG.  They come in various sizes.  
You will need two supports of at least 20 ft high to construct a good 
one for 160.**

**I have been playing with BOGs for years and they are good receiving 
antennas, although they may be too long for a city lot.  I have tried 
various lengths and found anything between about 200 ft to 370 feet 
to be good on 160 and 80.  The shorter end of that range works a 
little better on 40. I live in a rural area and don't have a city

Re: Topband: 3C0L (FCP)

[Mike VE3CKO]

ok, the details. The vertical originally was an 80m vertical comprising 
of a 20' 2" OD mast with a 40' spiderbeam mounted on it. Three 14 gauge 
wires were attached to the mast fastened along the spiderbeam, about 17' 
up the spiderbeam there was a loading coil made from 1/4" copper tubing 
and then the 3 lengths of 14 ga wire to the top of the spiderbeam. 
Worked pretty good on 80m with the K2AV FCP.  While soldering the wires 
on each end of the loading coil, I did this when it was fastened to the 
spiderbeam. This was a mistake as the heat must have damaged the 
spiderbeam at that point. It lasted just a few months, the spiderbeam 
snapped at the point. So what was left was the 20' aluminum mast and 3 x 
14ga solid copper wire supported by about 17' of what is left of the 
spiderbeam.


This is nothing special, no majic certainly nothing resonant on 160m but 
as a receiving antenna it is a good 3 S-units less noise and other noise 
from what must be plasma spikes or whatever in the surrounding 
neighborhood are also dramatically reduce. CW and LSB too noisy to hear 
are very readable.


Using a Flexradio 6700 the noise floor on inverted-L is at the minimum 
S-7, with this vertical/K2AV FCP  it's just under S-4. I must also note, 
my homemade 80m double bazooka works well for a receive only antenna for 
160m  about S 3.5 and it is directional so it pull out state-side 
station better than the vertical. I do have an Antenna Genius 8 x 2 that 
does make it easier to play around with various antennas.


I've had some good success in the past with my Flexradio 5000 using 
diversity on this band but have yet to play around with diversity with 
this vertical.  Still too much noise to hear anything across the pond, a 
move out to the country should help with that, we'll see.

Hi Mike,

My only 160M antenna is a bent inverted L with a loading coil in the center
of the vertical section, and one elevated radial. I live in a residential
neighborhood and my noise level is so high I could not hear 3C0L on 160M.

But, I did work 3C0L on 80M using a slightly loaded 80M vertical and FCP for
both Tx and Rx.

Noise floor at my QTH in the city is just so high with the inverted-L and

Re: Topband: 3C0L

[Kenneth Grimm]

I also heard 3C0L well before sundown and called for about 30 minutes.
Realizing that he was only coming back to Europeans, who were undoubtedly
much louder than I was considering that they were in full darkness and I
wasn't.  I watched TV for a while and when I heard them beginning to work
the US, I got interested again.  Another 30 minutes and I finally got
them.  This doesn't surprise me as I have wasted many kwh fruitlessly
calling Europeans before my sundown.  While I could hear them, they
obviously could not hear me.  I now tend to be much more patient and wait
until the mass of European big guns have got their QSO and the sun is well
down before calling.  Yesterday afternoon, I forgot my usual habit and
started calling when I didn't have a chance...an ATNO has that effect, I
guess!

Conditions were very good for the entire evening and I'm sure a very large
number of stations were able to get their contact.  The superb operating by
Yuris didn't hurt!  I will be interested to hear whether they were running
barefoot with the K3 or also had the SPE amplifier going.  They obviously
got their generator problems sorted out as there seemed to be continuous
operation.  Good conditions, good equipment, and a good operator is what it
takes for a successful expedition. Only two out of the three usually means
that the lids have much more fun.  Speaking of lids, I can usually forgive
the KC cop who sends "up" when someone forgets to push the split button,
but what gets my goat is the particularly vile person who gives a fake
report and the unsuspecting op believes he has made a QSO.  That kind of
behavior stinks!

I hope conditions continue to be good and those in the mid-west and west
manage to get their Qs.

Re: Topband: 3C0L

Great job by the 3C0L on 160.  They logged about 900 Qs last night on 
160.  They started slow but picked up steam later.  I can only imagine 
what that enormous pile must have sounded like on their end.


Also started hearing them 1 hour before my sunset, although weak at that 
time.  Later they peaked at about S7.  Typically ran S3 to S7 all 
night.  Solid copy from my sunset until their sunrise (except for the 
QRMers)  I wonder about the details of that short 160 antenna. They 
really had it playing well.  Best receiving antenna was a 365 ft BOG 
pointed right at them.  Normally my best receiving antenna is my phased 
EWEs but those were pointed at 45 degrees off them, so that's a 3 dB 
signal to noise loss, and the BOG was better.

I got them on 160 last night as well.   They were loud but I was fighting 
significant QSB going between loud/solid copy and no copy at all within 
minutes.   He may have come back to me once or twice but I wasn't sure due to a 
QSB fade, then another time someone tuned on top of him but it would have been 
ESP if it was.After about 45 minutes or so I gave up for a bit.   Went

I would agree on the huge pileup and very very poorly behaved.  I guess people

He was decent copy and then would dive into the noise and come back.  I just

K0EU got them and maybe AA0RS but I didn't hear many others in the area get

Re: Topband: 3C0L

[W0MU Mike Fatchett]

I would agree on the huge pileup and very very poorly behaved.  I guess 
people still can't copy their own calls.


He was decent copy and then would dive into the noise and come back.  I 
just got my 8 element circle back up but I am not sure it is operating 
right as sometime they were stronger on the Inverted L.


K0EU got them and maybe AA0RS but I didn't hear many others in the area 
get him.  I never did.

3C0L had superb signals on 160M last night and a ginormous pileup.

Their signal started out an hour before my sundown, on my NE-facing K9AY
loop, but began showing QSB there an hour after my sundown. I then checked
and was surprised their signal was so much better on my transmit antenna.
This is something I've noticed several times on African DXpeditions.

I wonder if "Looking to the NE" makes sense before sundown because this my
shortest path to the most darkness, but the further after sundown a more
direct E or even southerly path makes more sense.

Topband: 3C0L
