Subj: In Attic Dipole

I made something that is fun to play with! I got 2 Hamsticks for 10
meters and mounted them end to end horizontally.
Voila!  A cheap rotatable dipole.  mounted at about 35' I had a 1.1 to
1.5 swr across most of the band.
 
I took 2 mirror mounts and bolted them to a length of mast and secured the 
center conductor to one mount and the braid to the other. I then came down 
about 2-3 feet and wound 4 turns of coax at about 6-8 inch diameter.
Then fed it right into the radio.
At such a low altitude, it does seem to be very directional.
Gonna try 20 and 40 meters also. Will post results as i get more 
exposure to this antenna.
 
Cheap, easy and (apparently) effective and very compact.
 
73 and Happy Holidaze!

Hi Ivy,
II->Actually, I haven't seen another program that displays like STSPLUS...
II->it's about as close to the big wall-sized whole-world display in Mission
II->Control - and do it full-screen - as it's possible to get on a computer
OK, suit yourself.

Hi Jeff Edmonson, hope you are having a nice day

PW>>right nice on 80.

 Hehehe... Check the CALLSIGN echo.. hehehe... If I read the knobs

PW>>  The thing is, is that the electrolytic caps need time to reform.
JE> If you've already had the thing on, and working, they've reformed.
 So its go or blow huh. Seems that may have happened in the hallicrafters.
There's these black cylindrical caps with waaayy to many color bands,
and a few of them have the insulation/encapsulant split radially down the 
middle.
NTM the ooze I found in the bottom of the cabinet.

 Whew. It's a bit early for fireworks for the new year. <G> And way too

PW>>old caps? Ie. maybe run it for 30 - 60min a day, and leave it off 
PW>>the rest of the time.
JE> Even that wouldn't have done it.
 Okey doke. Filed away for future reference.
JE> What you should have done was to bring it up, to around 25v on the

JE>100v (same waiting time), then up to normal line voltage.
 That's what I had in mind, but getting to those variacs.....
And I've a couple that are just the size for rigs like this one.
Shoot, it only calls for a 3A fuse. Lucky me, the replacement
fuse holder already had a 3.15A in it.
 As a side note, I dug around and found a replacement tube. (6AQ5A)
Plugged it in and fired it back up, (not turning down the audio knob)
and rather quickly introduced my left eardrum to my right. =8{#
 Dat's a lot of audio to be 1W.

6AQ5's are some dynamite little audio tubes.  I use 'em here, to drive 6L6's, 
807's, 5881's, 7868's, etc...

 I'm getting ready to do some major dumps of stuff the week before X-mas.
 I'm also updating the "Find the Jammer" file I wrote 4 years back.
 I've just started getting into playing with the APRS software for DOS and
reading up on how an APRS system can be used to do RDF-ing.
 That was the major reason for the new Jammer finder post re-write.
 The idea of using APRS for DF-ing a jammer is something new for me,so I have 
been doing lots of reading on it in the docs that came with the software and
some tesing with a couple of other amateurs here who are trying to set-up a 
mini DF group using APRS.
 The post will be in three parts with the last part being on APRS DF-ing 
sing
the DOS version of the APRS software.
 I should have it finished sometime this weekend. (I hope!)

Subj: j-pole ??

 SB> Hello all you Brilliant antenna experts!! :-)
 SB> I recently saw a j-pole antenna that ground radials on it.
 SB> Any idea why they would do this?  I think it was being used as a scanner
 SB> antenna.
 Stan if the J-pole "goundplane" radials were 1/4 wavelength it would help to 
improve the omni pattern of the antenna.
 Although the J-pole is supposed to be an omni antenna radiating equally in 
all directions,it can be "aimed" by facing the stub (the J element ) in the 
main
direction you wish to talk the most.
 The radials are being used to add a groundplane underneath the J-pole and to
improve its radiation pattern to a more omni one.
 For fun try rotating the J-pole to point/aim the hook of the J element in a 
direction you can normally hear only weak signals and see what happens to the 
recieved weak signal.
 You should see the weak signal increase in strength as the J is slowly aimed 
at the source.

 Paul if you can get the MARS/CAP mod info just reverse it.
 The Yaesu FT-212RH should already have the wide band recieve in it from the
factory and all you need to do is reverse the MARS/CAP TX mod to get 2m TX
only.
 If you can't find it let me know and I'll see if I have it here somewhere 
and send you a copy via netmail ro E-mail.
 I collect modification info as it always helps to know how the modifactions
are done for a given chassis,to be able UN-do them after someone goes playing 
around in a radio.

Hi, Stan;
 
 SB> Hello all you Brilliant antenna experts!! :-)  
 SB> I recently saw a j-pole antenna that ground radials on it.
 SB> Any idea why they would do this?  I think it was being used as a
 SB> scanner  antenna.
 
Hmmm... there is no need for radials on a J-pole!  That's one of the
beauties of the design.  It's all above the base.  The only counterpoise
it needs is in the short "J", which is actually a matching section.  The
only reason I can think of to have radials on it would be if it were
either multiband, which isn't necessary, since most monitoring activity
is either around 150 or 450 MHz, which is the third harmonic of 150, and
J's work fine on 3rd harmonic.  (I have used my 2 M J-pole on 70 CM with
great results).  The only other reason I can think of to have radials on
a "J" is to make people THINK it's a better antenna than a "straight J"
so they can get more money for it.
