Picked up an A/S M184 from Italy yesterday. Unused condition,looks interesting. Also got a 2 piece A/s MS90 2 piece mobile fibreglass whip nos. Can't wait till they arrive.
Only bandpass filter I ever saw or used was made by Jim Finch of SSE Electronics.
Don't think they are still in production as last time I was on Jim's website they weren't there, they were 26-30mhz and 300w power handling and very well made...
BB809 will do it too.

Nice to be back Jeff. Not been too great recently but some things never fail to cheer me up. Might go into production of these. Add a few led's as suggested could be the audio gainer of all time. Especially with a quick coating of tartan paint and copious amounts of swr grease. Lol. Hope you're...
I'd be careful rg58c/u is marked with mil-c-17f/g or M17/28.
I'd avoid anything that says rg58 type.
And so you can solder the braid properly I'd go for amphenol 83/822 or amphenol 83/1sp both with an amphenol ug175 reducer.
If body/tip is nickel plated file tip or holes to base brass and tin...
I smell obscene amounts of copious bullshit.
My wee hp4000 only has 12' of mil spec rg58 on it and has banged into s.africa.oz and all over s and n america. Surely I wasn't dreaming and running an underlegth coax run.
Wonder how many mugs will buy it. Lmao.
Couldn't agree more mate.
Sometimes a bit of humour/sarcasm can lighten the mood.
The written word is very easily misperceived, especially when in heat of moment you forget to add a wink, smile, tongue out etc.
What was a minor disagreement or calculation can soon blow out of proportion.
I...
Lol.
I know its coincidental as you say. But in saying that makes you wonder how many other things taken as fact in radio are purely coincidental too.
Sure you were only inches out and to be fair arithmetic is a much bigger strength of mine than radio theory.
You pulled me about using ch20...
I'm well aware the velocity factor doesn't affect the shield outer was merely an observation that both chokes contain an electrical 1/4 wave of coax or thereabouts.
I'm also aware of what the turns do.
I notice you omitted the bit that your figures are wrong ;) lol :)

I get slightly different figures.
for diameter your measuring to centre point of coaxial on either side of core. In effect measuring the diameter of the cable itself.
Using 5mm/.19" rg58 I get rounded up.
3.14 x 4.25" + .19" = 4.44" x 5 turns.
3.14 x 4.44" = 13.94" x 5...
Sorry I haven't had time to read Henry's report, comment or answer messages.
I have been quite ill recently and had a bit of a fall early last week that resulted in an unscheduled collision with a glass tv stand, a floor standing speaker I decided to glasgow kiss on the way down and a collision...
Maybe if you look in right place you'll find schematic.
Go to servicedocs.com search by brand dropdown. Select President and scroll down to Grant 2 schematic. As well aa schematics/user manuals and service manuals for most European Presidents ;)
Would love to go to Geraldton. My aunt lives there. Emigrated years ago and never came back. Not that I blame her. Xmas dinner on the beach or sitting next to an eskimo in Scotland. Fucking tough choice. I should have emigrated there myself 6 year ago when I got offered.
I imagine the local qrm...
Hi Eddie.
I wouldn't say its impossible to make antenna comparisons. I just think its very hard to make accurate measurements, especially using seperate masts.
the s meter will show relative increases/decreases of signal levels but not accurately. Backing it right off could be as bad as...
