Thanks for the reply, very interesting. I am considering to convert it to a director rather than a reflector. Its kinda disappointing while pointed and talking to Australia (west) at 9 s units that folks in Wisconsin (east) can hear me at 7. The back end of this thing is nearly wide...

Looks like a DC blocking capacitor, Is there voltage on the white wire at the radio mic socket??

I've got one of the oldies SP1a processor from clear channel I use in my old school President Lincoln...MRF 455...Works great.

Looking for an Orban Optimod HF 9105A or an Orban Optimod AM 9100B. The 9105A is preferred.

Welp, the hairpin didn't work, well it did with shortening the boom length but that did create different issues as mentioned above. I ended up just playing with the boom length at around .225 wavelength then the driven and reflector element lengths. Worked out pretty well with 1.09:1 swr and...

Well, You don't KNOW everything and what you think you KNOW is incorrect! We talk on the phone about radio repairs. I am a repair tech. I've repaired and modified more than I can count. We have talked about the 8920A service monitor over the phone as I have one sitting here too and I know how to...

You don't mean to be confrontational??? Well you certainly are. Everything in my post is true with 1 mistake. When I said he was on invoice 5008, I meant that is where he was when I ordered the radio. So, if you don't like hearing the truth about something that's got you all butt hurt...get over...

Actually it will be 2 years this coming January Chris. My invoice is number 5601. He said he is just now up to invoice 5008. so about 600 radios till I get mine. He calls me often and we have talked for hours. He's actually a pretty nice guy. Never talked down to me, insulted my inelegance or...

Wanted in good operating condition.

Don't know if it's true but I heard it was a solar flair that may or may not have been ejected. I think it might have been from the Space Weather Chick... Tamatha Skov.

Polyester resin or gelcoat. You can use a green 3m scrubbie to sand it down. Yes, definatly wear gloves...fiberglass slivers suck. What ever you use make sure it has a UV blocker or buy the UV blocker additive. If you use gelcoat make sure you add surfacing agent or it will remain sticky...Made...

Well, I pulled it out of the circuit. It's actually 100 pF not 91 but it tests at 225 pF. I did order from RF parts a few metal clad 91's and 100's but they're 350 volts...might not matter the voltage??

I need to replace the 91pF (C45) metal clad mica capacitor in my dx500v. Anyone know the voltage rating of that cap??

Yeah, nah...the tinySA's aren't that good...at least the one I had for a short time wasn't. Bought it for a stand in while my HP8920A was out for calibration. No comparison...

Welp, I finished the beam today...sorta. 2 element driven with a reflector and a 1:1, double toroid 240-43 common mode choke with 1" to 7/8" element taper. reflector is bonded to the boom. It worked out pretty good with a 1.05 vswr, +3 reactance and 52 ohms. I'm gonna work on it a bit...

Well, I built the hairpin last night. Building the 1:1 choke today. I've got most of the hardware and all the elements to complete it. Gotta find a 2" aluminum boom. From the get go this project has turned from just a rotatable dipole to a 2 element with the expectations of turning it into a 3...

I'm building a 2 element yagi with a direct fed isolated split driven element. I would like to feed it with a Hairpin match and a 1:1 current choke. All the hairpins I have seen are on a beam of 3 or more elements with the hairpin rods facing the director elements. Can the Hairpin rods face the...

A moxon is a fine beam. A local across the line in BC has one that talks all over the place. We're 12 miles apart and when on the vertical here when he's pointed at me on the flat side I hear him at about half the signal as when he's on his vertical. When he points it SE or SW I can barely hear...

Thanks for the help. I'm making a new beam out of my old 4 element that came down many years ago in a north easter blow.

Is this all for gamma matched driven element or a direct fed driven element or does it matter??
