Re: RE: [AMRadio] Valiant and Loop progress
Brett, Put the 80 and 40 dipoles together, ie common feed point, and let the ends of the 80 dipole hang down at the ends. Hang the 40 dipole from the 80 wires using a bit of nylon rope for the first tests. You can make a permanent setup with insulators to support the 40 after the initial tests to get the lengths correct. Make a choke in the feedline at the top by wraping 8 turns or so of the coax around a 6 inch diameter plastic jug. Trim the length the 80 first then the 40 and you can get the SWR low enough for use without a tuner. It won't tune to 1:1 so settle for less than 2:1. I have a 80/40/20 web of dipoles fed with coax on top of a 35 foot tower that works good. 73, Larry K2LT > > From: Brett gazdzinski <[EMAIL PROTECTED]> > Date: 2005/12/06 Tue AM 01:13:10 WET > To: "'Discussion of AM Radio'" > Subject: RE: [AMRadio] Valiant and Loop progress > > While on the subject of antennas, I wonder if anyone knows of a way > to do what I want to do. > I had a resonant 80 meter dipole above the house, the length was only > about 90 feet, so I had loading coils about 3/4 of the way out from the > center. > That worked ok for years, but the coax went bad at the feed point, and > while the antenna seemed to work ok, I had a bit of RF in the house, since > it was lengthwise over the entire house. > > I have a resonant 40 meter dipole that runs at right angles to the house, > and most of it is over the back yard, no RF in the house. > > I likely have about 90 feet there also, if I stay out of the trees. > > I would like to have one antenna that is resonant on 80 and 40 meters > without an antenna tuner, that fits in the 90 foot space. > > A trap dipole would be nice, but I have never found anything that holds up > to > AM at any but the lowest power levels. > > I normally run about 300 watts carrier on 40 and 600 watts carrier on 80. > > I made the mistake of trying one of those B+W all band folded dipoles, the > lowest > swr I could get about 4 to 1, maybe because of the close trees. > They are also only good for low power on AM. > > The next experiment was as much wire as I could fit above the house, about > 42 > feet each side, fed with open wire line for about 10 feet, then to coax. > The first test showed the swr way off, so I put the antenna tuner on, and it > > started arcing.

[AMRadio] 80-40-20 meter AM transmitter for sale
As part of the process of thinning down my collection and cleaning up my mess I have elected to sell a homebrew (not by me) 80/40/20 meter AM transmitter. It can be seen on my website (http://home.comcast.net/~wa5uek/index.html) or at my home QTH. The final, modulators, iron and cabinet are worth more than the asking price, which is bascially how much I have in this rig. Thanks for reading, Brian K. Harris, WA5UEK Email:[EMAIL PROTECTED]

John, I'm working on a Vaiant* for a friend, and I ended up using eight 680pf @ 1KV in series-parallel (4 parallel pairs in series). The caps I used were the CDE "snubber" caps, available from Mouser. Between these and the analogous 40 meter fixed caps, it the total was around $60.

RE: [AMRadio] Valiant and Loop progress
The yard is about 160 feet on all 3 sides, and is shaped just like a slice of pizza. The house (brick ranch) sits half way, the front is a street (crust). There are a lot of trees, but most are close to the house or lower. There is a big oak at the tip of the slice, but that is only going to get me another 5 feet, and its not as good of a support as the cedar. The wire would be in the branches, the cedar is compact... I don't want to put anything on the roof, the chimney wont support anything, and its off to the side. I know the way to go is to put up as much wire as I can and feed it with open wire line into a tuner, but I don't want RF in the shack, or have to tune up an antenna when I switch between 80 and 40. I have separate stations for 80 and 40, so no tune up needed there. I once tried the open wire line into the heathkit antenna tuner, and it just smoked the crappy balun, I would have to build a real balanced tuner. Tricky to build one that is shielded and adjustable...

solid state mixing with tubes.. I tried to fire up an old tube linear for test with an Alinco DX-70.. The Johnson Viking I usually use for this was not within reach and the DX-70 was. Unfortunately, there was a DC connection between the GG amp cathodes and the RF input jack. Somehow this fried the Alinco and blew the fuse on the linear.. I think when I did the forensics on this one that when the Alinco un-keyd, the amp was still keyed and 300VDC appeared momentarily on the RF input jack -still not sure why, but it did.

Re: [AMRadio] mike hu-m-m-m-m problem
Many thanks for your very detailed and useful reply, Jim. I was sorta hoping this could be dealt with with a wad of aluminum foil, but :-) . I just read a broadcast engineering publication review of a couple of Heil mikes. Sonic quality and "value for money" ratings were high -- but the reviewer did register a complaint that these Heil models did not incorporate a hum bucking coil and were, consequently, prone to noise pickup from nearby power supplies. Simply moving the mike far enough away from the hum source cured the problem, but that's not always feasible. I do have a roll of 4-inch wide Mu metal, so I could fashion shielding, if need be and I'll look into the more complex solutions you recalled if I must. However, I did, in fact, buy a good old D-104 from an eBayer this morning just in case all else fails :-) . Every vintage shack should display one anyway. 73, Craig W3CRR

Re: [AMRadio] mike hu-m-m-m-m problem
Craig, If the problem is the mic element picking up stray hum, then moving the mic around will vary your symptoms. Do you see that? If so, you can use the mic to zero in on the source of magnetic flux. Steel, or preferably Mu-metal (the stuff around oscilloscope CRT's) can offer shielding from stray flux. Here is a silly thought; remember an old photo in the ARRL handbook where a car distributor cap was shielded with a large tin can, and then copper braid was added to shield each plug whire, and was soldered to the same tin can? Doing something similar to your prize mic might help, or go back to an Astatic D-104. That crystal element is immune to this problem. :-) More seriously, maybe you can find the source of flux, and eliminate it at it's source. For example with my QRO 20A I had hum in the nulled carrier (120 hz) that was much worse after adding a filter choke (open frame)to the power supply. The flux from the choke was coupling through the metal chassis, and into the two modulation transformers. The fix was to replace the choke with another that was enclosed in a steel case. Problem was solved. I could have also tried to change component orientation, but limited real estate to do so did not allow this option. I still had some hum in the carrier null but this was 60 hertz. I added a hum neutralizing circuit to buck out the hum in the proper phase, and magnitude. In the end with a 6.3 vCT filament circuit, I used 20 ohms to inject current into the balanced modulator diode support bracket. The carrier null was now without a measurable 60 hz component. I hope you resolve the huuu issue with that nice Heil microphone.

[AMRadio] mike hu-m-m-m-m problem
I'm having tons o' fun with my "new Collins 32V-2, BUT, I've got a hum problem. According to several listeners, my Heil Classic microphone -- while sounding great otherwise -- may be picking up EMI from the nearby transmitter iron. The mike has no internal humbucking coil. Has anyone else experienced this problem with dynamic mikes and heavy iron? If so, how did you solve it, please? Many thanks and 73, Craig W3CRR

Re: [AMRadio] Valiant and Loop progress
John, I wonder what your loop looks like at the feed point to your tuner. Do you have an impedance analyzer? Just curious. As for me, I like to steel ideas from those that have already been there, and done that. Once such example is at: http://www.sirinet.net/~mars/hor_loop.pdf Since you are modeling this antenna, consider the counterpoise as described in the PDF file. Maybe this can be attached to the bottom of your fence with periodic 4' ground rods every 30' or so. I'd be curious if this helps either with Eznac, or actual usage with your loop. Also since you have a 35 foot tower up already, consider that as a means to support say a 3/8 wave inverted L for 80 meters (3/4 wave on 40) with a single wire counterpoise in your fence. With the current maxima up high (80m), and dual polarization, good all around performance is possible. This would be a 30' vertical, and 60' horizontal sloper down to your fence. This wire will be nearly invisible if you use a small gauge wire (maybe 22 awg). Good luck with the "taming of the shrew (Valiant)".

Re: [AMRadio] AM Exemption Already Drawing Fire
I applaud those 3 for even trying to bring a point into a den of discussion that mainly comprises personal agenda and typical ARRL bashing. I think I'll sit back and see what the FCC's action is on this proposal and the one that was already submitted in June. The FCC has already indicated that the present Part 97 rules lack clarity and, in some cases, impede the operation of new modes on our amateur bands. If nothing else, I'm sure over the next several years, we'll see changes made to various sections of Part 97 governing our amateur service. The dabble on QRZ just adds to the amusement.

Brother, you ain't got started good, yet! ;-) Wait till ya try interfacing tube technology with solid state stuff... took me three days to figure out that the plug was wired backwards, and the collector output, that was supposed to be on the ring, of a 3-circuit plug, was actually solder to Ground, and the ground from the computer, was soldered to the ring. No WONDER it keyed up, as soon as it was plugged int... ... and I've been doing this a while...

[AMRadio] Valiant and Loop progress
A dozen folks have written me, privately and on the List - with advice about my loop antenna. The consensus is: it doesn't matter much - so I connected the balanced feedline to the loop with no 'spread'. First off - there have been a couple of 'why do you want to do *that*??" questions - and the answer is of course - brand new housing development, and CC&Rs. Now, here in No. Nevada - folks are pretty much live and let live - and I do have a VHF/UHF stick up on a 35' pole - but putting up a 'real' antenna is not a good idea... so I have run mine around the perimeter of my back yard, just under the top of my 6' wooden fence. Until I shift QTHs - perhaps as soon as this spring - this is what I have to work with. I had considered an all-band vertical, and have owned a couple of Butternuts in years gone by - but the Loop must do for now. At 100W RF output on 80M - the Loop is tunable to 1:1.1 using an Ameritron ATR-15 tuner. Before I had a chance to try a Real QSO on that, or any other bands, the Valiant puked up Yet Another Capacitor. Which brings me to: The Valiant. I have recieved much helpful advice and experience from many folks as I have been involved in electrically refurbing my Valiant I. Of course I couldn't have finished the Project w/out the help I have recieved - so my thanks to all of you who have been so kind with your advice and experience!! And this much I have learned: just because a capacitor is a certain value and voltage, doesn't mean it's going to be able to stand RF current... ;} There is a fine reason the Johnson engineers used the capacitor configs they did in the pi-net and coupling circuits - it's the "divide and conquer" strategy. Now, I imagine a few folks are rolling their eyes and saying things on the order of "No shit, Sherlock!" - but I have next to no RF repair or design experience - most of my work professionally and privately has been in audio and music and film systems... even hi-power PA-amp output coupling caps don't have to stand the gaff that occurs in RF work. And even though I rebuilt the bandswitch stacks twice - I didn't use the topology that existed - two 'series pairs' in parallel - mainly due to not having the right units and to getting 4 350pF micas that are marked on the package "350" - the color code is '350' - but they're 560pF every one of 'em. No wonder they were surplused! Imagine the hours of Fun that caused... now I just check 'em no matter what. So the Valiant is putting out 100 - 130 watts into my load or antenna on all bands - I put it back in it's cabinet (mistake..) and cabled it up. Having previously set the mod bias, I tuned 'er up, opened the Audio pot, gave a couple of whistles and the 160/80 M capacitor stack "deviated from spec" in a rather spectacular and stinky fashion. O well - at least I understand completely what needs to be done - and about $60 worth of the correct RF units will be delivered to me on Tuesday. Wouldn't have been so much, but I bought heavier than required and also spares, just in case Thats where it lies as of this Weekend - if I have paid my dues sufficiently I oughta be on the air by the weekend - and I'll be happy, until I set my fence on fire - snowing or not. ;} Cheers John KB6SCO
