    Subject: Re: King KR-86 Loop Cable
    Thanks Bob, I have the service manual, but there is no hint of what the capacitance or impedance is of the loop cables. It does show the cable as 2 separately shielded 2 conductor cables. The install manual gives 2 part numbers of cables (different lengths) and also says to not alter the length. One is 15 ft. and one is 24 ft. I bought this radio and antenna at OSH for, I think, $25. I repaired the radio -- found a leaky capacitor in the synthesizer loop filter which caused a loud 1 KHz noise that covered up all signals. This is just a hobby project, so I don't want to spend lots of money on it. I've already spent twice as much on manuals as the radio cost! I am a EE, and have been a ham for over 50 years, built a lot of equipment, etc. There should be a way to solve this problem, but so far I haven't been able to! I'll try some things -- like measure the antenna inductance to get an idea of the impedance we're dealing with. I can also make some measurement on the goniometer, and front end coils that it feeds. That gets a little complicated! Thanks for the help. If anything else comes to mind please let me know. Dan In a message dated 2/8/2012 7:47:36 P.M.

Apparently the capacitance of the cable is critical. Can anyone tell me what this capacitance should be and how to measure it? Also, is the cable 2 separately shielded twisted pairs, or can the twisted pairs both be in the same shield, like telephone cable? Not sure without schematics and a service manual. There have been numerous service bulletins over the years that called for confirmation of a sense or loop cable assembly's capacitance. For many radios of the era, coax capacitance was an integral component of resonant or reactive circuits within the receiver. I recall writing accessory kits for ADF installations wherein the installer fabricated a sense antenna coax from some weird coax with a very tiny center conductor in a relatively large hollow insulator sleeve. Car radios used to use the same stuff . . . very LOW capacitance/foot was key. Here's a tid-bit I found on the 'net about low cap receiving coax: The real reason car radios used ~90 ohm coax is 90-95 ohms works out to be the very highest impedance practical in a coaxial line having minimum possible shunt capacitance and reasonable outer and workable conductor size. This is entirely because of the short unloaded whip antenna on the car, and the AM broadcast bands low frequency that makes the antenna the tiniest fraction of a wave tall. The small car antenna is a voltage probe on AM broadcast. The short car antenna is an extremely high impedance source on the AM band. The AM receiver has a very high input impedance, ideally hundreds or thousands of ohms. Any shunt capacitance to ground in the connection between the receiver and antenna forms the lower leg of a voltage divider that reduces the RF voltage available at the AM radio input. The car system is not operating in a normal transmission line mode. This type of cable was also used for some old data lines, and it can work as a transmission line, but generally it is pretty lossy compared to other cables. After all, nearly all HF and VHF loss is caused by conductor resistance and this cable has a pretty thin center conductor. As the article states, coax used in this application is not behaving like a matched transmission line but simply a shielded wire chosen to minimize the upset for very high impedance receiver front ends. RG62 is the only modern coax I can find with a low capacitance (13.0 pf/ft). You could probably make a new cable from this stuff if you knew what the total allowable capacitance was . . . this sets cable length. These folks offer cables for KR-76 in various lengths. Perhaps they fabricate them locally. _http://www.bennettavionics.com/kr86system.html_ (http://www.bennettavionics.com/kr86system.html) Bob . . .

It reads your "forward" and "reverse" power in watts. So it is both a test of your transmitter's power output and a display of antenna/feedline quality. I'll run to the Post Office in the morning. I'm pretty certain I have one waiting for me there. Bob . . .

One is 15 ft. and one is 24 ft. Yeah. I seem to recall a tid bit from the dark recesses of history that the longer cable was the 'golden' device and the shorter one had padding capacitors in the connector to make up the difference between the two. I don't think there were any off the shelf, low capacitance cables made as twisted pairs. Those would be comparatively huge bundles. When they went to an internal goniometer, the loop became less critical . . . impedance matching could be accomplished in the gonio-transformer. Do you intend to fly this radio? What's the expected distance from radio to loop? If it's relatively short, say on the order of 6-10 feet, I think I'd try plain vanilla shielded pairs and see what happens. I don't know if I ever knew . . . is this radio among the ranks of those where the long-wire sense antenna was eliminated? Given the wide frequency coverage (250-1700 KHz) 1:7 ratio, it seem unlikely that antenna features and feedlines will be in any way resonant. It seems more likely that special attention be paid to ratiometric values of impedance and phase. So I'm guessing that the feedlines for this radio need only be identical as opposed to trimmed for resonance. Bob . . .

    Hi Bob, Mainly I just want to learn more about ADF. I also have a 1946 Stinson (besides the RV-7A) that I may install it in once its working just to see what ADF navigation is like, but that is some time away. Yes, I'll try some plain vanilla cable to start with. I think that 6 to 10 ft. would work in the Stinson. Two ft. would work on the bench here. If one knew the value of the padding capacitor and the length of cable it replaced, that would answer the question, wouldn't it? There is a bench setup in the service manual that mentions a cable (pn 200-0440-00) with capacitance of 144 pF. (I found this after sending the email below.) It also shows a sense cable (pn 200-0447-00) with the same capacitance. The loop cable part number is not the same as in the installation manual, though!! There is mention of a King Service Memo -- SM75 -- in The Technicians Notebook by Jerry Gordon. www.aerostandard.com/images/TecnNote.pdf He says, "Its a long drawn out procedure to determine the proper ADF sense antenna configuration. What it boils down to is you need a capacitance meter in your shop." I know we're talking about loop antennas here, but I'd be interested to see SM75 if you have access to it. I can scan the test setup page and the receiver front end. I don't think attachments will work on this list. How do I share the scans. I can send them as .pdf files.

    Bob, I forgot to answer this question. Bob asked: I don't know if I ever knew . . . is this radio among the ranks of those where the long-wire sense antenna was eliminated? Yes, sort of, but not in my case: The loop antenna I have -- KA42 -- requires a separate "50 pF" sense antenna. I see in the install manual that the radio is designed for 194 pF sense antenna system -- 144 pF cable plus 50 pF antenna. It also refers to Field Service Memo #75 which I would like to find. The loop antenna KA42B has a built in sense antenna. It requires a matching assembly (pn 200-02104-0000). The schematic for this assembly is shown in the install manual. It feeds 8V to the antenna unit and uses 50 ohm coax -- length not critical. Apparently there is an amplifier in the antenna unit. Dan

    Subject: Garmin 340A Acting Up
    I was out flying on Saturday and all of a sudden my Garmin 340A audio panel lit up like a Christmas tree. All of the lights came on at once. I pressed Com1 and Com3 buttons a few times and then everything went black. Then I remembered that old adage about gas in the truck, sky above you and your spare radio back in the car :) Since it was snowing I turned back to the field and on the way back turned switches on/off, pushed buttons to no avail and so on. Back at the shop I checked the fuses (all good), re-seated the connections, turned the ship's power on/off, cursed at it and so on. All efforts were in vain. I then turned the ships power back on, turned the power switch on and pressed the "Test" button. With that all the marker lights went on. Releasing the test button extinguished the lights and all was again dark. Any thoughts? Has anyone seen this behavior before? Up until Saturday the unit worked without issue. Glenn

    Subject: Re: Red Dot Digital SWR Meter
    The "Red Dot" SWR meter was waiting for me at the Post Office this morning. I don't have a lot of sources for significant power generation at VHF but here's what I found. When compared with some Bird wattmeters, the Red Dot readings were in agreement to within 10% or better at 130 MHz (1W hand held) and 146 Mhz (5, 10 and 50W transceiver). The Red Dot pronounced one of my loads as presenting a 1.2:1 SWR and the forward 9W, reverse 0.08W readings were consistent with calculations to produce 1.2:1 SWR. Even with the 1W hand held, it was in direct agreement with the Bird equipment at 0.9 watts out. When you power it up, it cycles between forward power, reverse power and SWR. You can hit the button to hold it in one of these three readings if you're making adjustments. Inside appearance is good. It even has multi-turn trim pots and itty-bitty variable capacitors no doubt useful for calibration (or re-calibration in the future). The interior inspection revealed the time honored pair of directional couplers and their associated load/detector components. The real value for this little guy probably lies with the microprocessor driven display. I have every reason to believe that the designers use a processor not only for a/d and display driver, I suspect their calculations take low power detector non-linearities into account as well. A 1W power level does not produce 1% of the DC output as a 100W power level. From what I've seen today, this instrument appears to be a good value and MUCH more suited to VHF measurement than most of the commercial-off-the-shelf CB/HAM meters in circulation. If you're contemplating acquisition of this product, don't forget to order BNC-F to N-Male adapters. You'll also want to fabricate a piece of coax about 2' long with BNC connectors on each end to let you insert the instrument into your ship's transmission line. Bob . . .

How about adding a garage-door opener type radio remoted to operate the hangar door and changing your exposed switch to some kind of key-operated so that you can still have wired access if the batteries run down in your remote?

    Subject: Re: Garmin 340A Acting Up
    Unless Garmin has changed their customer support attitude, I suggest giving them a call and get a senior panel avionics tech guy on the phone. They will work with you. And, it could turn out that they fix it for n/c.....

    Subject: com antenna mounted
    From: "messydeer" <messydeer@yahoo.com>
    Hi! Thought I'd post a followup from a few months ago when I was making my com antenna. See http://forums.matronics.com/viewtopic.php?t=85809 In short, it's a RadioShack CB antenna that I cut short. This allowed me to screw in the threaded post into the female-female coupler, which I threaded onto the UHF antenna connector I got off ebay, which is also shown in the original post. It came with a white plastic shoulder washer that insulates the antenna from the airframe. So far all this is on the outside. On the inside is the other end of the UHF connector and a UHF to BNC adapter on top of it (my antenna is belly mounted). I gave Bob the length needed for my antenna cable and he made up an assembly with 90 BNC connectors on each end. This is a really great deal, since I don't have crimping tools for this. It was time to install it permanently today, so I took a couple pics and have posted them below. You can also see a small 063 doubler I added. And in the outside pic, the shoulder harness is dangling below the floor, making for a little confusing pic. -------- Dan Read this topic online here: http://forums.matronics.com/viewtopic.php?p=366007#366007 Attachments: http://forums.matronics.com//files/com_antenna_outside_2_419.jpg http://forums.matronics.com//files/com_antenna_inside_126.jpg
