[Elecraft] K2 RFC15 question
Anyone familiar with the mod for VFO stability around 7.182 MHz? It involved a tiny 100uH choke and a 68pF capacitor. Well, I broke the choke and replaced it with a toroid I had laying around that was 10uH. I'm wondering if I should get the original choke or just leave things the way I have them.

[Elecraft] sensitivity/noise question
Compared to my IC-706MKII, the Elecraft seems to be stingier on the S-meter and seems to hear a lot less noise. And yes, I used an antenna switch and did A/B comparisons. I shouldn't complain, since the Elecraft is great to listen to, especially on 40M, but should I break out the test equipment and try to peak things up again? And now that I type this, I wonder if my cabling is OK. -- Hisashi T Fujinaka - [EMAIL PROTECTED] BSEE(6/86) + BSChem(3/95) + BAEnglish(8/95) + MSCS(8/03) + $2.50 = latte ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] KPA100 voltage measurements?
Tom, I have not yet seen a reply on the reflector to your questions, so I will try to give you some information. The voltage at U5 pin 1 will depend on the reflected voltage sensed by D17 and the setting of R27 - if you are measuring the voltage under transmit conditions, do you have a good dummy load connected? Pickup on an antenna wire connected to the output MIGHT do strange things during receive periods too. You should have the same voltage on U5 pin 1 and pin 3 because U5A is a unity gain op amp. If the voltage on pin 1 is much different than the voltage on pin 3 the problem will be found after the op amp U5A, but if they are the same, the problem is in the SWR bridge or its adjustments. I am at a loss to explain 28 volts on U6 pin 6 - that is another op amp and it is powered from a 5 volt supply, so the pin 6 voltage will never be brought higher than 5 volts by anything in U6 itself. A regular RS232 computer cable plugged into the KPA100 and connected to a computer might cause that kind of voltage - DO NOT USE A REGULAR COMPUTER SERIAL CABLE - BAD THINGS WILL HAPPEN. Check for something tied into the VRFDET line somewhere in the base K2 or on the KPA100 board's AUX IO umbilical cord and/or the DB-9 connector. Follow the PC board traces from U6 pin 6 to the connection with the cable and the DB-9 connector for a short to an adjacent trace or solder pad. That is all I can tell you with the info I have right now. 73, Don W3FPR - Original Message - > > Am on page 23; KPA100 test points and have two problems: > > U5 Pin 1 should be 0 to 0.1; I get 2.4 > > U6 Pin6 should be 0 to 0.5; I get 28v! > > Any ideas or where to look?

And if, how? I don't believe in "off-list" replies except for buying/selling stuff. I have done a fair amount of work on this, and can give you some very simple methods using the MFJ-259B or the AEA CIA-HF. So here goes. The equivalent circuit of a choke formed by passing a wire through a bead is simply a series R and L (or R and X L). Both R and L vary widely with frequency. That is, there is not a single L value, nor is there a single X value that describes the choke at all frequencies. Rather, there is a set of curves that describes both R and X. In general, R and X both start off small at low frequencies, both increase with increasing frequency, and at some frequency X (or L) will drop off to a pretty small value leaving only R. To measure these curves for any ferrite, simply take a short piece of wire, pass it through the ferrite, and connect the wire to the analyzer. Then read the impedance over a range of frequencies, put the values of R and X in a spreadsheet, and compare them to the datasheet for the material. There are excellent data for Fair- Rite beads in the Fair-Rite pdf catalog on their website. I strongly recommend this catalog -- in addition to the data, there are some excellent applications notes that talk about how ferrites work and how to use them. You can also wind multi-turn coils through many ferrites (depending on their size and shape). This will increase the impedance (both R and X) at any frequency, but will also shift the peak in both R and X to a much lower frequency that is sort of proportional to the square of the number of turns. For example, the #43 mix peaks somewhere around 100 MHz for a single turn, but 8-10 turns will pull the peak down around 80 meters, and 14 turns or so will get it down in the AM broadcast band (you can easily do this with the 2.4" OD toroids commonly used for baluns. The limit of measurement for the MFJ-259B is 650 ohms, and for the CIA-HF is 1K ohms. Many multi-turn chokes will result in impedances well above this.

[Elecraft] OT - Testing Ferrite Beads using common tools
Hi folks: This a pretty off topic, but I hope someone might be able to shed some light upon this question. A couple years ago, at the Dayton HamVention, in a fit of greed, I purchased a number of ferrite beads which, although they were NOT the FB- 73-2401 beads I usually buy, they WERE "advertised" (by the seller) as being mix 73. These beads have a somewhat larger inside diameter, making it easier to slip them over slightly larger diameter coax (e.g. RG-8X, etc.). And the price was REALLY GOOD (hence the previous reference to 'greed'). I am now at the point of wanting to use these beads, but I'd like to confirm that they might work at HF. I don't have a lot of sophisticated test equipment, BUT I do have a sign gen, 100 MHz scope, an MFJ-259B Antenna SWR Analyzer, and the more commonly available 'shack-type' tools at my discretion. Does anyone happen to know of a way to do some cursory testing on these beads (possibly using the MFJ-259) to tell if they might offer a decent impedance at HF? And if, how? Since some of our OT threads seem to linger MUCH longer than they should, please reply to me OFF-REFLECTOR and if I can confirm that a particular procedure works as advertised, and it repeatable, I'll summarize it (giving full credit to whomever offered it), and post it back to the reflector. 73, Tom N0SS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Certainly can't afford the price of an IC-7800 - E or otherwise!! ;) However I did have a chance to see 4 of them in play at our Field Day site and operated one myself for a bit. My net impression is an agreement with the stuff between the [snip]s. We were 4A with a GOTA station - perhaps 80 feet between each of the three towers and a little more than that to the GOTO Windom. The only problem experienced was some RF interference with the headsets. Pull the plug of the headset and the interference was not heard in the speaker. This is running CW/SSB on the same bands with no auxiliary filtering. It was a radio that was very easy on the ears and very easy to use radio. Would I buy one if I had that kind of discretionary cash - oh, probably! But I would still keep my K2 QRP and add a KP2/100 as well. But I don't so I will just save some money for a K2/100.
