[Elecraft] ARRL Modified Regulations by Bandwidth Proposal
Hi All, In the September QST, there is an article that relates that the ARRL Board of Directors has approved the subject plan. Details of the plan are at http://www.arrl.org/announce/bandwidth.html As a QRP CW and PSK31 operator I have a lot of problems with this plan. The lowest frequency division, 200 Hz allows CW and low bandwidth digital operation like PSK31/63 and 60 baud RTTY. For example, on 40 meters, it runs from the lower band edge up to 7035 Hz. As the lower 25 Hz of the US allocation is reserved for Amateur Extra, other CW and narrow bandwidth digital operations are squeezed into 10 Khz and the US QRP calling frequency of 7040 is excluded. Other bands are somewhat similar. The next division by frequency is 500 Hz which permits all wideband digital operation except Pactor III. Granted, the lower bandwidth stations can operate in the higher bandwidth portions, but the division is heavily weighted toward mailbox stations using Pactor II. The effect of this allocation are that semi-automatic mailbox stations using unattended Robot stations will continue to run roughshod over the PSK segments. As the PSK segments are established by International Gentlemen's agreements, this proposal is of interest to the International community as well. I have commented to my ARRL director, and am prepared to also comment to the FCC when the proposal is submitted. The site http://mywebpages.comcast.net/hteller/changes.htm contains some recommendations for changes to the bandwidth proposal and suggestions on what to do.

RE: [Elecraft] KIO2 not working
James, All those voltages look OK to me. The voltage on pin 11 is dependent on the state of the signal at pin 6. If you wish to test it, pull pin 6 to a negative level (jumper from pin 8 to 6) and you should see pin 11 go to 5 volts - a positive voltage on pin 6 should produce a 0 volt signal on pin 11. The reason you see zero volts there now is that the chip is interpreting the floating state of RXD at pin 6 as a positive voltage - all that is OK because voltages between -3 and +3 volts on the RS-232 signals are in a region of uncertainty. Your problem likely lies with an unsoldered connection somewhere or a broken inductor - check the miniature inductors for continuity. You had previously reported 0 volts on pin 2 of the 9 pin connector, but you have -9.85 volts on pin 5 of U1 - the only series element between those points is an inductor and it is likely the path is open if the voltages at the two points are substantially different. 73, Don W3FPR -Original Message- Alright, I followed the steps for No (-) supply at U1-8 and this is what I got: The oscillator was oscillating at 16.292 mhz I took the voltage readings of U1. Pin 1 = 12.32 Pin 2 = 0 Pin 3 = 11.80 Pin 4 = 0 Pin 5 = -9.85 Pin 6 = 0 Pin 7 = 11.79 Pin 8 = -9.85 Pin 9 = 0 Pin 10 = 0 Pin 11 = 0 (This is supposed to have 5?) Pin 12 = 5.06 Pin 13 = 4.8 Pin 14 = 0 Pin 15 = 4.81 Pin 16 = 4.81 The serial port is enabled in the menu. -- No virus found in this outgoing message. Checked by AVG Anti-Virus.

Posting from Antoni Navarro... I'm sad to communicate that Paulí Nuñez EA3BLQ passed away last July, 20th; being 76. As I knew he traduced the K2 manual to Spanish, and designed a digital signal transmiter board to be used with the K2 I wanted to make know that to the mailing list's people. Thank you.

Re: [Elecraft] KIO2 not working
I agree with Don's analysis. Everything looks good around the MAX1406 transceiver. Since you have -9 volts or so at the output (pin 5), and zero on the pin it feeds, there must be something amiss in between. The small inductors are easy to break - this might be the problem, as could be missing or 'bad' solder joints on either side of the inductor or at J1 pin 2 itself. Use a VOM or ZDVM to make sure that L2 has continuity (might as well check L3 and L4 at the same time), then recheck the solder joints. If the inductor is bad, I'm sure Scott will be happy to get you going with a good one...

[Elecraft] Panasonic Oxyride battery in KX1 report
I bought 8 Panasonic Oxyride AA's at Walgreenls for $10 and when my Energizer Lithiums gave out I switched them in. These new batteries are 1.7v and are marketed as lasting longer than traditional Alkaline. The results were not good. They measured 1.7v with my cheap backpack DVM, and the pack was about 10.3v, and I get 9.9v on my KX1 volt meter from 6 of them in the internal holder. Unfortunately, when I transmit on 20m, it goes down to 8.5v, with 2W out shown (ATU match 1.2:1). I will try cleaning the contacts, but for now it looks like they have a higher internal resistance than one might want. Also, I found that, under no load, only one of my expired Lithium batteries had a low voltage; the others did not. I know Li primary cells have a steady voltage throughout the discharge curve, but it may be that I can get some more life out of the rest somehow.

[Elecraft] Solar Panel Controllers
Hi I have kitted up another batch of my Solar Controller Kits. The kit comes with all parts and a fiberglass silk screened and solder masked circuit board. This controller is designed to work with a 12 volt sealed lead acid or flooded lead acid battery. The battery can be any capacity from a couple of amp hours to over 100 amp hours. One or more solar panels from 3 watts to 200 watts can be used with this controller. This is an analog design so it does not generate any RF as some switching regulators. The circuit board is 2x3 inches and can be built into the radio or battery box. It uses a precision regulator so there are no adjustments required. The price for the kit is $30 check or money order.

[Elecraft] Leather Case for K2
Hello everyone. I have made an inquiry to have a leather case made for my K2. I was thinking of the type used for binoculars with a shoulder strap. This way the rig can be taken out and put back. Plain leather without fancy adornments though. Or one that fits snuggly around the K2 like a glove. No need to have the rig remove, just open the front/rear flap. I have about four leather craftsman waiting for info/design. This is just a exploratory note to see if any one else might be interested. Details of cost/design etc will be later. Perhaps the cost might be prohibited, I don't know. Any one on the list gone down this path? Comments to my email would be fine so that we don't clutter the list. -- 73 Fernando N2FQ/NNNØJYM San Jose, CA http://pages.sbcglobal.net/n2fq ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Even the QRP K2 has a heat sink on the bottom that needs a little air space if you're working in a warm location and doing very much transmitting. Maybe a stiff floor in the case on which the K2 feet rest so when the front and back are open there's a gap between the feet under the unit.

RE: [Elecraft] Ok, K2 progresses but now no audio.
Jess, Where and how you start depends on what test equipment you have available. To begin, we need to know whether the problem is in the audio stages or in the remainder of the receiver. Do you have a 'scope available? How about an audio signal generator? Do you have a computer with a sound card that can be used as an audio source? Do you have an audio amplifier available with a phono or mic input available? You can connect an audio amplifier input to the RF board J5 location (pin 2 is ground and pins 1 and 3 are the outputs from the product detector. If you can hear anything through the external audio amp with that setup, the receiver is working up through the product detector. Injecting an audio signal into RF Board J5 pin 1 or pin 3 (ground connection to pin 2 should produce an amplified audio signal in the headphones if the audio stages are working. You can use a computer sound card (line out or speaker out) as the audio source - play a CD on the computer and listen for any output from the K2 headphones (first make certain you can hear the computer audio through the normal computer speakers to verify that the setup is correct). The fact that you have sidetone only shows that the final audio amplifier IC is capable of output, the sidetone signal is injected into that IC separate from the receiver audio path. What I am really saying is that we need to know which half of the receiver is at fault here - audio stages or RF/IF, product detector stages. 73, Don W3FPR -Original Message- I am testing the 40 meter receive and peaking filters at stage II testing.

RE: [Elecraft] finding caps
You would do well to review something like the ARRL Handbook 'Component Data' section to become familiar with the various markings used for capacitors. The cap marked 820 should be 82 pf, the disc ceramic marked 4.7 is 4.7pf, the cap marked 181 is 180 pf and the one marked 182 is 1800 pf. A 47 pf capacitor will likely be marked 470 or in exceptional cases marked 47. The key is that a capacitor marked with 3 digits follows the '2 significant digits plus multiplier' rule (the first two digits give the first two digits of the value and the multiplier tells how many zeros to add to those two digits) - values marked with only 2 digits are generally the actual value. PS - ignore colors and other manufacturers markings - those things can change as fast as parts suppliers manufacturing lines - I can tell you the colors of tha capacitors shipped with the last K2 I built, but those colors may have changed with the next one off the kitting line. 73, Don W3FPR -Original Message- on page 51 locating the following capicators c71 (82) and c73 (47) there is a 820 and an 4.7and c 182 (181) there is a 182 -- No virus found in this outgoing message.

Plain leather without fancy adornments though. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Ok, K2 progresses but now no audio.
Jess, Make sure you have the jumpers installed in place of R18 R19 on the bottom of the control board. These jumpers provide the path for the output of the product detector U11 on the RF board. If no go, check the RF board jumpers W1, W6, W5, W2 and W3 to make sure the RF is getting to the receiver preamp, mixer, the variable bandwidth crystal filter and then to the IF Amp and Product detector. From the product detector, PD1 and PD2 go through RF board J7 to P2 on the control board. On the control board, you've got Q6 and Q7 which disconnect the AF amp when transmitting.

I got the problem with the PLL licked and everything was working as advertised. Now I cannot get any audio out of the radio. No hum, no hiss, nothing with an antenna connected. I do get side tone and spot tone, so that tells that the audio amp is working. Where should I start?

[Elecraft] K2 tinny speaker
Finished the KPA100 and installed it in the K2 and I must say I'm disappointed with the audio quality. It sounds like I'm overdriving the speaker but the volume isn't near what it was with the original speaker. Is this normal for the K2? If not, any suggestions on how to make it sound better?

RE: [Elecraft] K2 tinny speaker
Craig, Certainly - just in case the speaker frame is bent, take the speaker from the QRP top cover and mount it in the KPA100 - it should sound the same - the only difference is the wires, and wires do not add distortion. OTOH, you are judging the sound quality with the KPA100 fully in place on the K2, are you not? If you are making judgements with the KPA100 laying on the bench beside the K2, be aware that the enclosure provided by the K2/100 adds a LOT to the quality of the speaker sound - the base K2 speaker sounds a bit ' tinny' when the cover is removed from the K2. 73, Don W3FPR -Original Message- Finished the KPA100 and installed it in the K2 and I must say I'm disappointed with the audio quality.

Re: [Elecraft] Leather Case for K2
You can find many suitable cases at places selling to other markets than ham radio. One time, I realized a lot of QRP rigs fit the insulated coolers for six packs. Makes a good way to store your rig in a car full time. Larger cases with room for air to circulate would work for operational field cases. Check out old camera gadget bags with hard sides at used camera stores or pawn shops. Stuart K5KVH
RE: [Elecraft] Panasonic Oxyride battery in KX1 report
Last night I was in Lowe's for one of my interminable shopping trips to keep my house upright, and they had the L91's $9.89 for a 4-pack, regular price. It's getting where an external 10-pack of L91s is getting affordable. Eric KE6US www.ke6us.com -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Leigh L Klotz, Jr. Sent: Wednesday, August 17, 2005 1:53 PM To: elecraft@mailman.qth.net Subject: [Elecraft] Panasonic Oxyride battery in KX1 report I bought 8 Panasonic Oxyride AA's at Walgreenls for $10 and when my Energizer Lithiums gave out I switched them in. These new batteries are 1.7v and are marketed as lasting longer than traditional Alkaline. The results were not good. They measured 1.7v with my cheap backpack DVM, and the pack was about 10.3v, and I get 9.9v on my KX1 volt meter from 6 of them in the internal holder. Unfortunately, when I transmit on 20m, it goes down to 8.5v, with 2W out shown (ATU match 1.2:1). I will try cleaning the contacts, but for now it looks like they have a higher internal resistance than one might want. Also, I found that, under no load, only one of my expired Lithium batteries had a low voltage; the others did not. I know Li primary cells have a steady voltage throughout the discharge curve, but it may be that I can get some more life out of the rest somehow.
