[Elecraft] Sudden K3 AGC pop-off after adding P3
All, After building and installing a new P3 pan adapter on a relatively new K3, I notice the AGC fast or slow setting would suddenly shut off, accompanied by a loud, distorted blast of signal audio. Normal AGC function is re-established by holding the AGC button, then tapping to select fast or slow. That would happen after a random period of time after power up and sitting on a frequency, (several minutes to an hour). I did not notice this issue before the P3 was plugged into the rig. I¹ve run the K3 over a week, including through the CQP contest and never noticed this issue before. Not sure if this is a software glitch or what. With a Heil Pro Set on, it is painful since it is unexpected, resulting in my rapidly and forcibly removing the Heil Pro Set from my head! At the time, the P3 was also connected to a PC running HRD v5.0. No specific commands issued to HRD at the times of the AGC pop-off. I was not transmitting at the time it occurred either, (RF not an issue). I have the P3 right up against the right side of the K3 with only a few mm separation afforded by the rubber feet on the K3. I notice the K3 case is hotter there, as the voltage regulators are attached internally to the case. Should I allow some space for cooling there? Any ideas? 73, Dan Sherwood WA6PZK __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Sudden K3 AGC pop-off after adding P3
Dan, This is a known issue with HRD used with the K3. It happens with me a few times a week with my K3+P3. Reducing the polling rate of the K3 in HRD may reduce the frequency of this issue, but it won't eliminate it. The choice seems to be either put up it, or stop using HRD. Simon Brown has handed over the reins of HRD development, so perhaps the new team can devote some time to investigating and fixing this. vy 73 de David M0DHO __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] (Parts) containers
Hi, all concerned: Fwiw, SUNMAID dried fruit products are marketed in 16oz paper containers, and various brands of meat and tuna products, in 12oz tins. The SUNMAID plastic lid fits the tin tightly enough that a 1M drop doesn't dislodge it, sending parts to the winds. They stack nicely, the factory labels peel right off, and they can be re-labeled with masking tape and a SHARPIE marker.

Dan, As David indicated, this is caused by HRD.

[Elecraft] K3 RF in SSB audio on 6M
Only on 6M when I operate above 250W, I have RF getting into my SSB audio, using either the the R or F mic connector but slightly worse with the R mic connector.

Re: [Elecraft] K3 RF in SSB audio on 6M
It is difficult to impossible to cure RF-in-the-shack at the transceiver end. The most certain solution is to work on the antenna system. Baluns at the antenna feedpoint and RF Chokes at the point where the feedline enters the shack are the most effective. In other words, keep the RF inside the feedline where it belongs and prevent it from getting onto the outside of the coax. For those with attic antennas (or otherwise quite close to the shack), the situation is difficult to cure because you can have direct radiation from the antenna in the shack, and the only cure I know for that is to reduce the power. 73, Don W3FPR On 10/8/2011 8:26 AM, Howard Sherer wrote: Only on 6M when I operate above 250W, I have RF getting into my SSB audio, using either the the R or F mic connector but slightly worse with the R mic connector.

At the time, the P3 was also connected to a PC running HRD v5.0. No specific commands issued to HRD at the times of the AGC pop-off. I was not transmitting at the time it occurred either, (RF not an issue). As indicated by others, this is an issue with overpolling by HRD. HRD enables the *K2* extended response mode and then polls for AGC status *three times in succession* with no lag between the response to one poll and the next poll regardless of the Refresh Interval set in the HRD Options. It appears that the slight delay in data through the P3 and the poor programming in HRD combine, perhaps with noise, to generate a false AGC OFF command. One known work around (although with side effects of its own) is to use LP-Bridge as a buffer between HRD and the K3. LP-Bridge answers many of HRDs polls from its own cache and reduces the excessive of the K3/P3. Note - GT; is not the only duplicated poll issued by HRD. In addition to polling for AGC three times, HRD polls for both VFOs (FA;/FB;) twice, selected transmit VFO (FT;) twice, Bandwidth (FW;) *five* times, Antenna selection (AN;) twice, and Power level (PC;) twice! 73, ...

Too short IMHO. I think it is 3ft or 1 Meter. 6ft or 2 meters would be better or at least an option for 6ft. Mike W0MU I agree. The 3-foot AUX cable doesn't work for me.

Re: [Elecraft] Send a simple tone
Sometimes I just have a brain mailfunction. All the answers made me realize that I needed to plug a switch in the back of the unit not in the front via my mic cable. Once this was sorted out and the radio in CW and VOX on I could do what I wanted to do. I was aware of the tune function but I was slow at it and for the test I wanted to do, I wanted the ability to do short bursts and adjust the power while in key down. But I do learn. I even worked I32C in split mode the other day, and I am sure you guys remember my brain block questions back then. Thanks again for being a fun and understanding group.

Re: [Elecraft] Bad KIO3 board
If all you are using the serial connection for is PTT you can add a transistor and resistor to the RTS line of the computer serial port or USB converter and connect it to the PTT jack on the K3 rear panel. Otherwise, you can simply turn on the K3's VOX in DATA Mode and use any sound card. The Signalink USB will not provide radio control (CAT) as it simply generates a PTT signal when its sound card is making noise. 73, ...

Re: [Elecraft] Sudden K3 AGC pop-off after adding P3
Joe, That's certainly a plausible explanation. We ran MM logger all last weekend during the CQP without problems, (P3 not built yet). I had no issue with HRD earlier yesterday, until later at night when I switched to 40 and 80 meters looking for few signals through heavy static crashes. With all the AGC pumping going on is when I had these problems. Have the K3/P3 running all morning w/o HRD. No problems. I'm looking at the LP bridge website now.

Re: [Elecraft] Sudden K3 AGC pop-off after adding P3
The real deal would be why the over-polling is necessary in the first place. I'd guess it's done to service ALL the different rig types (not just Elecraft and K3) with a single strip of code, instead of pushing those constants at program startup based on the target or configured hardware. If it's not cheep code, then it's certainly not state of the art, nor at all close. One always should have a constants library which carries the array of values necessary to drive any hardware timing sensitive code. Where I worked at my last TWO places of employment, going back to an ATT school in 1976 (!), embedding target-variable constants in program code and using code switches would get your code summarily rejected by a reviewer or auditor, subject one to an auditor approved redesign and recode (with prior effort flushed down the turlet), and have an effect on one's pay grade. There was a brutal standards are just that attitude. Putting in the table driven code costs some in the beginning, but saves huge in maintenance, and a maze of switches eventually means recoding in its entirety. That's probably what we're really fighting with the HRD code. Otherwise it's a simple table change that gets done in seconds, and then recompiled. 73, Guy.

Re: [Elecraft] KAT100 Problem
Larry, I would suggest that lightning, wind or rain static has damaged the wattmeter diodes in the KAT100 so it can no longer properly measure either power or SWR. Those are the 1N5711 diodes at D1 and D2. You might also check diodes D16 and D17 in the KPA100 while you are at it - it is rare that the KAT100 diodes are damaged when the KPA100 diodes escape damage. 73, Don W3FPR On 10/8/2011 2:35 PM, Wolfgang, Larry, WR1B wrote: While trying to make a few contacts in the PA QSO party, I hit the Tune button to adjust the match to my antenna.

Re: [Elecraft] Sudden K3 AGC pop-off after adding P3

Re: [Elecraft] K3+P3+HRD AGC Problems
David, I followed Joe¹s idea of using LP-Bridge. I noticed the update rate is somewhat ³hurky-jerky², but the AGC pop-off has not occurred yet. This combination of software is also not indefinitely stable over time, with HRD requiring restart periodically to get ready of the ³DATA² error in HRD¹s rig display. I¹d pay good money to someone who makes HRD work properly as I really like the interface for casual DX logging. Thanks for the input. 73, Dan WA6PZK On 10/8/11 9:56 AM, David Inger ingerassocia...@verizon.net wrote: Hi Dan, I see you have received several responses to your question. I raised this same issue several weeks ago, and also received responses pointing to HRD. I have noticed that HRD and the K3 play well together, until the P3 is added; then the AGC problem shows up. After having used HRD for many years (on many radios), I think I am going to have to abandon it, unless the new owners of HRD can fix the problem. This is too bad because I really like the DM780 digital module; no other digital package runs so many different programs. The only other option is disconnect the P3, and I¹m not going to do that. The DX Labs suite or TRX-Manager may be an option, but I will still try to run DM780 as a standalone.

Re: [Elecraft] Sudden K3 AGC pop-off after adding P3
Why should polling the AGC randomly turn it off on the K3? Because HRD uses the *K22* mode. If HRD would use the K3 commands and not enable the K2 extended command set, the GT command would require an explicit off command. What appears to happen is a data clash between HRD and the P3 ... P3 data or an echo gets appended to the the GT; poll to the K3. The the corrupted data is just right AGC is turned off. Why does HRD use an old command set and why does it poll for AGC status *THREE TIMES*? Polling for the same data three times in 31 milliseconds is stupid, sloppy, and increases the chance of false triggering exponentially. 73, ...

Re: [Elecraft] K3 RF in SSB audio on 6M
On 10/8/2011 5:26 AM, Howard Sherer wrote: I have installed Fer chokes on the audio input lines with no improvement. Any suggestions. What sort of ferrite choke(s) have you installed? A single turn through a #43 or #31 ferrite core puts the resonant peak in the 150 MHz range, while a single turn through #61 puts it in the 500-800 MHz range. If you want a choke to be effective at 50 MHz, you must wind at least two turns through the core, and you will likely need multiple two-turn chokes in series on whatever cable is picking up the RF. While I completely agree with Don that it's critical to keep RF off the coax, a 6M antenna that is close to the shack could easily radiate enough signal to excite a Pin One problem, and you won't solve it by choking the coax, you must choke whatever outboard cables are receiving the RF. Also, VERY important -- the nature of Pin One problems is that it is not ONLY audio cables that can have the problem. ANY cable whose shield (or common) goes to the circuit board rather than to the chassis can be a Pin One problem, including key lines, PTT lines, headphone lines, speaker lines, serial cables, and the AUX cable. A completely different mechanism that SOUNDS like RFI is NOT RFI at all. That mechanism is modulation of the V- line from the power supply by the IR drop that results from modulation of the DC that powers the radio. That modulation can be as much as a volt, depending on the current, the line length, and the wire size. If some piece of unbalanced audio equipment that feeds the transmitter is powered from the power supply end of the cable, and if V- is bonded to the chassis in the power supply, that modulation will appear in the unbalanced signal return, and will be added to the audio. It SOUNDS very much like SSB audio detected by an AM detector. Why might it appear on 6M and not on other bands? It might if that the power supply is also feeding a 6M brick amp, or if whatever outboard gear is powered from the power supply end of the cable. If you have NO outboard boxes connected, then it's almost certainly an RFI problem, and almost certainly a Pin One problem (which means it can be killed with the right choke(s) in the cable(s) that are acting as the RX antennas. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Strange Sub Receiver Problem - I must be on Ant 2 in order to receive
Yes, you have your subreceiver wired to receive on the alternate jack on the KAT3. This means that a HOLD on RX ANT will flip back and forth between the sub RX listening on the TX antenna or on the NON-TX antenna jack. Do a hold on RX ANT and you will see either MAIN or AUX. MAIN is the CURRENT transmit antenna. AUX is the OTHER antenna. 73, Guy.

[Elecraft] Elecraft CW Net Announcement
Good Evening, Since last weekend there has not been a day over 53 degrees. Next week even those warm temperatures will be gone. Night time temperatures are just barely in the 40s. Rain and heavy fog almost every single day keeps the sun from warming anything. We went from a very cool and wet spring to a few weeks of dry weather and then instantly into winter. Skipping seasons is not unusual here but skipping two of them in one year is very odd. Well a few weeks break in the heating season was something :) Propagation has been very good. Reports I've read and time on the air just listening show me bands from ten down to forty meters are open. Forty meters is as low as this excuse for an antenna will go since it is just a run of coax to a balun draped in a tree where it fell. But it does allow me to listen around a bit while working on these computers. Ten and fifteen meters have been bringing in some exotic call signs. It is fun. Listening to the high speed code on W1AW is also a fun test.
