[Elecraft] K3/O-Mini + Remote Rig Configuration for Heil Headset
I am having difficulties getting my Heil ProSet with the HC-4/HC-5 mic cartridge to work with the K3/O-Mini + RemoteRig (purchased from Elecraft) where there is no audio reaching the K3 at the radio site. I’m told that the Heil mic cartridge is a dynamic element with no pre-amp gain. The mic connection for the K3 is set for the rear panel with no Bias and “Low” Gain per the Heil documentation on their website (“All Things Elecraft”). The incoming audio (transmit) is fed from the Remote Rig-Remote front panel Aux/Mic using the supplied cable from Elecraft that connects to both the PTT In and Mic-Mono at the back of the K3. I’ve tried various configuration setups with the Control-RR to see if changing the audio level from the control site makes a difference, such as increasing the Codec inp gain, changing Codec Inp preamp to “no” and varying the Audio Quality specified at both remote rig units. Using TX-Test, I then speak into the Mic and check for ALC and compression, varying the mic gain and compression. At no time do I see any measurement on the K3/O-Mini meters for ALC and compression. The “monitor” capability is also not working as I can’t hear myself through the headset. I’m wondering if the Remote Rig system is setup for the Elecraft MH-2 mic which I understand does have amplification. If so, this may prevent a dynamic mic cartridge working properly with Remote Rig-Control. I’ve tried using the mic input on the side of the K3/O-mini as well as using the Kenwood adapter to utilize the 8-pin connector. I saw a note the other day from Mark, VA2MM which shows his setup for the Radio Side and Control Side; those settings didn’t work. I’ve tried the default settings specified in the “K3-Remote Owner’s Manual” with no success. I have excellent audio quality coming from the K3 to the K3/O-Mini unit; the receiver audio sounds fine at the control site. I presume this means that there is a good audio connection between the two remote rigs. The radio site uses DSL with a low bandwidth (10 Mpbs Down/784 Kpbs Up) so if the receiver audio is good, I’m presuming that bandwidth wouldn’t be the problem on the transmit side as it would be on the higher capacity downlink to the DSL site. Any suggestions on what to check either in the K3 configuration or the Remote Rig setup at either the control site or the remote site? Given that the connection is through the internet, are there any router or other considerations that I should check? At the Remote (radio) site, I’m using the default UDP/TCP configurations for RRIG_cmd, RRIG_audio, and RRIG_sip with port forwarding to the Remote Rig-Radio. I do have the ability to access the Remote Rig-Remote from the control site so that I can make configuration changes at both ends and restart both Remote Rig devices. Consequently, I can update both Remote Rig boxes (control and remote) as needed. I should also note that the last time I was at the remote site, I was able to test the system at the station itself and push audio from the K3/O-Mini to the K3 via the Local Area Network when the K3/O-mini was next to the K3 on the same LAN. When I got back to the “control site” , I had no transmit audio at al to the K3.. That may suggest an internet issue, but at this point I have no real handle on the source of the problem.

Re: [Elecraft] KPA1000
I wouldn't be holding my breath Dan. At one time, quite awhile ago, there were rumors of a KPA800 and/or KPA1500, and I believe one or more prototypes were built. A good friend, one of the Elecraft KPA500 engineers, mentioned that those prototypes fed a lot of the design into the 500, possibly why the 500 will run forever on RTTY at 500+ watts. I'm told the field testers were instructed to run them with all bars lit. There are a lot of good 1.0, 1.2, and 1.5 KW HF amps out there, this may be a market Elecraft has decided to pass up. I don't blame them. My KPA500 is solid as a rock. I had a 1200 W amp before, I ran it at 500 W for a year just to see if I could tell the difference, I couldn't, N6RK now has my old amp, I'm a happy ham. If I run the temp up to 70C, [that would be constant CQ's in a RTTY contest] the fans kick in, my wife says "they're noticeable." I'm about 3/4 deaf, I always operate with headphones, and I don't notice it. YMMV I've never had them come on high on CW or SSB. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 12/23/2014 7:15 PM, KG5EJU wrote: Very new to Elecraft, just own a W2, but looking long at the KPA500.

Re: [Elecraft] KPA1000
Dan, No truth whatsoever as far as I know. There were prototypes for an 800 watt and a 1500 watt amplifier shown many years ago, but those served as 'learning lessons' for the KPA500. The KPA500 will do 600 to 700 watts with ease, weighs only 26 pounds, and integrates with the K3 making the K3 appear to be a 500 watts transceiver. That is why it is the choice for many DXpeditions - light weight and a decent (and usable) power level. My personal opinion is that the 500 watt level was chosen because it better suits the worldwide market than a higher powered amplifier, and is only 3 db down from a 1000 watt amp - only half an s-unit on the receiving end. 73, Don W3FPR On 12/23/2014 10:15 PM, KG5EJU wrote: Very new to Elecraft, just own a W2, but looking long at the KPA500.

Re: [Elecraft] [K1] Error27 - Alignment and Test Part 1
Benny, I just finished my basic K1, Serial Nr 3342, with the first filter board (20m/15m). I'm amazed at how well it went. No missing parts. Every jack & plug fits with laser precision. All resistance & voltage measurements fell right on, or midrange between the manuals listed parameters. I'd go back and recheck everything. Also make sure the small mini switch (oper/cal) on the bottom of the RF board is in the "OPER" position. It makes a difference when checking the U8 pin 1 and pin 8 voltages. All alignment procedures went as stated in the manual. My VFO range is 80Khz and I ended up taking ONE turn off of coil L1 to get it down to 3.095Khz. Actual range is 84Khz. Using my SteppIR DB-18 ant my first contact was with a station in Spokane, WA on 20mtrs. Later my 2nd contact was with a station in New London, CT. An actual QSO with names, rigs, etc. Lasted 17 minutes. Power = 3W. Now to start the 2nd filter board (17/30 meters). Thank you Elecraft and Merry Christmas and a Happy New Year to All. -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Benjamin Schmid Sent: Tuesday, December 23, 2014 02:02 To: elecraft@mailman.qth.net Subject: [Elecraft] [K1] Error27 - Alignment and Test Part 1 Hi everybody, I'm currently in the middle of building my K1 #3343. Right until now everything went just fine and it's been fun to build. I'm at the point of the first power up and wanted to test the ATTN relay. The LED comes on but there ist no relay clicking. When hitting BAND I realized that band change wasn't possible and the TRX shows E27. The filter board is completely plugged in and seated correctly. Off to the manual then. Have you tried turning it off an on again: yes. No relay clicking on power up. Until then i thought that was normal. I checked the orientation of Fil-U1. Its positioned correct and completely in the socket, no bent pins etc.. I checked the voltages of Fil-U1 everything within the specified range. I checked some voltages at the MCU, not all yet, all within range or as specified in the manual. I read some older posts abt similar problems. I checked Fil-R1. It's the correct value and the solder joint seems good. I followed the hole path of the aux bus signal from Fil-U1 Pin13 up to the MCU. Resistance is just the 100ohm of Fil-R1. I redid some solder connections on the way even though they looked good, as well as all solders on all multi pin connectors. On the FP-Board FP-RFC1 is the correct value, solder joints looks ok. (It's not a resistor) Kept reading some older posts and checked the coil resistance of all relays, all about the same resistance (not sure about the actual value right now) , soldering and position of all relays ok. Right now i redid some voltage measurements. I found out that the voltage at FIL-U1-16 is somewhat unstable. The first time i measured it was well below 0.3V. This time it was around 0.6 Volts, a couple seconds later around 1.3 V while Pin 15 is at flat 0.0V as it was before. Not sure what's that supposed to tell me. Did I fry Z1 while soldering? Or is it U1 itself causing the trouble? Any ideas are much appreciated! Thanks in advance and happy holidays. 73 de DG5WJ - Benny P.S.

Re: [Elecraft] [K1] Error27 - Alignment and Test Part 1
Benny, The voltage at U1 pin 16 may be OK - that is one of the resonator pins and can be loaded by your DMM. That is what makes it read as unstable. For some reason, the K2 MCU is not communicating with the band board firmware. Check all the soldering again, and if that does not resolve itself, obtain a replacement filter board firmware IC *and* obtain a replacement resonator (Z1) just in case that one is defective. If you happen to have a spare 4 MHz resonator on hand, try replacing Z1 - that could possibly be the entire problem. You never know until you try it. 73, Don W3FPR On 12/23/2014 12:53 PM, Benjamin Schmid wrote: Hi Don, thanks for your help.

Re: [Elecraft] K3 13.8 VDC power
RV's all contain power supplies that are designed to use 120 volts from either generator or park power, to provide fifty-sixty-ish DC amperage to the 12 volt (13.8) rails and "house" batteries around the RV. RV's run a LOT of stuff on 13.8: fridge controls, Air Cond. controls, fans, furnace, lights, alarms, water pump, etc. The difference between these power supplies and an automotive changer, is that the RV supplies are designed to work with a deep cycle battery (often a pair of 6V T105's in series) floating on the 12 volt rail, and have the 14.4 v bulk charge, 13.6 v maintenance or "absorbtion" charge and 13.2 float settings logic built in. The power supplies are also designed to provide up to charger max current rating to the 12 volt rail once battery(s) are charged. Typical power supply size for a pair of T105's is 55 or 65 amps, which will nicely power a station with a pair of K3's plus a lot of 12v accessories. T105's are more commonly known as pro golf cart batteries, with six in series a typical battery array in a golf cart. The power supply has to match the house batteries' rated max sustained charge current. When "house" 12v draw plus battery charge current exceeds the rated current, the power supply voltage drops to limit the current at the rated amperage. This is what I have in my RV. Camping World prices for these units can be beaten on the internet. http://www.campingworld.com/shopping/item/wf-9800-series-converter-charger-55-amp/58324 My RV is a self-contained field day station that can put everything on the 12 volt rail.The generator or park power runs the microwave, the air conditioning and the aforementioned RV 12v supply. The T105 house batteries could easily handle a 2 x QRP entry for the 24 hours. Using this kind of power supply at home to run a battery float system is very easy, once the venting and safe location of batteries issue is settled. The batteries and power supply can be quite a distance from the shack if single aught copper is used to bus the current from battery to shack and distribution/fuse device. 73, Guy. > > __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] K3 13.8 VDC power
Hi to the group I have a K3 and a KX3 with PX3 and PA100. I always keep an up to date config file on my computer. If I get an out of sequence power off I always restore the config using the Elecraft utility. If I load new firmware I also restore the good config. If I go to field day I make sure there is a good config file for each operator. This allows each operator to have their favorite settings and when I get home I can eliminate any unwanted changes by reloading my known good config file. I use a battery for camping and field day but even there a connector can come unplugged and cause trouble to the config file. Troubles in the config file do not always show up right away as any memory spot can be damaged. The config file can be spoiled by a fat finger when changing setting in the rig menu. It can also be spoiled when having trouble reloading firmware. My recommendation is to keep the config file clean and ready. Battery backup may be used for other reasons such as finishing a QSO but it should not be used just to prevent config file problems.

Re: [Elecraft] K3 13.8 VDC power
I have noted that if you remove power it does not give the processor time to save the last frequency and other settings that it automatically saves (operating conditions).

Re: [Elecraft] K3 13.8 VDC power
Thanks Roger, that information is rewarding. Imagine what would happen if a power outage occurs during a firmware upload. The odds are slim, but my middle name is 'Murphy'. I want a good battery in my laptop as well. It has to finish the upload.

Re: [Elecraft] K3 13.8 VDC power
My setup is charging a 33 AH AGM battery via a West Mountain Radio PowerGate PG40S that feeds a distribution panel for the K3, P3 and other 12v accessories. The power supply input to the PowerGate is a PowerWerx SPS-30DM. The system can handle short power outages and keeps the battery correctly charged. I only turn the P/S on when using the rigs unless the PowerGate indicates a need for 'bulk' charging. When it goes to float, I turn the P/S off. I really see this as an uninterruptible P/S protection for the station. It was also helpful when I was chasing down an interference signal I was seeing by eliminating any source in the house (cut the AC mains and ran the K3/P3 form the battery.) 73 ..mike AI6II -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-13-8-VDC-power-tp7596240p7596302.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] K3 phone plug
I had that problem early on and figured it was a film of some kind on the innards of the jack - had to wiggle the plug to get it to work. So I used some of that high dollar contact cleaner on the plug and then while it was still dripping wet, plugged it in and twisted it around for a few seconds. That fixed the problem. Your mileage may vary!

Re: [Elecraft] [K1] Error27 - Alignment and Test Part 1
Benny, Error E27 says that your filter board is not being recognized. Turn the manual to the Troubleshooting Appendix in the rear , page 2 and do the checks indicated in the E27 block. Be certain all pins of the headers to the filter board are well soldered. If the band board firmware (U1) is plugged in backwards, you will have low voltage on pin 16 and the regulator will get hot. The notch on U1 must point toward the rear of the board. 73, Don W3FPR On 12/23/2014 5:01 AM, Benjamin Schmid wrote: Hi everybody, I'm currently in the middle of building my K1 #3343.

A $5 pair of long-reach surgical forceps or hemostats will do the job without unnecessary disturbance to major organs. Remove only the rear fan panel, and then it's easy to reach down behind the KPA3 using the hemostats to remove RFC48 and F2. Lightly clip the hemostats onto the component and then unsolder from underneath. After clearing the holes of solder, use the hemostats again to insert each new component from above. Easy! Hemostats are readily available as craft tools on eBay for only a few $/£/EUR, and the 6-inch straight pattern is probably the first one to buy. 73 from Ian GM3SEK __ 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 Message delivered to arch...@mail-archive.com
