[Elecraft] K3 Diversity with 2 RX antennas
How would I set up the K3 in diversity mode with two different RX only antennas? One to the RX antenna and one to the AUX RF? Would going into diversity mode with that setup get me one RX antenna in one ear and the other RX antenna in the other? 73, Ken, K6LA / VY2TT __ 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

Ken, Yes, that is how you would set it up - you need to select RX ANT for both the ain and the SUB.

[Elecraft] XG50 - Frequency Instability
I am trying to use my XG50 to run the Extended Temperature Compensation Procedure on my KX3. This is the first time I have attempted to use the XG50 since building it. I have completed the 8 hour burn-in. When I first connect the XG-50 to my HP frequency counter, I get a reading of something like 49.379990. Then after running for several minutes it starts dropping in frequency to something more like 49.32. It is still wildly fluctuating.

Re: [Elecraft] K3 Diversity with 2 RX antennas
Ken, Yes, that is exactly the way to do it, and that still allows you to transmit through the main antenna. So in other words, you would select RX ANT for the main receiver, and be sure to select the AUX input for the sub-receiver (while b SET is engaged, tap the ANT button on the K3 to alternate between MAIN and AUX and be sure you leave it on AUX.) I operate this way on both 40m and 30m with a Pixel Technologies loop connected to the AUX input, and a small voltage probe RX antenna connected to the RX ANT input of the K3, while using a ground plane vertical as the main transmit antenna. Depending upon the amount of power you're using, and the proximity of the rx antennas to the tx antenna, you may want to consider adding some outboard rx protection. I use the Array Solutions Model AS-RXFEP, and it works very well. 73, Dale WA8SRA How would I set up the K3 in diversity mode with two different RX only antennas?

[Elecraft] XG50 - Frequency Instability
Gary, I used my XG3 for doing the temperature compensation procedure and continuously monitored its frequency with my EIP538 counter (has TCXO reference). I ran the XG3 from external 13.5v to ensure constant level and had it running 30-minutes in advance to ensure it was stabilized. I noted only about +/- 1 to 2 Hz variation in the signal during the whole procedure. My attempts to use the 5th overtone of my 10-MHz OCXO was unsuccessful due to the harmonic level not being high enough. I didn't try banging a diode to produce higher level harmonics. I am fairly satisfied the XG3 was adequately good enough for doing the procedure. I suspect your A/C is causing a cold draft producing the drift you are seeing. Try enclosing in inside an insulated box. We have no A/C here in Alaska. If it gets warm enough we open what are called windows! But I used to live in SoCal so understand the need down there! 73, Ed - KL7UW --snip My lab is in my photographic darkroom which has an ambient temperature of about 68 degrees F and the AC does blow across the work area.

50-60 kHz instability of a 49 MHz source is over 1000 ppm, two or three orders of magnitude greater than would be expected, even with air conditioning blowing across the oscillator.

Re: [Elecraft] Interfacing TS480 to KPA500
Mike; First, the KPA serial ports are _not_ pass-through. Each has a specific purpose and don’t actually work together. How you set up the XCVR serial port connection depends entirely on whether there is a computer in the situation or not, and whether that computer polls the radio for information. Since this is a remote base, can we assume that a computer is involved and it is getting info from the radio? If so, then you need to set up the KPA500 so that it simply eavesdrops on the conversation. You will need to fabricate a Y adapter for this. In the case of the KPA all signals can go through, but realistically you only need pins 2, 3, 5 and (I believe) 8 connected. Pin 8 is the handshake pin for the TS480, and is needed to allow the radio to send data on the RS-232 port. It does not need to be connected to the KPA500 port, but if it is the KPA will simply ignore it. Note that the KPA does not make a connection to that pin, so if you set the station up without a computer, you will need to provide +12V for that signal to allow the TS480 to talk. As the manual indicates on page 12, there are three menu items involved with this situation. You will need to set the RADIO item to SERIAL, then set the RS232 X item to the appropriate data rate. Finally, since the computer is polling the radio for data, set SER POLL to OFF. If there is nothing doing the polling, you will need to set this item to ON to allow the KPA to do this task. With this setup, things should work just fine. But we aren’t finished, you did mention a KRC2, so let’s discuss that. I would suggest inserting the KRC2 in between the TS-480 and the KPA500. Make sure that only pins 2, 3 and 5 go to the KRC2 ports. That pesky TS480 handshake signal should not go through the KRC2 without making changes inside the KRC2. What changes? Disconnect the W jumpers for the handshake pins and then jumper across the connector side of the pins so that the signal gets passed from one DE9 to the other. Then set the serial port data rate jumpers for the appropriate rate. The KRC2 can do 4800, 9600 and 19200 bps with the V1.6 firmware. You probably want to run as fast as you can on the serial port, which means 19200 bps. You can then plug the serial port cables into their appropriate connectors and try things out. Be sure to check to make sure that pin 8 is the handshake pin needed for the TS480. I think it is that pin, but will need to check it. Also look at the KRC2 manual for the proper W jumpers. I’ll also take a look and privately email you what I come up with. Your station should work quite well in this configuration. Good luck! 73, Jack Brindle, W6FB Elecraft Engineering On May 22, 2014, at 7:38 AM, Michael Walker va...@portcredit.net wrote: All My remote base runs on a TS480 and I will be adding a KPA500 to the mix.

Re: [Elecraft] Heatsink confusion
Hi Phil The times you would need a heatsink is when running PSK31, RTTY, AM and FM. These are all continuous duty and make the KX3 produce heat faster than it can be dissipated. I tend to rag chew on PSK31 so I added the large heat sink by VE7FMN to my KX3. I had to run a 3 inch fan before to work PSK31 but now with that heat sink I do not need the fan. I did use Radio Shack Heat Sink Compound 276-255 under the two final transistors and under the new heat sink. I don't know if it is needed but after 35 years of doing that kind of work I consider that to be standard procedure. I never had any problem running CW or SSB with the KX3 causing overheating although I understand if you place the KX3 in bright sun lite it will overheat even in receive mode. That is because the black color absorbs sunlight heat. I have had other equipment such as handy talkies get too hot under the same sunlight conditions. I hope this information helps. If you work only SSB and CW don't worry about it. if you work a continuous duty mode I think VE7FMN has the best heat sink and he sure worked well with me as I do not belong to Pay Pall so he had to accept a money order. We exchanged several E-Mails and as I said he was great to do business with me. 73 Ken W0CZ w0cz at i29 dot net Sent from my iPad On May 21, 2014, at 11:39 AM, Phil Hystad phys...@mac.com wrote: When do you need the heatsink?

Hi Jack Thanks for the detailed reply. Yep, I am aware of all the RS232 gotchas with the KRC2. :) I have mine wired to handle the handshaking as well.

Since this is a remote base, can we assume that a computer is involved and it is getting info from the radio? If so, then you need to set up the KPA500 so that it simply eavesdrops on the conversation. You will need to fabricate a Y adapter for this. In the case of the KPA all signals can go through, but realistically you only need pins 2, 3, 5 and (I believe) 8 connected. Pin 8 is the handshake pin for the TS480, and is needed to allow the radio to send data on the RS-232 port. It does not need to be connected to the KPA500 port, but if it is the KPA will simply ignore it. Note that the KPA does not make a connection to that pin, so if you set the station up without a computer, you will need to provide +12V for that signal to allow the TS480 to talk.

Disconnect the W jumpers for the handshake pins and then jumper across the connector side of the pins so that the signal gets passed from one DE9 to the other. Then set the serial port data rate jumpers for the appropriate rate. The KRC2 can do 4800, 9600 and 19200 bps with the V1.6 firmware. You probably want to run as fast as you can on the serial port, which means 19200 bps. You can then plug the serial port cables into their appropriate connectors and try things out.

[Elecraft] N0SS website is still on-line
Hello all, Those who remember Tom Hammond N0SS (SK) will likely recall that he had a wealth of information related to Elecraft and other ham radio things on his website. I was delighted to find out when at Dayton that this website is still available. It has been replicated under the MMARC website - that is the club that Tom belonged to Mid Missouri Amateur Radio Club. You can go to http://www.mmccs.com/mmarc/ and click on the N0SS box in the lower left corner or use the direct link http://www.mmccs.com/mmarc/n0ss/. Note that this is a static website, no boards or kits mentioned are available, but Tom documented his board patterns nicely for those who might want to roll your own. Now that I know where to find the website, I will be updating the external links on my website that referred to Tom's information. My thanks go out to the MMARC for preserving this information. Owners of the Elecraft K1, KX1, K2 and K3 especially will find a lot of helpful information.

Re: [Elecraft] Interfacing TS480 to KPA500
I have found while trying to interface the TS-480SAT with my computer and my SPE Expert 1K that I have not been able to make everything work the way it does with my K3. The RS-232 port on the TS-480 seems to want the computer to be the master and if connected to the computer it does not spontaneously transmit data. So, if the TS-480 is connected to the amp directly with the RTS and DTS shorted it works with the amp but will not accept CAT data from the computer. If it is connected directly to an RS-232 port on the computer the TS-480 will not send data to the amp. If you unplug the computer and plug in the amp, the data goes to the amp or the data from the computer will go to the amp and the TS-480. It is a bit difficult to grasp, but the bottom line with both amp and computer connected any command to change bands from the computer is executed in both the transceiver and the amp, but any commands to change frequency from the TS-480 are not executed until you transmit and the frequency counter in the Expert detects the new frequency. I do not know how this compares with the KPA-500. My K3 has a band decoder in the accessory plug and will change the amp band when the band is changed either by a K3 control or by the Computer. I will enjoy following this thread to find out where you go with this. RS-232 seems to be so flexible that each new combination of equipment is an adventure.

Re: [Elecraft] Stackable Binding Post (BNC-BP)
Joshua, You will want to use 2 - 1/4 wavelength wires - one for the radiator and the other for a counterpoise. It may work with just the radiator wire, but then the 'counterpoise' will be the case of the transceiver and your body and anywhere else the RF return path thinks it needs to be. With the counterpoise wire in place, that provides the RF return path and eliminates changes in tuning (SWR variation) depending on where you position the transceiver and your body. 73, Don W3FPR On 5/22/2014 7:52 PM, Joshua Gould wrote: Greetings, I have yet another question...

Re: [Elecraft] Stackable Binding Post (BNC-BP)
A wire laying on the ground will have more capacitive loading and will electrically longer, so it can be shorter than a 1/4 wave. But all this depends on lots of assumptions, so just throw some wire out there and have fun. One common random length is a 26' foot wire in the air and a 16' wire on the ground. wunder K6WRU http://observer.wunderwood.org/ On May 22, 2014, at 6:27 PM, Don Wilhelm w3...@embarqmail.com wrote: Joshua, You will want to use 2 - 1/4 wavelength wires - one for the radiator and the other for a counterpoise.

Re: [Elecraft] [KX3] N1MM and keying KX3. What happens to the slashes // Solved

I think that precludes using a paddle though.

Re: [Elecraft] XG50 - Frequency Instability - Resolved
First I want to thank those that pointed out that my first two postings didn't contain message content, probably due to using HTML. You were right, I changed the default for this email program to plain text. Second thank you to the responders that suggested solutions to my instability non-problem. Turns out it was the input level to the HP 5334A. Adjustment of the counter nailed it pretty close. Stabilized at 49.38 MHz +-2 Hz. 73 Gary Marklund KJ7RT Sun City, AZ USA Original Message Subject: [Elecraft] XG50 - Frequency Instability From: kj...@kj7rt.com Date: Thu, May 22, 2014 7:31 am To: Elecraft@mailman.qth.net I am trying to use my XG50 to run the Extended Temperature Compensation Procedure on my KX3. This is the first time I have attempted to use the XG50 since building it. I have completed the 8 hour burn-in. When I first connect the XG-50 to my HP frequency counter, I get a reading of something like 49.379990. Then after running for several minutes it starts dropping in frequency to something more like 49.32. It is still wildly fluctuating. If I connect the 10MHz output of my Trimble Thunderbolt GPSDO to the counter it stays quite stable just below 10 MHz. I re-soldered all the XG50 components and tried with both a metered home-brew power supply and a 12v SLA battery with the same result although re-soldering made a significant but not permanent improvement. My lab is in my photographic darkroom which has an ambient temperature of about 68 degrees F and the AC does blow across the work area.

[Elecraft] N0SS website is still on-line
Yes, Don, the callsign N0SS is also kept by the club. I still regret that I did not meet Tom in Dayton 2011. 73 Johnny VR2XMC 寄件人︰ Don Wilhelm w3...@embarqmail.com 收件人︰ 'Elecraft' elecraft@mailman.qth.net 傳送日期︰ 2014年05月23日 (週五) 3:44 AM 主題︰ [Elecraft] N0SS website is still on-line Hello all, Those who remember Tom Hammond N0SS (SK) will likely recall that he had a wealth of information related to Elecraft and other ham radio things on his website. I was delighted to find out when at Dayton that this website is still available. It has been replicated under the MMARC website - that is the club that Tom belonged to Mid Missouri Amateur Radio Club. You can go to http://www.mmccs.com/mmarc/and click on the N0SS box in the lower left corner or use the direct link http://www.mmccs.com/mmarc/n0ss/. Note that this is a static website, no boards or kits mentioned are available, but Tom documented his board patterns nicely for those who might want to roll your own. Now that I know where to find the website, I will be updating the external links on my website that referred to Tom's information. My thanks go out to the MMARC for preserving this information. Owners of the Elecraft K1, KX1, K2 and K3 especially will find a lot of helpful information. RIP Tom and Jeri. 73, Don W3FPR __ 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 vr2...@yahoo.com.hk __ 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
