Thanks for that. I never understood the Ameritron ALC instruction for my ALS-600 so I just never used the ALC. That attached instruction was much clearer and made sense.

Until such an interface is available, however, I’m forced to stick with the current solution of using a PC, virtual serial port(s), serial-to-ethernet converter, and KAT500 utility software. Much about remote operating boils down to personal preference. There is no ‘right’ answer; rather how one uses their station, lessons learned over time, and new technical offerings will cause evolution of how ‘best’ it can be done on a case-by-case basis.

Re: [Elecraft] [ELECRAFT] KPA500 NEW OWNER QUESTIONS.......
Many years ago, I built a tube amplifier with what I thought was a fairly sophisticated ALC circuit. I could never get the ALC loop to be stable. I know a lot more about control systems now, but I still don't know how to get ALC around an amplifier to work, and apparently neither does anyone else. What I don't understand is why it's so hard with an external amplifier, as every transmitter has ALC for its internal 100 W amplifier, and that works fine. Why the same design doesn't work with an external amplifier is the mystery. The problem with just limiting the drive power and using the transmitter's ALC is that, especially for solid state amplifiers, the required drive power can vary considerably with SWR and temperature. That requires either riding the power control continuously or running your amplifier well below rated output most of the time. (Unless, of course, you're running a 2.5 kW amplifier, but that kind of margin is expensive.)

This port can however only be used for the rotor, plus the web interface and virtual serial port can not be used at the same time. To further clarify: The RC-1216H can be configured to manage the KPA-500, the SteppIR, ACOM-200A, Expert 1K-FA, and specific rotators. According to the RC-1216H manual, “At the moment it support Prositel rotators with the D-type control box, AlfaSpid rotators, rotators controlled by Green Heron control box and other rotators with serial interfaces with the DCU-1 protocol.” In my case, the RC-1216H is compatible with the Green Heron RT-21 control box. Along with managing the rotor direction, jt can also power on/off the Green Heron controller through a relay box (such as from West Mountain Radio) that allows 12 VDC to power on/off a 120 VAC device. Keep the Green Heron power switch set to ‘on’ and I have remote on/off capability for the Green Heron itself through the RC-1216H. Thus, I have two RC-1216H devices: one to manage the KPA500 and the other to manage my Green Heron/Orion rotor system. The Webswitch 1216H is certainly an alternative for rotor control and people do get confused with the two model designations. When I ordered the RC-1216H from HRO, they sent me the webswitch 1216H in error. I like the RC-1216H because it is a simple RS232 cable connection between the RC-1216H and Green Heron; configure the RC-1216H to manage a rotor, and it basically works out-of-the-box.There are eight predefined aziumth bearings that can be labeled as well as the ability to direct the antenna to a specific bearing. In summary, the trend is for more seamless web-based management of remote devices both in the consumer market and amateur radio as it eliminates the need for specific hardware/software to remotely manage devices. If I could replace using KAT-500 Utility software with a web-based device such as the RC-1216H to manage the tuner, I could stick with running Apple devices (and avoid running Windows under Parallels on a MacBook Pro) and be able to fully control my K3 station from anywhere (in conjunction with the K3/0-Mini). 73, Barry, WD4ASW (Keller, TX) 73, Mitch DJ0QN / K7DX -- Mitch Wolfson K7DX / DJ0QN 10285 Boca Cir, Naples, FL 34109 Skype: mitchwo USA: Home:+1-239-221-9600 - Mobile:+1-424-288-9171 Germany: Home:+49 89 32152700 - Mobile/WhatsApp:+49 172 8374436

And now the voice of caution. I think the KPA500 with the KAT500 and my Flex are a wonderful combination. That said, my KPA500 stopped working. It appears, after reviewing the logs, I hit it with 75 watts and probably blew one of the diodes in the front end. I can dig up the explanation if needed. It may have been a case where it took me a while to realize what I was doing. In fact, I can't remember the event other than it was logged by the KPA500. By the way... just having that log available is valuable.

My favorite ones are the Lantronix > UDS2100, which I have bought over Ebay. I’m currently using the Lantronics EDS4100 serial-to-ethernet which works well. As you note, one creates a virtual com port on the controlling PC running Windows. This device can manage up to four serial ports at the remote site. Thus, I have the virtual com configuration installed on Win-7Pro machine in the shack as well as on a Win10Pro virtual machine running on my MacBook Pro running Parallels that’s with me. However, that’s the problem… I want to use web-based devices because I have no desire to run a Windows in the shack or where I am. A web-based device such as the RC-1216H is much more convenient, doesn’t require a PC to access and avoids having to specially configure the controlling computer such as is required to manage a Lantronics device that is only compatible with Windows OS. I can’t tell you how many times I’ve used my iPhone, iPad, MacBook Pro, etc. to remotely manage my station to turn on/off devices (through West Mountain Radio’s 4005i) or even reboot computers (through Digital Loggers Pro Switch). > > Note that the WebSwitch 1216H (not the RC-1216H) allows rotor control and > also has a serial port server to provide a virtual serial port.

To further clarify: The RC-1216H can be configured to manage the KPA-500, the SteppIR, ACOM-200A, Expert 1K-FA, and specific rotators. According to the RC-1216H manual, “At the moment it support Prositel rotators with the D-type control box, AlfaSpid rotators, rotators controlled by Green Heron control box and other rotators with serial interfaces with the DCU-1 protocol.” In my case, the RC-1216H is compatible with the Green Heron RT-21 control box. Along with managing the rotor direction, jt can also power on/off the Green Heron controller through a relay box (such as from West Mountain Radio) that allows 12 VDC to power on/off a 120 VAC device. Keep the Green Heron power switch set to ‘on’ and I have remote on/off capability for the Green Heron itself through the RC-1216H. Thus, I have two RC-1216H devices: one to manage the KPA500 and the other to manage my Green Heron/Orion rotor system. The Webswitch 1216H is certainly an alternative for rotor control and people do get confused with the two model designations. When I ordered the RC-1216H from HRO, they sent me the webswitch 1216H in error. I like the RC-1216H because it is a simple RS232 cable connection between the RC-1216H and Green Heron; configure the RC-1216H to manage a rotor, and it basically works out-of-the-box.There are eight predefined aziumth bearings that can be labeled as well as the ability to direct the antenna to a specific bearing. In summary, the trend is for more seamless web-based management of remote devices both in the consumer market and amateur radio as it eliminates the need for specific hardware/software to remotely manage devices. If I could replace using KAT-500 Utility software with a web-based device such as the RC-1216H to manage the tuner, I could stick with running Apple devices (and avoid running Windows under Parallels on a MacBook Pro) and be able to fully control my K3 station from anywhere (in conjunction with the K3/0-Mini). 73, Barry, WD4ASW (Keller, TX) > > 73, > Mitch DJ0QN / K7DX > > -- > Mitch Wolfson K7DX / DJ0QN > 10285 Boca Cir, Naples, FL 34109 > Skype: mitchwo > USA: Home:+1-239-221-9600 - Mobile:+1-424-288-9171 > Germany: Home:+49 89 32152700 - Mobile/WhatsApp:+49 172 8374436 > __ 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] [ELECRAFT] KPA500 NEW OWNER QUESTIONS.......
Yes, improperly or incorrectly using ALC with any amp or any transceiver, for that matter, can and usually does produce distortion and splatter. Just look at some of the signals on the bands and observe the ALC overshoot which exists with many radios. And it is made worse by the addition of an amplifier in line. It isn't pretty!. Yet it has little impact on the on frequency signal as heard and thus the "great signal" complements follow. But look at the other factors where you will find "NOT so great signal". These points should be addressed as well. 73 Bob, K4TAX On 2/28/2019 1:04 PM, j...@kk9a.com wrote: I have not used ALC with any amplifier since transceivers switched to transistor finals.

Re: [Elecraft] KPA500 new owner questions.......
I agree with Rick just keep the drive power to the minimum needed to get the 500 watts out. Over driving will do nothing but distort the signal and most likely eventually damage the amp. I use 18 to 20 watts to get 500 out on 160 mtrs and a bit more to get same results on the higher bands.

Re: [Elecraft] KPA500 new owner questions.......
When I read in the manual where it says "never exceed 40 watts" that leads me to believe one should not do that. While the protection circuit is fast and there is a 3 dB attenuator that switches in automatically, from 100 watts down 3 dB is still over 40 watts. I think I read here where someone hit the amp with 100 to 200 watts and now it needs repair. In other words, "they let the smoke out of the box". As to ALC, that is in my opinion and option and does not require the company to supply a cable or diagram. After all, what connector type for "other radio" is required? And in many cases, mine for one of my radios, there is NO ALC input. Thus I must BE VERY CAREFUL when I use that radio with my KPA500. As to using ALC, since your IC-7300 does have provision for external ALC, my suggestion is USE IT!. Page 17 in the manual "Using ALC" is quite clear about this. And for what it's worth, with my K3S, I do have the ALC interfaced from the amp to the radio. Just in case something goes amiss. With my radio that does not have ALC input, I must be careful to set the power correctly and then CHECK and RECHECK to see all is done correctly before transmitting. My KPA500 is in line in all station configurations and operation. Two transceivers, 160M - 6M. I find no need to physically or externally switch it out of line. 73 Bob, K4TAX On 2/28/2019 12:07 PM, Jim Lageson wrote: I have never owned an amp before and recently put together a KPA500.

Re: [Elecraft] KPA500 new owner questions.......
The fault ability of the KPA500 is fast, BUT I would not test that with 100 watts. The tuned input can only take so much abuse. ALC should be used as a secondary (emergency) limiter, not for everyday use. It will cause distortion (in part from overdriving the amp). Proper management of the input (power out, proper compression levels etc) is THE best way to manage the combination.

Re: [Elecraft] new K3/0 Mini
Barry, I have been using serial to ethernet servers for over 10 years to control rotors, amplifiers and other serial devices. You set these up once and can forget about them. You install a virtual serial port on the control PC for which you can use any kind of client software to control that device, but there is of course no web interface. No local PC on the radio side needs to be running. I use these devices instead of the (expensive) dedicated RC-1216H devices that only provide a web interface. My favorite ones are the Lantronix UDS2100, which I have bought over Ebay. Note that the WebSwitch 1216H (not the RC-1216H) allows rotor control and also has a serial port server to provide a virtual serial port. This port can however only be used for the rotor, plus the web interface and virtual serial port can not be used at the same time. 73, Mitch DJ0QN / K7DX -- Mitch Wolfson K7DX / DJ0QN 10285 Boca Cir, Naples, FL 34109 Skype: mitchwo USA: Home:+1-239-221-9600 - Mobile:+1-424-288-9171 Germany: Home:+49 89 32152700 - Mobile/WhatsApp:+49 172 8374436 On 28.02.2019 11:56, Barry Baines via Elecraft wrote: Fred: On Feb 28, 2019, at 8:20 AM, Fred Massey wrote: A K3/0 that could directly connect over the internet with a K3s (K3s+ or K4) is really needed.

Overall, the system works very well and I’ve been using it since September 2014 without problems. I now keep a K3/0-Mini system at two different locations (Texas and New England) both of which cannot support a ham station on site. The Flex System overcomes some of the weaknesses of the K3 approach and of course it has a remote panadapter capabiity. But it has taken Flex over five years to provide the remote capability at significantly higher cost and requires greater upload bandwidth. SmartSDR 2.0 was introduced in 2017 which means for four years I could only operate the Flex-6700 when at the shack. Flex’s approach is dependent upon a server-based system to establish a secure link, a license fee if you’re upgrading from Version 1 to Version 2 or Version 2 to (just announced) Version 3 of SmartSDR. Flex Radio has to maintain a server system to control access remotely. The PGXL amplifier can be controlled directly through Maestro or a PC running SmartSDR v2.xx operating from a remote site. However, the “Tuner Genius” that is promised to go with the PGXL has not been released, so I’m limited to using my EFHW antenna to the KAT500 and the K3 setup since I do need to use a tuner with it. I will say that the bandwidth requirements of the Flex under the current V2.49 SmartSDR is significantly less than in the past so it works more reliably in “Low Bandwidth" mode. I also keep a Maestro in both Texas and New England. Having two different remote systems with different feature sets does provide some advantages: -Redundancy. In the event one system has a remote issue, I have the other to use as a backup. -Flexibility. I like to ‘listen’ so much of my time is spent listening or participating on nets.

Re: [Elecraft] new K3/0 Mini
That is something that I requested some years ago and again this year. To make a box that allows control of the K3(S) using the same port as the KPod plus a connection to Line in/out for audio. Using something like an FPGA, with networking integrated, it appears to be a simple matter to convert the K3(S) into a network device (but WELL above my ability level), which would simplify remote operations without the need for a computer (and capable of using battery power). A matching app (or at least the data exchange) would complete this; tablet ops are pretty nice, BlueTooth to the tablet/phone for managed audio. I've worked around it with a computer, TeamViewer and Skype, but there is no reason it can't be simplified. Using the phone internet, one could put up a remote where needed (EMCOMM or fun). I really think that it would be a very useful addition to the K Line; when they have the time. It would place the K3(S) next to the Flex for simpler remote ops. The app should also consider management of an amp, tuner, rotor or other auxiliary devices; if it gets that far. Rick NHC On 2/28/2019 8:05 AM, Peter Dougherty wrote: I couldn't agree more.

Flex Radio has to maintain a server system to control access remotely. The PGXL amplifier can be controlled directly through Maestro or a PC running SmartSDR v2.xx operating from a remote site. However, the “Tuner Genius” that is promised to go with the PGXL has not been released, so I’m limited to using my EFHW antenna to the KAT500 and the K3 setup since I do need to use a tuner with it. I will say that the bandwidth requirements of the Flex under the current V2.49 SmartSDR is significantly less than in the past so it works more reliably in “Low Bandwidth" mode. I also keep a Maestro in both Texas and New England. Having two different remote systems with different feature sets does provide some advantages: -Redundancy. In the event one system has a remote issue, I have the other to use as a backup. -Flexibility. I like to ‘listen’ so much of my time is spent listening or participating on nets. The K3 setup works well since I’m not particularly “hunting” for signals where a panadapter would be useful. Simply turn on the K3 and I’m on the last frequency I was tuned or I can enter the frequency of interest. I have the tuner and amplifier as needed, and 500W is usually more than sufficient for my needs.The Flex is more helpful if I’m searching the bands with a panadapter/waterfall, but the PGXL is only helpful on 10-15-20 where I have a yagi and don’t need to a tuner capable of handling the PGXL. Due to bandwidth issues, the Flex system does sometime ‘hiccup’ due to missed packets though this happens a lot less than previously. -Space. I spend 90% of my operating time running remote. At my locations in Texas and New England I have the Maestro and K3/0-Mini sitting on my 30” x 60’ office desk by the 27” Apple Display with West Mountain Radio external speakers that can be used with either system. The Remote Rig equipment, cabling, network ethernet switch, 120 VAC surge protected hub that powers the Remote Rig equipment, network switch, Maestro, Speakers, K3/0-Mini are either sitting on the floor or held in place with cable ties attached around the desk legs, out-of-the-way and out-of-sight. Of course, the ham shack itself in Georgia is a different matter given the amount of equipment installed, but the
Re: [Elecraft] new K3/0 Mini
It would be ideal to also include the band scope of the p3 into the solution. Perhaps the integration of the solution could be encapsulated into a new P3. The functionality of remoterig can be in the new P3, and the P3 scope data could be sent digitally over the internet as well.

Re: [Elecraft] new K3/0 Mini
I couldn't agree more. I'd buy the hell out of that combination. I'd go further, and would like to see a smaller physical sized remote for easy traveling. Fewer physical controls but much less size and weight. - pjd -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Fred Massey Sent: Thursday, February 28, 2019 9:20 AM To: Jorge Diez - CX6VM Cc: Elecraft Reflector Subject: Re: [Elecraft] new K3/0 Mini A K3/0 that could directly connect over the internet with a K3s (K3s+ or K4) is really needed.

Re: [Elecraft] KX3 - After temperature compensation procedure - continues to show drift?
Hi Mike, I had to perform the temp compensation a few times. A couple of those times necessitated a retry due to operator error in the setup :-) I eventually achieved a level of proficiency in preparing to apply the heat source. Initially, I used a hair dryer the first couple of times. But the drift was still present. I then used an incandescent light bulb (60W I believe) in a small articulated desk lamp. This worked much better as the temp rise was more consistent over a longer period of time. After that successful calibration, I have yet to see any drift or be called out for having drift by another ham. The KX3 temp compensation is brilliant for a fanless rig once it is calibrated correctly. regards, Brian VE3IBW On Thu, Feb 28, 2019 at 9:07 AM Mike Parkes wrote: > The other day I finally got up the nerve to perform the temp compensation > procedure on my KX3.

A K3/0 that could directly connect over the internet with a K3s (K3s+ or K4) is really needed. The remoterig is relatively difficult and old tech.

[Elecraft] KX3 - After temperature compensation procedure - continues to show drift?
The other day I finally got up the nerve to perform the temp compensation procedure on my KX3. The process went fine as far as I could tell (the Elecraft instructions we great), I tried very hard to limit the temp rise to only one degree every min or two. So then this morning, I am looking at my WSPR mode results on 80 meters. At 2 watts I am still being occasionally reported as drifting 1hz drift, mostly negative, (and saw one -2 hz drift). I seldom run more than 2 watts any more, and the rig only gets barely warm at 2.

I will wait until I can get some reports on 20 meters wspr, because I know it was showing 2-4 hertz drift/minute drift on that band at 2 watts, it will be interesting to see what it shows now if the band opens some.
