Re: [Elecraft] Antenna comparisons, WSPRnet and timed serial port macros
Put it into TX on a dummy load and run your batch file and find out! 73 de David, M0XDF (K3 #174, P3 #108) On 7 Aug 2013, at 04:35, drewko wrote: Ray, Tks again for the idea.

Re: [Elecraft] Antenna comparisons, WSPRnet and timed serial port macros
Even with dummy loads connected I'd hesitate to hot switch ANT. Perhaps could try it while transmitting at 0 watts? 73, Drew AF2Z On Wed, 07 Aug 2013 09:25:24 +0100, you wrote: Put it into TX on a dummy load and run your batch file and find out! 73 de David, M0XDF (K3 #174, P3 #108) On 7 Aug 2013, at 04:35, drewko wrote: Ray, Tks again for the idea.

[Elecraft] Antenna comparisons, WSPRnet and timed serial port macros
I've been doing some performance comparison between two antennas I am using. I'm compiling data of my WSPR transmissions and spots over periods of many hours. I got a little carried away and made up a spreadsheet to compare reciprocal signal reports as well as the performance differences between my two antennas... Basically, I am manually switching from one antenna to the other on a reqular basis, keeping track of which time periods each is in use. What I'd like to do is automate the antenna switching on my K3 at periodic intervals. The question is, what is the simplest solution for achieving this? Don't really want to install some full-blown logging-control software. I am wondering if there is perhaps some little generic utility available that will send user specified commands over the serial port at specified intervals. Is there anything like that available? (Years ago there was a great telecom program called COMMO that could do this.) 73, Drew AF2Z __ 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] Antenna comparisons, WSPRnet and timed serial port macros
Here is a link that may answer part of the question: http://batchloaf.wordpress.com/2013/02/12/simple-trick-for-sending-characters-to-a-serial-port-in-windows/ His simple method of doing echo hello or your command string to com1 would probably work. You could then make that a batch file to be run periodically. While I am not currently a Windows user I seem to recall an ON command that can schedule things. Hope this helps.

Re: [Elecraft] Antenna comparisons, WSPRnet and timed serial port macros
Get a mechanical timer, one that has the pegs in a wheel to set on and off times to control a lamp etc. Set up an antenna relay that connects one antenna when power is on, and the other when off. 73 - Mike WA8BXN ---Original Message--- From: drewko Date: 8/6/2013 12:36:39 PM To: Elecraft@mailman.qth.net Subject: [Elecraft] Antenna comparisons, WSPRnet and timed serial port macros I've been doing some performance comparison between two antennas I am using.

Re: [Elecraft] Antenna comparisons, WSPRnet and timed serial port macros
Brian, Yes, I want to send the ANT 1/2 switch command to the K3, say every quarter hour. I believe there is no serial port rig control from the WSPR software to contend with, just the tones from the soundcard that key the rig periodically. So, I just need a utility to send the ant switch command over the serial port to the K3 at fixed intervals. Actually, I have found an old copy of COMMO that may run in a DOS window. I'll try it later but if someone knows of a more recent similar program pls let me know, thanks. 73, Drew AF2Z On Tue, 06 Aug 2013 17:02:50 +, you wrote: Drew, Do you mean K3's internal antenna 1/2 or some external antenna switch? If K3's internal: Try the commands AN1; and AN2; in the firmware update program to see if it does what you want. That command can easily be programed in a stand alone program. If you are using rig control in WSPR, then you would need to share the COM port with a program like LPBRIDGE. If external box, then you can kluge something mechanical/electrical up to do the switching at prescribed intervals. 73 de Brian/K3KO On 8/6/2013 16:36, drewko wrote: I've been doing some performance comparison between two antennas I am using.

Re: [Elecraft] Antenna comparisons, WSPRnet and timed serial port macros
Ray, Thanks! That's what I had in mind... I believe it is the AT command (not ON). Also, SCHTASKS perhaps... 73, Drew AF2Z On Tue, 06 Aug 2013 12:52:57 -0500, you wrote: Here is a link that may answer part of the question: http://batchloaf.wordpress.com/2013/02/12/simple-trick-for-sending-characters-to-a-serial-port-in-windows/ His simple method of doing echo hello or your command string to com1 would probably work.
