Re: [Elecraft] New P3 command and Macros...
I see. That will be very useful. Now all I will need is a save/restore function for the center frequency and the span. I use fixed mode and have set up those parameters differently for each band. For example, on 18 MHz I have the center set to 18.084 and the span to 32 kHz. That gives me a fixed display of 18.068 to 18.100. If I had #RCF and save/restore, I could make one macro to save and drill down to the pileup, and another to restore to the normal setting. The #RCF would allow me to restore the center, as long as I didn't change VFO A! But I often fiddle with it. And my span is different on different bands. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 27 Feb 2016 21:41, Alan wrote: The #RCF+002500 command moves the P3 center frequency to 2.5 kHz above the K3 VFO A frequency.

Re: [Elecraft] New P3 command and Macros...
The #RCF+002500 command moves the P3 center frequency to 2.5 kHz above the K3 VFO A frequency. It works in both tracking and fixed-tune mode, except that if it places the VFO cursor off-screen in fixed-tune mode, the P3 may automatically change its center frequency again to keep it on screen, depending on the setting of the FixMode menu setting.

Re: [Elecraft] New P3 TX Monitor....unusual behavior with SWR (at times)
I had a similar problem -- even at low power levels, the W2 would periodically spike a high-SWR and even show 2-3 bars of SWR when no signal was present. I swapped out the 8-pin cable connecting the sensor to the W2 and the problem went away. I re-crimped the connectors on the original cable, but haven't yet swapped it back in to see if doing so fixed the problem. On Wed, 12 Aug 2015, Randy Farmer wrote: I find this thread quite interesting. I too have been dealing with VSWR spurts. My TX lineup is similar to Phil's, but I don't have the TX Monitor. After a recent station rewiring job I found I was having a great deal of trouble with indicated VSWR jumping to high levels with the amplifier on. The problem was especially bad on 80 meters -- anything above about 300W would randomly give a high VSWR fault on the KAT500. Since the KPA500 was feeding the suddenly changed load it too would usually fault out. The sensor for my LP-100A is on the antenna side of the KAT500, and its VSWR indication was rock solid during these events. My station is in an extremely difficult RFI environment, with seven antennas crammed onto a 0.2 acre city lot. I immediately suspected that common mode RF was getting into the reverse power sensor circuit in the KAT500. I installed a Balun Designs choke on the antenna side of the LP-100A sensor and the KAT500 stopped giving the high VSWR indications right away. That's the good news. The bad news is that now the KPA500 is doing it, but at considerably higher power levels. I can run around 400W out before the KPA500 begins to randomly show VSWR faults. The KAT500 is completely stable at full power. For now, I'm living with this situation. So I would suggest the troubles you're seeing may be the result of common mode RF problems on the transmitter feedline. It could be that the addition of the extra electrical length of the TX Monitor sensor and its associated cabling changed things just enough to put a common mode voltage node near the KAT500 output port. You might try adding an additional piece of coax somewhere in the lineup and see if that changes the situation. RF is funny stuff. 73...

Re: [Elecraft] New P3 TX Monitor....unusual behavior with SWR (at times)
Having the LP-100A on the antenna side is by design. I'm not much interested in monitoring the antenna VSWR in real time, but I do want to know the power being delivered at the tail end of the station RF lineup. The light show on the KAT500 and the KPA500 (if it's being used) as well as the internal indication in the K3 gives plenty of redundant information about whether or not the antenna tuner is doing its job. The unique vector measurement capability of the LPA-100A also makes it good for maintenance checks. I periodically run the utility program to have the LPA-100A measure the various antennas across their operational bands and compare the results against historical data. This lets me see any changes that might have occurred -- these changes would be masked by an antenna tuner between the LPA-100A sensor and the actual antenna. I actually use the KAT500 almost exclusively for tuning my 80 meter inverted L, which is too long electrically but mechanically impossible to tune properly. Although all my other antennas are resonant on their respective operating bands I also leave the KAT500 on line to use as a line flattener on 160 and 40 meters if I should operate outside of the normal CW bands these antennas are tuned for. 73...

Re: [Elecraft] New P3 TX Monitor....unusual behavior with SWR (at times)
I find this thread quite interesting. I too have been dealing with VSWR spurts. My TX lineup is similar to Phil's, but I don't have the TX Monitor. After a recent station rewiring job I found I was having a great deal of trouble with indicated VSWR jumping to high levels with the amplifier on. The problem was especially bad on 80 meters -- anything above about 300W would randomly give a high VSWR fault on the KAT500. Since the KPA500 was feeding the suddenly changed load it too would usually fault out. The sensor for my LP-100A is on the antenna side of the KAT500, and its VSWR indication was rock solid during these events. My station is in an extremely difficult RFI environment, with seven antennas crammed onto a 0.2 acre city lot. I immediately suspected that common mode RF was getting into the reverse power sensor circuit in the KAT500. I installed a Balun Designs choke on the antenna side of the LP-100A sensor and the KAT500 stopped giving the high VSWR indications right away. That's the good news. The bad news is that now the KPA500 is doing it, but at considerably higher power levels. I can run around 400W out before the KPA500 begins to randomly show VSWR faults. The KAT500 is completely stable at full power. For now, I'm living with this situation. So I would suggest the troubles you're seeing may be the result of common mode RF problems on the transmitter feedline. It could be that the addition of the extra electrical length of the TX Monitor sensor and its associated cabling changed things just enough to put a common mode voltage node near the KAT500 output port. You might try adding an additional piece of coax somewhere in the lineup and see if that changes the situation. RF is funny stuff. 73...

[Elecraft] New P3 TX Monitor....unusual behavior with SWR (at times)
Does this happy to anyone else with the new TX Monitor…? My TX monitor sensor sits between my KPA500 and the KAT500 and since I have installed it and had it up and running I have had more than my average spurts of high SWR. For example, a key down may cause this spurt but just a moment later the SWR is fine at is usual 1.4:1 or so for this particular antenna. I have only noticed this on 80-meter band and I have my KAT500 fully programmed for each segment and also I run the KAT500 in manual mode. I only see this on CW but that is the only thing I have done since having the TX monitor set up except for one time of saying “test, test, test” into the mic to see the TX SSB waveform. Usually, I don’t have any hassles with high SWR spurts on this antenna with the KAT500 and that is why I am thinking there may be some new kind of interference with the sensor in line like maybe brief periods where the Load side which is input to KAT500 does not look like 50 ohms. Thanks for your comments. 73, phil, K7PEH __ 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] New P3 meters
Have you looked at S Meter Lite Software? http://www.seed-solutions.com/gregordy/Software/SMeterLite.htm I've used it with a 2nd CAT port in microHAM Router, which I use with my microKEYER II. 73, Jim N7US -Original Message- Alan, The only complaint that I have about my K3s is the darn S-meter chicklet display that is basically worthless to me as it does not show small changes in signal strength. I am an antenna phreak and like to experiment and compare antenna options. I am on ten meters and have six yagis at different heights and combinations. 160 has six choices. On six meters I have four yagis in various combinations. (don't ask how many antennas I use on 144 MHz!) With the 6 dB LEDs on the K3, any comparison between antennas is pretty meaningless oftentimes. I found a neat software package that gives me a much more sensitive signal level meter, but it uses the serial port so it interferes with computer logging etc. Anything that will show fine detail in signal strength will be a Godsend for me. I loved my old analog S meter on my Ten Tec rigs. It was so valuable in such mundane things as tracking down power line noise with my very directional 144 MHz antenna. I could locate noise 3 miles away to almost the correct pole just from my shack! With the K3, I have lost that capability entirely as the chicklets do not change unless it sees a huge change in strength. Calling the power company to fix noise is a full time job here. Of course, for casual operating and contesting, the green chicklet display is fine. If Elecraft solves my S-meter problem, I will definitely become a true blue Kool-Aid drinker. Dave K1WHS ps. I have had thought about digging into the K3 rx circuit to install an outboard analog S-meter. I am getting desperate! __ 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

[Elecraft] New P3
I just put together a new P3 and it isn't seeing the rig. It also will not see the computer through the P3 Utility with the serial cable. If I unplug power from the P3, I can see the K3 through the same cable using the K3 Utility (same comport, 4). I am using an Aten usb adapter, but it works fine on the K3 direct or through the P3 with power off. So, I assume its not the cable or the USB adapter. I've tried various combinations of baud rates, but the P3 Utility just keeps attempting to contact the P3 on port COM4 and never connects. Every time I turn on the P3 it says: P3 BOOTLOADER INVALID SAVED STATE DATA USING DEFAULT VALUES CHECKSUM TEST The P3 is reading the IF input and displaying the Spectrum Display and Waterfall Display, but doesn't show frequency (reads 0) and won't tap to QSY. P3 firmware shows to be 01.20 SVGA firmware shows to be 99.99 and I get no video out to my monitor. Thanks for any help!
