Re: [Elecraft] Will the K2 and KX3 work with the P3?
I'm not sure what you are trying to accomplish here with the KX3, pardon if I mis-interpret. Using a P3 requires that two issues be resolved: 1) control and, 2) RF signal input. P3 control is via the serial RS232 connection, and can be figured out. However, the P3 wants to a single RF signal at its IF input. It then goes through a typical DDC-based SDR approach, including an FFT, to display the spectrum. The P3 works with the 8.215MHz IF output of the K3 (or many other RF-frequency range, IF signals). The KX3 does NOT have a single RF/IF output at the proper frequency. Instead, it has an I/Q output pair at audio frequencies (0Hz-approx 48kHz or so) from the internal QSD. You would need to upconvert that I/Q pair back to a single RF signal in order to feed it to the P3. That's a lot of work, with much simpler solutions available. I don't know much about the K2. Looking at the manual, internally, it has an 4.9152MHz IF, but I don't think that's available on a connector, or if the drive level is buffered and adequate. If so, you could use a P3 with a K2 I suppose. The IF would need to be tapped BEFORE the crystal filtering. I do NOT see an IF output connector, and only one transistor buffer between the mixer and the crystal filters. The KX3 I/Q output is set up to feed into a typical computer sound card (stereo, line-in) and a Softrock SDR-type program, which is easier than trying to jerry-rig a P3. You can potentially use a CAT interface with the KX3 to query the current frequency, for SDR software display. I have NOT one this directly, so I don't know what SDR software support that. 73, Terry, WB4JFI -Original Message- From: Tom Sent: Tuesday, August 27, 2013 11:35 PM To: Elecraft Subject: Re: [Elecraft] Will the K2 and KX3 work with the P3?

Re: [Elecraft] Feature request - Disable Break In on K3
Interesting discussion. I use KEY-OUT to control my sequencer so my mic or KEY function just like they do on HF. I utilize INH to prevent RF until the proper time in sequence of change over from Rx to Tx. BUT, I do not do very much CW on VHF+ with my KEY. Most CW is computer "keyboard" generated so the sw generates a RTS command over RS232 to Key the K3 PTT. This is definitely semi break-in, where the radio is held in Tx as long as CW characters are running in the computer buffer. This will be an issue if I send CW manually. Looks to me adding a manual PTT switch which keys PTT on the K3 would be the solution (could be a foot switch or toggle switch on the control panel). I assume I would not need to switch off VOX as the PTT input would overide the VOX. Is that true? I try to configure my station to work nearly automatically when I change over from HF to VHF+ so mistakes do not happen. Thanks to the originator of this quesion. 73, Ed - KL7UW http://www.kl7uw.com dubus...@gmail.com "Kits made by KL7UW" __ 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] Feature request - Disable Break In on K3
Mike, I cannot remember all the details in the original discussions, but I am "with you".. I was outvoted. OTOH, if one is using KEYOUT to initiate the sequencer, if KEYOUT does not become active until PTT is asserted, then there is a "cause and effect" problem - the sequencer will not start until PTT is asserted (because it is started with the KEYOUT signal) and further delays (requiring the use of TX INH) will be introduced. The solution is to start the sequencer with the onset of PTT (from the PTT footswitch or other switch) rather than using the K3 KEYOUT, and use TX INH to inhibit RF until the sequencer completes its cycle. That solution eliminates the "chattering relays" situation, and does not cause other problems. 73, Don W3FPR On 8/27/2013 6:52 PM, Mike Harris wrote: It would be interesting to learn under what practical circumstances someone might offer that the current arrangement is a desired mode.

Re: [Elecraft] Feature request - Disable Break In on K3
Hi Mike, if You open some mail-archive You can see a lot of mails concerning this behaviour (recognized as strange by some of us) from the first days of K3. There is probably no way for solution. So if You have key activated You have a Key Out activated. There is no real PTT out. Probably this was not recognized in design period as a real need and nobody count with some of us with more complex systems with VHF/UHF transvertors, premplifiers and a lot of relays around :-( Yes, there is no RF and You have Inhibit port.

Re: [Elecraft] Feature request - Disable Break In on K3
Iain, That operation was tossed about at great length during the early K3 Firmware Field Test. I forget all the details, but the current operation was the consensus at the time. If one is using a sequencer with an external input into the K3 PTT, the sequencer should start activation with the PTT switch, not Keyout. Changing his sequencer input should resolve the problem, although he may want to use TX INH in additon to allow RF only when the sequencer has finished. That solution allows normal QSK on HF and protection when using transverters and/or preamps that must be protected on VHF/UHF. 73, Don W3FPR On 8/27/2013 6:19 PM, iain macdonnell - N6ML wrote: It does seem a bit lame that KEY OUT is activated when the K3 is not transmitting.

Re: [Elecraft] Feature request - Disable Break In on K3
"Are you saying that with VOX off, and no external source of PTT, your K3 is going into transmit when you operate your key? i.e. you see the red TX LED light? " Yes to the first, no to the second. To explain - in CW mode the K3 sends a PTT signal on the keying line whenever the key is down. It does not matter if it is a straight key or the memory, the PTT output is still active in sync with the sidetone. The radio does not transmit but that's hardly an issue in my case as its only putting out 1mW at ~28MHz. The problem is the PTT signal when moving rapidly causes a lot of relay chattering and bias supply switching, I have not tried it with my 24GHz which uses a rotating waveguide switch, but I am sure it wouldn't be good for it. In VOX mode with QSK I could understand this hapening, but when VOX is off, you wouldn't expect the key to activate the PTT signal. A way around that is to have a VOX hang, but that appears only to work on SSB. -- View this message in context: http://elecraft.365791.n2.nabble.com/Feature-request-Disable-Break-In-on-K3-tp7578303p7578315.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

While I agree with your analysis that the problem was a bad shield connection to a crummy cable, there's a bit more to understanding what's going on. Coax (and other transmission lines) reject noise and crosstalk by providing a low impedance, low reactance path for return current. That is, the current in the center conductor returns in the shield, so the total field outside the coax is zero, and no external field can couple into the transmission line. When that return connection is not there, the current returns by whatever path mother nature finds, a large magnetic field is generated that is proportional to the loop area, and any RF current near that loop is coupled into the circuit. Yes, one solution is to buy a decent cable. Another is to take a short piece of RG58 (or any coax with a copper braid shield -- the cable is far too short for Zo to matter) and put BNC connectors on each end. If you have a decent crimper for BNCs and some connectors, that's easy. If you don't, it's a bit more work. :) 73, Jim K9YC __ 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] Value of K2 field test unit
Jim, If a Field Test K2 is upgraded with all the A to B mods, new firmware and the IF filter crystals upgraded, its performance will be equal to those kits currently being shipped. The parts for that kind of full upgrade will be in the vicinity of $125, so you need to downgrade the price from a new one by at least that much. If you also consider that the buyer may want to have someone else do the upgrade work, the labor will likely be in the $150 to $200 range, so that might be taken into consideration as well in arriving at your proposed selling price. Note that upgrades are not the same thing as the options - some owners confuse the two. An early K2 will still perform well even if not upgraded, but I believe the price of the upgrades will be taken into consideration by any potential buyer. If you have installed any of the upgrades, that is a plus in your favor in your pricing - specify the upgrades that have been installed. Most recent K2s (SN over 4660 have all upgrades installed) that I have seen offered for sale are priced at 66% to 75% of the new kit (plus options) value. 73, Don W3FPR On 8/27/2013 7:13 AM, Jim Apple wrote: I'm about to put serial number 0069 up for sale but I'm having a hard time getting a sense of a fair value for it.

Hisashi, I'd like to know if you experience the dropped characters on receive, or during transmit? You show it as a RTTY decode question, but is that specific? Read my previous post carefully. I am also describing a similar thing during transmit. Paul has been working on it. I'd like to see this get fixed. I'm sure if everyone using a keyboard will report their experience, we can establish if it is a hardware problem for a few, or something common to all.

So far I've found that the SVGA bias needs to be turned way down from the default of 9.9 to 1.2-1.5, and that I'm losing simple serial data from the K3 to the P3 SVGA on receive. I think this is a serial line problem and Gary from Elecraft suggests turning down the rate from 38400. Also, the USB keyboard I have (a Cooler Master I just got) doesn't appear to work and I'm sure it's another problem on my side. Everything else has been.

If during receive, that would be a new problem.

Re: [Elecraft] P3 SVGA RTTY decode question
Paul, I think Hisashi is describing while using RTTY what I have been talking about while using CW with a keyboard when I said that some characters (not elements of the characters) are being lost during transmission. They show on the monitor, but not on the K3 and are not being sent. (I'm saying this for Hisashi's benefit so that we are in sync.) Hisashi, at this point, I'm wondering if you are seeing this while transmitting as I do? or do you see it during receive? If during receive, that would be a new problem.

Re: [Elecraft] P3 Spurii and a cure.
Huh, I just noticed I have them too. So, given that regular cables don't always remove these, how does one build a mil-spec bnc cable?

Re: [Elecraft] P3 SVGA RTTY decode question
Hello Hisashi, The P3/SVGA terminal mode which allows you to display decoded CW/RTTY/PSK31 text on an external monitor uses the decoder built in to the K3. If you are missing characters on the SVGA display, first make sure that the K3 is correctly configured to decode the correct mode. Another common problem is when the K3 utility is connected along with the P3/SVGA. You cannot have both operating at the same time. 73, Paul -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-SVGA-RTTY-decode-question-tp7578289p7578293.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
Re: [Elecraft] P3 SVGA RTTY decode question
Hi Hisashi, The P3/SVGA board is acting as a terminal. It does not do any decoding. It just displays the decoding done by the K3. If you're missing characters you may want to adjust the threshold on the K3.

Re: [Elecraft] P3 Spurii and a cure.
Regarding the hump monster appearing on the screen of the P3: I had this to a severe degree with my P3 when I first put it into service. Here are the results of my quick tests: 1. humps vanish when the P3 has no patch cord attached to it. 2. using a different BNC patch cord from the P3 to the K3 caused the humps to vary in intensity: a. using a 20 year old mil-spec BNC patch cord removed the humps completely. b. using a replacement from Elecraft improved the situation with smaller humps. c. using a different replacement from Elecraft also reduced the humps. As a result of the above, I use my 20 year old mil-spec BNC patch cord and am very happy. Not a big deal to me, it was easily fixed, and I am very happy with my P3.

[Elecraft] Value of K2 field test unit
I'm about to put serial number 0069 up for sale but I'm having a hard time getting a sense of a fair value for it. It has the auto tuner and battery, but is has not been used in 6 years so the battery probably needs replaced, no ssb module. And I have an unbuilt DSP option that will go with it,.
