[Elecraft] P3 SVGA RTTY decode question
I was copying RTTY on my P3 SVGA and I found that it was dropping a lot of characters. I finally figured out how to decode directly on the K3 and it wasn't dropping characters at all. Is there something I have set up incorrectly?

Re: [Elecraft] P3 Spurii and a cure.
Perhaps it was for the SVGA adapter, but I remember instructions to secure the cable closely along side the cabinet to prevent a problem of interference/radiation. Dick, n0ce - Original Message - From: Roger Crofts To: elecraft reflector Sent: Monday, August 26, 2013 5:57 PM Subject: [Elecraft] P3 Spurii and a cure. I have had 2 problems with my P3 Panadapter, both were the subject of comment on the Reflector. The first was spurii radiated from the P3 DC cord and picked by my nearby antenna on 144 MHz. This problem was largely solved by fitting a commercial RFI filter in the DC cord and ensuring that all panels were clear of paint in the corners where the connections are made. The second problem was the occurrence of wideband noise humps which drift across the display from time to time obliterating the genuine signals. I dubbed the characteristic doubled-humped noise signature as my noise monster. Experiment showed that these spurii and noise products were being generated in the P3 itself. It was not possible to precisely pin-point the source of these signals inside the P3 using a small pick-up loop. The signals were strong everywhere inside the P3 box, but, perhaps, were strongest near the processor chips. This would seem to make sense, but not everyone has these problems, so clearly the mechanism for producing this hash, varies from chip to chip. Thanks to everyone who responded. I am now able to report I have found a complete cure for these problems which works in my case, but, of course, I can not guarantee it will work in every similar case. The cure involves the use of conductive foam. This is the black foam that ICs are normally pushed into when they are delivered. It is carbon impregnated. You can tell the difference between this conductive foam and ordinary foam using an ohmmeter. Pressing the probes against the conductive foam will give a reading of a few Kohms. Ordinary foam will be open circuit. This foam is available from many electronic suppliers. I bought my foam from Farnell Electronics (Now called Element 14 in Australia), order code 168-7846. The cost is 89 cents for a sheet about the size of the P3 side panel. I cut the foam to form compartments to completely isolate the front panel, IF input board, and IO board. I even put foam between the folds of the ribbon cable. In doing this I was carefully not to allow the foam to actually touch any components or bare wires, otherwise a circuit would be formed. I cut the foam panels deliberately oversize vertically, so that when the lid was screwed down, th er e was pressure to make sure the foam had a conduction path to ground. The result of this work was that all spurii have disappeared and my noise monster has never shown its face again. My theory is that the foam is effective because it actually absorbs the RF signals and turns them harmlessly into minute amounts of heat. The problem with metal screening and chokes/capacitors is that these devices simply reflex the RF back. But back to where? The whole P3 box is already abuzz with these signals and they will try to get out anyway they can. The foam kills them dead. That's my theory anyway. If you have these or similar problems, give it a go. 73 Roger, VK4YB __ 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 __ 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] Use MMTTY with K3/0 to K3
Hi Steve, The K3/0 accepts a standard stereo 1/8" (3.5mm) plug for both the line in and the line out. The computer is probably the same for it's line out but could be a mono plug for it's line in (or mic in). He'll have to investigate his computer. He can likely purchase what he needs at Radio Shack but these cables would be much cheaper with greater variety on-line from places like: http://www.cablewholesale.com/index.php http://www.monoprice.com/ http://www.amazon.com 73, Mike K2MK Steven Bertsch wrote > My friend wants to use MMTTY with his K3/0 remoting to my K3.

Moments ago Don (W3FPR) wrote ... ... you might try re-flowing the solder on the Front Panel board with a hot iron (750 degF) and add just a touch of solder - actually all you need is the flux. -- Vern, Just to emphasize what Don means, you should NEVER REHEAT/REFLOW A SOLDER JOINT WITHOUT ADDING SOME "FRESH" FLUX as this will result in a very poor and very unreliable solder joint. And a flux pen is a better source than using additional solder, because you don't want too much solder. Yes, solder can be used as a source of "fresh" flux in a pinch -- in the absence of a flux pen -- but you might first want to remove some of the existing solder. Elaborating a bit further, a blob of solder on the tip of your iron isn't a solution, as the flux would have already burned off by that point. Instead, Don is suggesting that the solder would need to be feed directly into the joint once it's hot. If you have to resort to reheating every joint on the Front Panel, then I suggest a flux pen (or other similar flux dispenser) is a must! 73, Gary KI4GGX __ 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] K-2 observation
Vern, The display has no relationship to any band. My guess is that there is a bad solder connection on the front panel - unfortunately, it is intermittent and that makes it difficult to fine. If it happens again, you might try re-flowing the solder on the Front Panel board with a hot iron (750 degF) and add just a touch of solder - actually all you need is the flux. 73, Don W3FPR On 8/26/2013 1:04 PM, Vern%2C AA7VW%40comcast.net wrote: The other day I was operating my K-2 at about 10 watts on 20 meters.
