[Elecraft] Would you be interested in a K2 PSK31 digital interface card?
YES! Either board(s) or a kit would be just ducky. Price and availability please.

Re: [Elecraft] Would you be interested in a K2 PSK31 digital interface card?
Bill, I do not believe an interface kit is currently available - a kit with isolation transformers is problematic for the K2/100 because there just is not room inside for transformers. If you want a simple box to switch between soundcard input and microphone, take a look at my website "Switchbox" article www.w3fpr.com - alternately combine that implementation with the digital interface published in QST for July 2010 page 37. You might also want to look at the Fixed Audio Output as well, or the updated version which can be found on Tom Hammond's website - www.n0ss.net. The Fixed Audio Output is simple enough to construct on perfboard and can fit between the front panel and control board. 73, Don W3FPR Wm Bush wrote: > I would like an interface kit. > > New owner of a K2, and new to the list. > > Great Fun. > > Bill > KD8JXJ > > > > > > > - Original Message > From: jperelst > To: elecraft@mailman.qth.net > Sent: Sun, July 11, 2010 8:42:01 AM > Subject: Re: [Elecraft] Would you be interested in a K2 PSK31 digital > interface > card? > > > I just noticed this post.

I'm not done with my K2 yet, but I do a lot of PSK, so I'd like a kit (or board).

Re: [Elecraft] Would you be interested in a K2 PSK31 digital interface card?
> The boards as designed by EA3BLQ did not provide a "line out" audio > signal, That is not correct. The EA3BLQ "Digital Interface" board (K2DI v. 3) provides a buffered/amplified signal from J5 (demodulator output before the volume control). This is the definition of a "line out" signal. While not quite the same as Tom's board (Don's design), the EA3BLQ "K2DI" board is functionally identical on receive and provides for PTT microphone switching/muting that is missing in Don's design. The K2DI board can be used on a stand alone basis if one does not need the "digital mode VOX" (e.g. "tone switching") or transformer input/output isolation provided in the K2DI-PCI daughter board. 73, ...

Guy - The boards as designed by EA3BLQ did not provide a "line out" audio signal, so using one of his boards would not provide the type audio you are seeking. While Tom's (N0SS) board does provide a fixed audio, it also requires that you make solder connections to the Control Board of your K2. If you are comfortable with doing that, then I suggest you ask Tom for his files and have a couple of boards made. Please contact Tom @ N0SS (at) arrl.net for any more discussion about your needs.

Re: [Elecraft] Would you be interested in a K2 PSK31 digital interface card?
I have a particular need which is not a digital interface per se, but need to know if this project addresses it, or if some subset addresses it. This will be used in ongoing rudimentary research on 160m antennas and ground phenomena currently under way. I will need a fixed audio output from the RX which is independent of the AF gain control, which will be fed to a meter reading in dB. We will be taking field measurements on weak signals on small antennas from low level self-contained transmitters fitted with small antennas. I saw N0SS sell off his last remaining fixed audio boards before I realized what they were. I will probably be encouraging some local friends to outfit their K2's in a similar fashion. Also, is the fixed audio board file that N0SS has in a format that can be fed to one of these small quantity PCB companies, or would it need to be converted? 73, Guy.

Re: [Elecraft] Would you be interested in a K2 PSK31 digital interface card?
This is a great effort, and I applaud John for taking up this task. Pauli had a great design, and I know there are many who would like to reproduce it.. Now to relate "the other half of the story" -- when I was offering kits and boards for the W3FPR Fixed Audio Output, I was amazed to find that one day that Pauli ordered one. I quickly sent him an email asking why, since he had developed a great digital interface for the K2, and he replied that my solution was quite simple and elegant by comparison. Yes, the microphone and PTT switching must be done in an external interface box (many do that), but just the addition of a fixed level audio output alone is very helpful to working digital modes with the K2. If you are interested in this more simplified solution, check out either the original design on my website www.w3fpr.com or see the updated board that Tom Hammond N0SS developed which mounts easily between the Front Panel and the Control Board. Tom no longer offers either the kits nor the boards for this design, but he has offered to provide the board layout to anyone interested. See www.n0ss.net for more information. The design is not complex and can easily be implemented on perfboard if you do not want to go the route of ordering a lot of boards (and selling them to others) from FAR circuits or other board sources. 73, Don W3FPR NQ3RP wrote: > I've tried to find one of EA3BLQ's interface cards for the K2 but have not > been successful.

[Elecraft] Would you be interested in a K2 PSK31 digital interface card?
I've tried to find one of EA3BLQ's interface cards for the K2 but have not been successful. So I thought I would design a replacement since I've done PCB designs before. The problem is that if I do it, to keep the cost down, I would have to make a couple of dozen boards. So I wondered if there was any interest out there in obtaining one of his boards.
