Re: [Elecraft] WHICH USB ADAPTER TO STEREO PLUG TO USE
Hi Greg, The adapter you're hoping to find would need to have a USB *jack*, talk to a USB serial device (the KXUSB-A) you've plugged in, convert that serial data *back* to RS232, and wire it to an audio jack or plug with the correct pinout for your rig interface. What you'll *find* if you look for USB to stereo adapters would have a USB *plug* (or device-side jack), present as an *audio* device to a USB host (computer), convert digital audio to analog, and wire it to an audio jack for headphones or speakers. Unfortunately this won't work at all -- they've got totally different genders of connector, directions of data flow, and types of signals, and data flow. I'd suggest taking USB out of the picture entirely, and keeping it as RS232: Grab a regular DB9-DB9 serial cable, from Elecraft if they use a nonstandard pinout, or from anywhere if they use a standard one. Grab DB9 and 3.5mm audio connectors of the right sex to plug into your serial cable and your rig interface. Find some wire of a sturdy gauge, check the pinout for your rig interface, and solder yourself an adapter. I don't have any *good* advice on holding it together, but my instinct would be either heat shrink around the whole thing or a tiny project box with the DB9 and an audio jack (instead of the plug) mounted. You might also be able to use Elecraft's RS232 to 3.5mm cable, but you'd need to check the pinout against your rig interface -- as far as I know there's no standard for routing RS232 through an audio jack.

Re: [Elecraft] WHICH USB ADAPTER TO STEREO PLUG TO USE
Sorry about the confusing post. I essentially did what you suggested except in the reverse way. I took a good DB-9 cable (RS-232 type) and cut off the other end and soldered the wires to a 3.5 mm audio plug. The wires are so small that they easily break and I have repaired it twice. So I thought I could just make the equivalent of the E850483 cable by using the DB9 to USB cable (KXUSB-A) and then getting a USB to Stereo adapter (Female USB to Male 3.5 mm plug). And that is where I ran into the problem of different USB to stereo plug adapter capabilities. Is there another supplier of a cable that matches the E8500483 or can you recommend an appropriate USB to Stereo plug adapter? 73’s, Greg N9GB From: Jim Rhodes Reply-To: Date: Friday, July 1, 2022 at 10:44 AM To: greg best Cc: Subject: Re: [Elecraft] WHICH USB ADAPTER TO STEREO PLUG TO USE I am not familiar with the Station Master. Your post is kind of confusing. You talk about USB to DB9 and USB to 3.5 mm cables, The Elecraft DB9 to 3.5 mm cable is an RS232 cable used with the KX line and other small RS232 devices. It is still listed on their "Quick Order" page, down near the very bottom. Search for "KXSER-A ADDITIONAL RS232 COMMUNICATION CABLE WITH 9-PIN CONNECTOR" on the quick order page. Like all their cables it is not the cheapest cable you will find, but they are high quality, durable products. Have a few of them around for my KX3, W1, XG3, etc. The DB9 is a female and I believe the K3 has a female connector (I have the USB board in mine) so this may not be the cable you are looking for. You might be better off taking a good quality 3.5 mm cable, cutting the thing in two and soldering on a good DB9 male. __ 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] WHICH USB ADAPTER TO STEREO PLUG TO USE
I had a homemade cable with a 3.5 mm plug on one end which goes to the CAT connection on my stationmaster and a male DB 9 for the RS232 connection for my K3. (I do not have a USB port on my K3). The cable was not reliable, it broke, is now too short, and I was going to replace it with the Elecraft cable made for those connections. It is no longer available and suggested to be replaced by the male DB9 on one end and the male USB on the other end. So I thought I would merely have to get a USB to 3.5 mm stereo plug adapter to add to the DB9 to USB cable. However, there are different versions of USB to 3.5 mm plug adapters. Some that only charge power, some that include MP3 decoders, and some that appear to be for automotive uses only. Has anyone else found a suitable replacement for the cable? Or has anyone else used one of the USB to 3.5 mm adapters and if so, which type and where was it found. 73’s, Greg N9GB __ 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
