Convert a KXUSBa cable to KUSB
Locked
 
|
Somehow in the entropy of the universe and my cluttered shack/shop,
I have managed to lose my KUSB cable for my K3. I found the earlier (silver) cable, but it doesn't have the FTDI chip and won't work with Win-10. In the process of searching for the KUSB I have managed to unearth two KXUSBa cables for my KX3. Since I don't need two KXUSB cables, I am contemplating cutting off the mini phone plug and wiring up a DB-15. Has anyone done this? And, anyone see a downside? Thanks es 73 Bill N4LG ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Bill,
I haven't looked into the electronic validity of what you are asking but I would recommend building an adapter with a female jack and DB-15 vs cutting off a working connector.

A DB15 is not going to connect to the DE 9 on the back of the radio. A DB15 is a much larger connector.
Also, converting the KXUSB to use on a K3 is not going to provide all the signals that the KUSB has. No RTS/DTR.

I don't know these cables but I would like to add a caution. Some Elecraft "RS-232" interfaces are true RS-232 (voltage swings greater than +/- 8 volts) and others are TTL (voltage swings between 0 V and 5 V). Be sure you know what you are connecting to what. Some of the receivers are designed to accept either TTL or true RS-232 but perhaps not all of them are. Driving true RS-232 into a TTL receiver may let the smoke out.
I'd suggest reviewing the schematics before cutting and splicing.
