It worked well but I had to change a few things of the DSP code. Later I replaced my desktop PC and the Windows versions changed too. Recently I tried to compile the program for Windows 10 with Visual Basic net 2013. Few things gave compiling errors and I overworked the app. Now, there are no more changes to the DSP code necessary and by far not complete, the app may be of some interest to others. Many hours of coding are spent, but I learned a lot for other Windows applications, so the time was not wasted. The state of the application is now such, that I decided to share my work with other interested hams. For this I have to clarify a few things: Important for fast PTT! With VB.net it is not so easy to detect the state of the RI (Ring indicator) signal of the RS232 port. So I decided to use the CD (Carrier detected) Pin. You may wire this in parallel with the RI, without affecting the function. Just make sure, that you are not creating a short. My desktop has a real RS232 port. I have the DSP code installed on EPROM, so the EZ-lite is starting directly the DSP10. No Monitor. Be patient, it takes about 4 seconds to start up. There is not much help for using the app available. To the experienced DSP-10 user much should be self-explaining. Most entries from keyboard must be terminated with the enter key to become effective. No file has to be edited with any other editor to change the users parameters. The different opening forms allow this. Some new settings are taken by closing the setup forms, some must be written by pressing save. When you change from one mode to the other, be prepared that not everything is set as you wish, or you had. Don't change to much at short times. The DSP may stall if you do so. Especially when you are transmitting CW, be careful. When you are transmitting most settings may be changed on the fly. How this behaves on air, I do not know. Some of the newer stuff is not implemented, like tuning to fractions of HZ and so on. The RS232 communication is using its own thread. The app is consuming about 2% of CPU power. (Desktop PC from 2011). The compiled setup files are in the setup.zip http://ssvlauacher.ch\dsp10\HB9OMQ.htm The source code is also available to the interested.

A few days ago I was cleaning out a closet and found a complete DSP-10 kit including the DSPx digital board and KDSP10 interface board. This is enough to build up a complete working unit from 2 meters to RS-232. I have my first DSP-10 here, still working, and use it from time to time to make noise and frequency measurements. These are not Heathkits. DSP-10 requires some experience and savvy to get working, but all the parts are in the box. If anyone would like to take this kit off my hands, I'm asking $250. Or, make an offer. Reply here. 73, Courtney N5BF
