I used one port to communicate with the Icom CI-V bus and buffered the DLP-232M's input/output pins with a 7417 Hex Buffer IC as recommended in the ARRL Handbook CI-V Interface design. I made the port's DTR & RTS outputs jumper selectable and used another of the 7417's buffers to drive some 2N3904s, providing a PTT function.Īs there was a second (spare) port available, I interfaced it directly to a Winkey IC.

The Winkey IC (and also the 7417) are powered by +5v from the PC USB Bus, so the keyer is inoperable when the PC is powered off. I had a nice Lansing Instruments case available to house this project, and, as there was plenty of space available in the case, I included yet another simple soundcard interface. The box now provided three functions which reduces the shack clutter. The simple circuitry was built on a homemade PCB. The artwork was hand-drawn directly using a "Dalo" etch-resist pen.

The rear view of the completed project is shown below.Įverything worked first-time as soon as I plugged in the USB cable.Īfter Windows XP detected the new hardware, the FTDI serial port drivers were loaded and the 2 ports installed as COM3 (Winkey) and COM4 (CI-V). I use the CI-V interface with N1MM Logger and Logger32.
The Winkey works fine with N1MM Logger and my own QD Keyer program. When my family bought me a Begali paddle as a birthday present, I started to get some erratic keying of dots from the Winkey. This was a due to varying contact resistance on the paddles affecting the voltage detedtion on the PIC's input. This has been a common issue and Microham sold an inline debouncer to address the problem.I chose N1MM Logger after hearing Tom Wagner's presentation at Boxboro 2002. Having only returned to ham radio in late June after 38 years off the air, I didn't even have a PC when I started thinking about logging and contesting software.
It took a while to read through the very detailed User Manual, but downloading and launching the application is pretty straightforward. I tested it out as a "front end" to my regular logging app (DXbase 2003) for a couple of weeks before the recent CQWW SSB DX contest, and just had to chuckle out loud when I actually got Logger to work my radio and display both VFO's bandmaps filled with spots.

During 30 hours in the contest, the software worked flawlessly and I am sure it was worth at least half my score in my first-ever attempt at competitive radio. The User Group is unbelieveable, support is fast, and from my own 35 years in the high tech data networking field, I don't know of a similar product that has anywhere near the User Benefit-to-Price ratio as N1MM Logger. Hey, it's INFINITE! A great, great product for contest logging.
Let me preface this remark by saying that I'm usually a pretty brutal reviewer, and I'll frequently nitpick the heck out of buggy, bad software from time to time. This is a fully-featured contest logger that integrates rig control, packet and Internet cluster spots, callbook interface and offers dual dynamically-changing band-maps. Just click the packet spot for the station you want to work (the calls in red are the multipliers), hit the spacebar a couple of times and presto. My setup has a Kenwood TS-570D on Com1 and a RIGblaster Plus on Com2, but the program is capable of handling up to 8 serial ports and 3 LPT ports as well.

There is also full support for networked use for those big Multi-Multi stations, but I've never tried to use that functionality so I can't comment on it. Since I'm not a CW operator I can't vouch for the CW keyer built in, however the comments I've read in the Yahoo group are very positive.
