[Elecraft] K2/Writelog computer interface

2005-05-11 Thread Andy Bullington
Although not a big contester as a rule, last weekend I had a lot of fun working the New England QSO Party using Writelog. I was working mostly CW and doing most everything manually. It was pointed out to me I should be using a lot of the automatic message features in Writelog. This is fine with

That's silly! Modern computers are WAY more capable than that. Someone in charge of one of these keying programs needs to look into the Win-32 API for starting threads with differing priorities. I'm not one of those programmers, but I KNOW you can make the opsys dispatch you often enough, if

Guys, Jim is correct. A PC running windows and most contest/ham programs will key the K2 (or any other CW-capable rig) very nicely. But only if the computer is fast enough to handle all its tasks AND the CW functions as well. Don't expect an old slow Pentium 3 system to handle it very

Not true... I run Writelog with MMTTY which is a RTTY plug in with rig control and it works just fine on an 800 MHz CPU. I also have used it running CW transmit, CW decode (with the sound card), packet screen, rig control, (FT-1000MP) and rotor control with NO PROBLEMS. I use a home brew

Okay, so is it really time to upgrade my from my C64? Just kidding. I meant to mention that the keying issue I noted was during a contest in October and/or November using my work laptop, which is a P4-1000 to key my big rig. The test last night was with my desktop which was running a P3-550,

Okay, so is it really time to upgrade my from my C64? Just kidding. Actually, if you had a C64 your timing problems would be solved. I wrote a CW send/receive program for Atari back in the 80's and it worked great. (6502 processor, same as your Commodore 64.) The problem (if it exists --
