The local 2M packet channel was quite alive with activity during the

entire weekend. But, all that was happening on my setup was that the

monitor screen would display about 1% or less of the "connects" that my

ears were hearing, and that was only after I finally used a DOS

command to make sure that the serial port indeed was set to 1200 baud.

Furthermore, every time I tried a "practice" connect using a dummy load,

the PTT line would "hang", and I would have to exit the program to shut

off the transmitter! And, I could not hear any "packet-racket" from my rig

on a separate monitor receiver whenever I did try the practice connects

or beacons. I just heard a single tone 'til I would use Alt-X to end the

program.

Of course, I figured there was something wrong with the program...or

perhaps the modem was only partially working. After all, I was using my

best 386SX PC, etc, etc. I had to decide that I could no longer afford to

tie up that computer with my failing packet test. Had to get back to "real"

work.

And THAT'S when it improved dramatically. As soon as I hooked the

modem to a very simple laptop PC, the transmit and PTT functions

worked perfectly. So much for the 386SX! (Now what was that I was

reading in the Baycom.DOC file about making sure the serial port's

"interrupt" is correctly jumpered? Or did another "resident" program get

there first?)

So, I started sending "practice packets" to my own callsign and was very

thrilled by it for almost a whole minute! Still, nothing much happened on

the screen whenever I was hearing all that local packet noise in the

speaker. The twin "high-low" LED's of the P-IBM modem danced

teasingly in 1200 baud step with those nasty bursts I was hearing for the

umpteenth time.

Now what? I re-read the British/German Baycom.DOC for the umpteenth

time. I resisted my author's perogitive of phoning up on the weekend to a

guy at Ramsey who really knows his packet stuff. In desperation, I

swapped transceivers, easy to do since I had two identical Ramsey FX-

146s.

WOW! The local packet folks were busy at the moment, and my laptop's

screen exploded into Christmas messages for everybody in our country,

news of upcoming DXpeditions, and a veritable flurry of worldwide

callsigns, from locals to VE4,KL7,UW3,VK2 and more...almost ALL AT
