Re: [digitalradio] An experiment: APRS on Yahoo maps

Hi Joe, It works well but I think the satellite pictures are from the stone age, at least around here. Darrel, VE7CUS On 12-Feb-08, at 11:08 AM, Joe Veldhuis wrote: http://www.electroblog.com/radio/yahooaprs/index.php Something I've been working on on-and-off for awhile. There are at le

[digitalradio] An experiment: APRS on Yahoo maps

http://www.electroblog.com/radio/yahooaprs/index.php Something I've been working on on-and-off for awhile. There are at least a dozen web apps out there that plot APRS data on Google maps, but in many areas (including all of Ottawa and Allegan counties in Michigan) there is no high-resolution a

Re: [digitalradio] Re: Operating FSK RTTY in a contest ?

MultiPSK can do 850Hz shift RTTY and add a CR at 72 chars if anyone feels like recreating the old days! maybe there's someone still with a mechanical RTTY machine who will let some of us younger guys experience a QSO... I'm up for it but it would have to be 30m (only decent antenna I got right

Re: [digitalradio] Re: RTTY Standard

I know the AEA PK-232 used 200 Hz, as well as the Heathkit HK-232, but the Kantronics KAM series all used 170 Hz shift. That was the reason I switched from the AEA to the KAM products. What Kantronics models used 200 Hz shift? 73 de Bob - KØRC in MN - Original Message - From: Jos

Re: [digitalradio] Re: RTTY Standard

Kantronics and AEA too. I have a Communications Quarterly issue from the mid 90's somewhere here in which the author modifies its filters for 170 Hz and describes a great improvement for AMTOR...but also becomes almost useless for 300 baud packet. AM7910 modems have 200 Hz shift. Jose, CO2JA

PD Modes The PD modes were developed jointly by Don Rotier and Paul Turner. Although they're a little complicated, they represent a fair trade-off between color accuracy and transmission time. VIS CODES PD50 93d (decimal) PD90 99d PD120 95d PD160 98d PD180 96d PD240 97d PD290 94d COLOR MODE Y, R-
