Somewhere around here I've got one of its ancestors, a PCB-88. That's a PK-88 on a full length ISA board to mount inside the computer. I've also got a HAL P-38 HF modem. Similar form factor, does

I want to know how I can use Kenwood 710 for aprs if you can guide me

And a Radio Shack power supply. That's sooooo last century. Patrick (N3TSZ)

One doesn't see the AEA, now Timewave, products get much acknowledgment. That -900 is ca early 90's. Even the APRS To-call doesn't list the manufacturer's product, past or present.

Wow nice. I never saw one of those before.

Just thought I would share to the group which vintage TNC I'm using.

Bob, Understood. 73 Randy KA0AZS

The PHG circles are drawn at HALF the calculated range to account for about 6 dB of mobile loss due to flutter, etc. Most programs also allow you to draw then full size which might work for some fixed

James, Roger that. I am aware of the differences between AGL, MSL and HAAT. The heights were given to me by the Trustee. Since one of the numbers does not match where I know the antenna is AGL, I'm

Bob, RR. The link that Fred posted (to a page I think you wrote) refreshed my memory and explained it perfectly. 73 Randy KA0AZS

Fred, Thanks! That explains it all perfectly. I think I knew that at one time but have not set up a PHG in so long I had forgotten it. 73 Randy KA0AZS

Also this height is not altitude above sea level. It should match your height above average terrain (HAAT). Also if your coverage is offset somewhat by local terrain, you might want to report a

There is only 1 digit for height. So it uses powers of two.. Just pick the closest one. Bob, WB4APR

Hi Randy, Read this: http://www.aprs.org/aprsdos-pix/phg.txt I think you will find that your absolute heights, power, etc., may not be in the spec. You need to pick the closest. Fred N7FMH

I'm setting up objects for a couple of local Winlink nodes. Winlink inputs them to the IS stream, but I wanted them to be available locally on RF.  Transmitting objects is simpler than attempting to

I have had APRSIS#@ running for years on my station computer. Well I go a new computer and reloaded many old programs back onto the new one. I can't remember how to add the shape files or where to get

Idon't want to make this too confusing, but a single instance of Direwolf does not allow 2 separate ports. However the Nexus DR-X implementation on the Raspberry Pi allows for separating the 2 audio
