Re: How to edit or delete PHG from

Lynn Deffenbaugh

I should have also mentioned that when doing the PHG0000 from a radio, you need to transmit the beacon containing the text in range of an IGate to get it through the APRS-IS to  Checking the raw packets of the station that transmitted the packet should be sufficient to ensure that at least one has been delivered.'s Decoded view is also quite informative to ensure that it interpreted your intent correctly.

It appears that you actually DID get the PHG0000 entered into a radio correctly, but's parser didn't parse it.

But when you did it from APRSIS32, it got the PHG extracted correctly.

So it seems that where the radio put the comment caused's parser to see a leading ` which caused it to not "see" the PHG0000 for what it was intended to be.

PS.  In the future, please state exactly callsign-SSIDs when asking for help.  It took me a while to translate "one of my generic SSID" to W3KIT with no (actually -0) SSID to find the actual station you were trying to fix.

Different radios call it different things, and unfortunately I believe some radios call the Mic-E "status" field their "comment".

But I believe that every APRS-capable radio has somewhere that you can enter free-form text to be included with your position beacon and that's exactly where the PGH00000 would have gone to clear out's memory.

There is nothing "special" about APRSIS32's "comment" text, it's all in the label given.

I don't have any Yaesu APRS radios, but in my Kenwood D74, there's a "Position Comment" (menu 502) which is NOT it (that's the Mic-E select-a-status from a list including things like Enroute, In Service, Returning, and so forth) and "Status Text" (Menu 503) which is where you can pre-configure up to 5 different free-form texts and select one to be included on beacons.

PS.  It looks like Yaesu does something similar to the D74.  I've attached 3 pages from the Yaesu APRS manual where it describes the required free-form comment text.

What is the different between APRSIS32 "comment" text comparing to another radios with beacon status or comment text?   I have tried to rid of an unwanted PHG by using the radios (FT2D, FT3D, FTM-100 and FTM-400 - I could not find the way to enter PHG0000 to clear it.

I have to fired up APRSIS32 and edited the SSID to the SSID that I want to clear the PHG and that was the only way that worked.

Is the "comment" field a special field that ordinary APRS radio does not have and only existed with APRSIS32?
