Referring to "APRS Protocol Reference - APRS Protocol Version 1.0 -
Document Version 1.0.1: 29 August 2000", p.79.
About the APRSH query it says:
:KH2Z_____:?APRSH_N0QBF____
"A query asking for the number of times N0QBF was heard in each of the
last 8 hours. (Note the trailing spaces in the callsign following APRSH,
padding the callsign to 9 characters)."
AND (second paragraph)
"-- this callsign does not need filler spaces as it is at the end of
the data."
which is correct? By the way, I have my doubts about the leading space
too.
The response is:
:N8UR_____:N0QBF_HEARD:_1_3_2_._._4_5_6
What order do the 8 hour data have in the response?
Do the dots mark 0 or "no data" (as in off line)?
In the table page 77 it says that the response should be "Position of
heard station as an APRS Object, plus heard statistics for the last 8
hours". What data (symbol etc.) should this object have? Wouldn't it be
better to fake a digipeat of the heard station?
