Advanced Monitoring of Pages
+ For details on the PAGEMON command, see the Command Reference.
You may wish to monitor pages from another amateur station or from a “county”
emergency or weather watch station from time to time. To monitor, simply type
PAGEMON ON at the command prompt. Pages received and decoded are dis-
played as follows:
PAGER>capcode (function bits state) [date time] message.
For example, if WØXI sent a page to pager 1234568 with the message “CQ CQ
CQ DE WØXI K,” it would appear decoded as:
PAGER>1234568 (3) [date time] CQ CQ CQ DE WØXI K
Two function bits are included within each page message; hence four function
bits states are possible {0,1,2,3}, where the 0 state corresponds to both bits set to
zero, and so on. Normally state 0 denotes a numeric page and normally state 3
(both bits a 1) indicates an alphanumeric page.
The TNC uses these fuction bits to decide how to decode the page, e.g., as nu-
meric or alphanumeric. The TNC sends all numeric pages with a state of 0 and all
alphanumeric pages with a state of 3, as specified in the original POCSAG stan-
dard.
Keep in mind, however, that the county stations and other non-amateur paging
terminals (stations) may not adhere to this standard. They may reassign states for
various page formats, even mixing numeric and alpha pages with the same func-
tion bits state assignment. You may be able to copy these pages anyway if you
make use of the {cccc} feature of the PAGEMON command. Each “c” is as-
signed one of the four letters: N, A, X, or Z, with the following meaning:
•
N defines c as numeric,
•
A defines c as alpha,
•
X defines c as either numeric or alpha, and
•
Z defines c as “don’t monitor this state assignment".
