2 HOW YOU ENJOY APRS WITH TH-D72A/E (WRITTEN BY BOB BRUNINGA, WB4APR)
These views show the screens for a station with frequency included in his position packet. This is the
11th station in the list and it is beaconing its operating frequency as well as a short note telling
everyone he is also listening on Voice Alert in simplex range. The "MENU" button on this display will
bring up a number of additional actions. One is the TUNE function shown in the middle display
above. When TUNE is selected, then the radio automatically tunes to the second band frequency as
rd
shown in the 3 display.
Voice Repeaters and Club Info
Besides alerting others to the voice monitoring frequency of other APRS operators, the addition of
the Frequency field to APRS opened up a whole new application of local information for the mobile
operator. Now everywhere the APRS operator travels, he can be alerted to the recommended
travelers voice repeater in any area he was passing through. This is accomplished by not only
having every digipeater beacon its position and availability, but also by beaconing this local frequency
object. These frequency objects show up in the station list of all mobile operators in range as shown
below in the TM-D710A/E and TH-D72A/E front panels:
On the TM-D710A/E station list as above, not only are the two stations of AB9FX nearby, but also his
current VOICE operating frequency is visible. Also, we can see that this radio is in OPERATING
range of three voice repeaters that are also identifying themselves as objects on APRS as the locally
recommended voice operating channels. The TH-D72A/E on the right has two ham calls, two tactical
calls and one repeater object. It is easy to find these nearby frequencies in the huge station list by
first doing a SORT. This brings all the numeric objects (in this case, frequencies) to the top of the list.
But there is more!
The standard for these frequency objects also includes Tone, Shift, and bandwidth for instant tuning.
In addition, they include the weekly on-air voice net times as well as the monthly club meeting dates
as shown below:
