Introduction
The full name of APRS is Automatic Packet Reporting System. More than
10 years ago, there was the APRS in China’s domestic market, but it was
expensive and hard to use because of its poor integration so that it was not
popular at that time. BI7NOR ＆ BG6QBV designed and produced the low
price AVRTx serious special device, which help more HAM radio ameture to enjoy
the fun of APRS by lower cost and simpler operation.
The modification and improvement has been done to AVRT7 Plus by
combining old model’s advantage and users’feedback. AVRT7 Plus can achieve
the APRS iGate (rate : 1200bps). It compatible the regular amaturish and
commercial APRS device and many kinds of APRS Digi repeater station and
iGate， and it is the first network iGate multifunctional APRS device in China‘s
domestic market that with the internal radio module and individual 2-channel ’
s real-time decoder and it can upload the data to the network server in the
meanwhile.

The major function of AVRT7 Plus is to achive the APRS iGate (rate 1200bps) with the full
programme including VHF receiving module and 2 individual TNC Codec. It works (with the
right data setting) when the network cable is plugged in and the WIFI account and password
is set up. It compatible the regular amaturish and commercial APRS device and many kinds
of APRS Digi repeater station and iGate.
1. With the internal RF + extension radio it can achive the 2 channel real-time decoding : with
internal RF receiving module, and with the extension radio socket, the data could be
uploaded to the server while decoding to achive the real-time APRS iGate network gateway
function;
2. With the optional LCD screen : the user can see the real-time data received without cell
phone, computer or Garmin navigator ;
3. With the optional BPM180,18B20, the extension meteorological function could be
activated : ( the new function module could be ordered such as tempreture, humidity, wind
direction or speed, etc. )

※ two channels real-time dual decodding diagram:
In this mode : AVRT7 plus could decode the beacon from VHF module inside and from extension
radio at the same time, and AVRT7 plus would upload the valid beacon to the APRS-IS server
without mutual interference.
So the V+V and the V+U dual frequency gateway could be easily established to achieve the
function of dual standing by and dual communication.
