What is APRS digipeater?
“Digipeater” is short for “Digital Repeater”; a repeater for packet data rather than voice. Unlike the standard voice repeater that receives on one frequency and retransmits what it hears simultaneously on another frequency, the usual digipeater is a single frequency device.
What is APRS IGate?
An IGate (Internet Gateway) has two functions: to pass all packets heard on RF to APRS-IS and to pass all message packets destined for local stations to RF (if a bidirectional IGate). The first part of this is sometimes misunderstood. Generic queries are APRS query packets that are not directed to a single station.
What is the APRS frequency?
144.390 MHz
The HX1 is a low-power amateur radio transmitter set to a fixed frequency of 144.390 MHz. In North America, this frequency is used for the Automatic Packet Reporting System, or APRS. APRS is a standard used by amateur-radio operators to broadcast live sensor data on a shared frequency.
What is APRS ham radio?
Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time digital communications of information of immediate value in the local area. Data can include object Global Positioning System (GPS) coordinates, weather station telemetry, text messages, announcements, queries, and other telemetry.
How do you find a digipeater?
As u/VA7EEX and u/molo1134 said (between the two of them), go out to aprs.fi and pop in the callsign/alias for the digipeater. Click on ‘raw’ in the upper navbar and you will see the status packets that are beaconed every 30-60 mins. You should be able to figure it out from that.
How does an IGate work?
IGates, on the other hand, are a different story. When an IGate, or Internet Gateway, hears traffic, it sends that data to the APRS-IS (Automatic Packet Reporting System – Internet Service). APRS-IS is a live stream of APRS traffic worldwide. Without APRS-IS, websites like APRS.fi would not be possible.
Do I need to register for APRS?
Registering with the website is only necessary if you want to use the web management tools to configure your aliases, shortcuts and view your profile. There are a few things that need to be done before you can register to use the web tools.
How does a digipeater work?
The digipeater listens for data chirps that have been encoded with instructions to retransmit them and then retransmits what it hears when appropriate. This allows users with mobile or portable APRS stations to cover a wider geographic area.
What do you consider a success with a digipeater?
I’d call that a success. The fill in digipeater is something you don’t want to use all the time as too many fill ins can degrade the APRS network. But if you are doing an event and want to use APRS, these fill in can provide extra coverage for weak areas, especially if you are using low powered trackers.
What is an APRS digipeater and do I need one?
While APRS can be used to keyboard back and forth much like instant messenger, it’s most popular use is showing the position of moving objects. In order for this whole network to work, it requires users with the proper gear and digipeaters. A digipeater is a digital repeater.
How many amps a day does a digipeater draw?
That’s 24 amps a day. Now either wait for radio to transmit or push the transmit button if you can and read the current draw. This is an intermittent draw that will vary drastically depending on how often your digipeater ID’s or how much traffic its digipeating.
