Re: Weather Station Feeding APRS
开云体育These sorts of consumer products are revised frequently, so I don't expect the exact model I have (01525-A1) is still available.? I got it new some 7 years ago.? That said, the software support also changes rapidly, so the best thing is to try and find a match between what's supported and what's available.?Good luck! Greg? KO6TH DavidC KD4E wrote:

APRS Ringer working?!
Harald Rester
Hi,
I can?t get the aprs ringer working. Only the pop ups seems to work. Already double checked the menus and aprs handbook. Did somebody actually ever heard a ringing while receiving a aprs packet (I did not find any yt videos hearing the ringer...)? Any hints would be very appreciated. vy 73, Harry - DH1NBE |

Re: Weather Station Feeding APRS
When I looked a while back the stations friendly to Linux, and that had direct feeds to a local computer, were either off the market or very expensive.
Is the Accurite you're using still on the market? If not, are you aware of a weather station (wind speed & direction, rainfall, barometric pressure) that is. I don't want anything that requires the Internet or a subscription or an app. Thanks, David KD4E |

Re: Weather Station Feeding APRS
Check out the stations supported by WeeWx.? I use it with a weather station from AcuRite, but there are many others.? WeeWx talks to the weather station, depositing the readings in a text file wxnow.txt. The APRS package YAAC runs on the Pi (it's a Java app), reads the wxnow.txt file and can generate the beacons and/or feed to the APRS IS.

The WeeWx package can also feed the weather info to other places (though I have not done that), and it generates an internal web page where you can aim your browser to see all the stats and trends.

Re: Raspberry pi & TNC-Pi9k running aprx
I'm not Lorin.?
For what it's worth, I chose APRX.? I wanted a fill-in digi and a 2-way Igate that would not cause havoc on the channel and APRX's viscous digipeat function filled the need. The viscous feature digipeats an eligible packet ONLY if another station did not digipeat the packet within the configured time frame.? This worked perfectly when I was trail running in the "ify" coverage area of a mountaintop digi. Eric WB6TIX |

Re: Auto run a program
开云体育The weather data is continually updating (each 2.5 seconds for wind, e.g.), so the script needs to run periodically to get the current weather status. I use weewx which defaults to five minute updates, a good compromise.Ray vk2tv On 27/2/23 19:28, Andy McMullin wrote:

Re: Auto run a program
开云体育This might get you pointed in the right direction. It's from a larger shell script that does much data manipulation, likely very unnecessary for you. The script is run each five minutes from a crontab job.#!/bin/sh cd /home/vk2tv/getweather/freddo # use lynx to get data from server and write to file rawweather. lynx -dump > rawweather Ray vk2tv On 27/2/23 12:01, Patrick KA9PDK wrote:

Auto run a program
I have a?Raspberry Pi sitting on a shelf thinking about the weather. Every so often, it generates a web page, which I can get to from anywhere. Typically, I manage it remotely as there is no monitor or keyboard. One day, I plugged in a monitor and when I rebooted, it auto logged in the user pi and showed me its?desktop. Great I thought, now I only need it to auto run lynx which will point at my weather web page. There in lies the problem, how to run lynx and show a web page. Keeping it from going to sleep and blanking the display is fairly easy, but so far, getting it to run lynx is a headache. Any thoughts? -- Patrick |

Re: Raspberry pi & TNC-Pi9k running aprx
Some older and very inexpensive Handhelds work very well. I ran a packet station for a couple of years using the handheld RadioShack 2 Meter handheld connected to an outside vertical at 5 watts and never once had a problem (I believe it was manufactured by Icom for a few years).

Re: Raspberry pi & TNC-Pi9k running aprx
Commercial VHF radios (Kenwood, Tait, etc) can often be found at hamfests or on eBay for less than $100. They make great radios for APRS. The trick is programming them for 144.39, but there are ways to do that. Be sure you buy a radio that is known to operate below 148 MHz; not all commercial radios will, at least not without an adjustment.??

If a radio fails the final QC, it becomes one of the failed units in a shrink-wrapped pallet that gets auctioned to the highest bidder and subsequently sold for very cheap on eBay and similar sites. Paying a wee bit more to a reliable, reputable dealer like baofengtech.com is well worth the small price difference. |

I totally agree 100% m.? Some Baofengs work and some identical ones just don't work.? They are very cheap radios with no quality control and completely unreliable. A friend of mine almost gave up the hobby because he bought a Baofeng as starter radio and couldn't make any contacts on it. He thought it was because the band was dead but it was actually a faulty radio.? We tested it.? He couldn't make a contact with me even though I was standing 20m away!? ?
Get a Yaesu FT4X.? They are the cheapest most reliable little radios you can buy and can't go wrong by them.? Mine fell 10m off a balcony and survived.? You should be able to run a TNC with this radio.? Another great one to try is the Kenwood TMV71.? It's a 50W mobile rig, but also pretty solid with APRS features too. Austin M0MNE? |

Re: Raspberry pi & TNC-Pi9k running aprx
开云体育Hello Lorin, Here is my setup that I’m working on at the moment and really struggling with the decoding of beacon. Raspberry Pi with TNC-Pi9k installed and a Baofeng UV5R radio for broadcast and listening with DIY cable. So far I’m sucessful with transmitting a beacon, but decoding what is coming in is failure so far, I decode one in 2000 randomly. If you search the email archives here on this list, you will find a LOT of users having a broad range of issues with these cheap radios.? Some people have success with one radio but nothing but failures with another identical radio next to it.? It's very difficult to give specific reasons why but it usually boils down to poor quality control.? You can try to continue trying with this radio but the general recommendation is to just use a better radio.? Using a good radio will get you a lot more reliable results and far better decodes. Anyway, that said, if you read Mark Griffith KD?QYN article on the TNCPi-9k6, Page 7 at , he states for the RX levels: -- Most radios use a level of about 300-500mV for receive audio. Setting the receive audio register to match would be necessary, except John has programmed into the software the ability for the receive audio to be automatically adjusted depending upon the level seen on the RX input. This level is constantly being adjusted. However, in my initial testing, I found that at 1200 baud, a receive audio level of 50 (~500mV) -- If you have an ocilliscope, then shoot for that 500mV target but most people don't have scopes.? Not all is lost though.? If you then scan down to the bottom of page 9, there is mention of the DEBUG port and how to connect to it.? It's possible that newer versions of the TNC firmware might give information about the receive level and how you might adjust the output level from your radio to best suit the input into the TNC. The radio receives, the tnc board light up when receiving, but the nothing in the aprs software (aprx). The LED you're talking about here is the DCD light meaning it's able to detect the lowest level HDLC bit pattern.? That's a good start but it doesn't mean the TNC is decoding any real higher level packets. Played with radio volume, played with the rx setting, but no avail so far, anyone with some pointers would be great. Doing a quick Internet search on: ?? tuning audio levels for TNC- "Pi9k" gave several strong hits.? Try reviewing this one thread talking about this specific TNC and how to tune it: ?? /g/bpq32/topic/37942342#23364 --David KI6ZHD |
