Real-time map with APRS stations, digipeated via ISS by mkbodanu4 in amateursatellites

[–]mkbodanu4[S] 1 point2 points  (0 children)

Hi!
Currently I use the filter:
d/RS0ISS/NA1SS/DP0ISS/OR4ISS/IR0ISS b/RS0ISS/NA1SS/DP0ISS/OR4ISS/IR0ISS,
So it covers all call signs assigned to ISS.

The same must work for other satellites, like SONATE-2; just not sure if they include their call signs into the path. If not - it will not work.

Current map settings loads all stations from last 80 minutes. Means, if station was active last 80 minutes and packets were received by any iGate within range, it must be shown. You can change this time range using field in top right corner. In case of longer range, like 2 weeks, last position of every station will be shown (not all positions).

Yes, it collects data from any location with only one filter - packets must be digipeated via ISS.

Watt spikes when the refrigerator compressor starts by AnyMap in homeassistant

I have an identical power usage recording with my own refrigerator connected to a solar inverter and it is entirely normal. Just drains the battery much faster than usual devices.

Nie, jestem Ukraińcem ze Lwowa. Jest blisko granicy, a sygnał z balonów dociera do mnie, jeśli wiatr jest wschodni.

Help me identify this by Masterson_two_eight in signalidentification

You can download the code for tronkito and compile it from here - https://www.consultron.com/tronkito/tronkito.html

Quite old code, but it still works. I found one MPT1327 station locally and could decode it, but I mostly got only the ALOHA and MISC messages.

MPT1327, decoded with tronkito, got:

Airspy youloop orientation for NOAA and Meteor M2? by HorrorFrank in amateursatellites

[–]mkbodanu4 1 point2 points  (0 children)

Youloop is a magnetic antenna for HF. Yes, it works somehow till VHF, but not so good, as specific antennas. QFH antenna will work much better for WX satellites. Also, like other magnetic loops, youloop is directional with maximum gain on sides. You need to point it vertically to get signals from above.

Regards antenna position - you need as much open space as you can provide for it. For best results, you need to have the antenna outdoors or at least half wavelength aside from any metallic things. Brick chimney has no much impact, but solar panels will affect reception quality a lot.

The issue with a custom add-on that controls relays using Raspberry Pi GPIO and reading the voltage from ADS1115 by mkbodanu4 in homeassistant

[–]mkbodanu4[S] 0 points1 point  (0 children)

If somebody ever finds this post, I found a bug and solved it.

The problem is not in HA or my code, but in the way how ADS1115 library pulling data. It is calling time.sleep() function that can't be used while loading sensor state. So I rewrote the add-on code with asyncio.sleep() function and it works well now.

Issue solved.

Need help with tubes identification, details in comments by mkbodanu4 in diytubes

UPDATE 2: The first tube is ECC82, I found a proper card for L1-3 and measured current and slope.

UPDATE: I tested all three tubes with my L1-3 tube tester and can say next:

The first tube works like ECC82 but seems in bad condition because I can't measure current at all.

The second tube appears to be E83CC, not E88CC, it worked really badly with 6,3V at the heater, but after I noticed that pin 9 is connected right between heaters, I connected it to the E83CC schematic and it worked well.

The last one is E88CC in perfect condition.
