Good find of all the frequencies and powers, it sounds like you have all the right basic equipment. But sadly for the roadster, you're too late, it's out of range. The video link is designed for a few hundred km, and it's probably half a million km away already. Assuming the batteries on the spacecraft are still OK. It's transmitting 44 dBm. The path loss ...

if a number of these devices are transmitting on a specific channel, will a receiver walkie talkie be able to hear all the signals coming from the ground sensors? The exact result depends on the modulation used, but in no case will it be all that useful. If they use FM (almost certain for any modern off-the-shelf equipment), you will hear mostly the ...

ยง97.215 has rules for "model craft". It says a station may be operated under those rules. To me, the intent of those rules is to allow for control of RC models without a break to identify every 10 minutes. I'd guess for a rover designed for Mars, a brief identification break is not a problem. However, the rover is a station, and there won't be anyone at it. ...

If you wish to transmit a measured parameter under US FCC Part 97 regulations, you would be operating under the telemetry rules. This is defined as "A one-way transmission of measurements at a distance from the measuring instrument." Telemetry transmissions are generally permitted under the same conditions that "Data" transmissions are permitted. The ...

The batteries are now dead and there is no onboard power source, so we cannot listen to it. See the comments at https://space.stackexchange.com/questions/25010/current-position-of-starman

I understand that the HX-1 Radio Transmitter is an APRS, but how can I receive transmissions from this system? Could I track this with a RTL-SDR dongle? Yes, an RTL-SDR dongle and Direwolf is one good way to receive APRS; there are many others. You can also rely on existing receivers passing data to the APRS-IS. Also, with the NEO-6M GPS how do I receive ...
