Testing the MIX4ALL Downconverter on L-Band
Adam (9a4QV) is well known in the RTL-SDR community for creating and selling the LNA4ALL low noise amplifier and several filter circuits as well. Now Adam has uploaded on his YouTube channel a new video that shows a prototype of his latest upcoming RTL-SDR compatible product called the MIX4ALL. The MIX4ALL is a downconverter that will improve the ability of the RTL-SDR to receive satellite signals in the L-band which are usually at around 1.5 GHz.
It is known that the most common R820T/2 RTL-SDR’s are not very sensitive at 1.5 GHz, and some can even stop receiving properly at this frequency when they get too hot. A downconverter will simply convert the 1.5 GHz signals into a lower frequency which can be received much better by the RTL-SDR.
In the first video Adam shows the MIX4ALL being used with an RTL-SDR to receive various Inmarsat signals with a patch antenna. In the second video he shows reception of AERO-I signals.
Adam writes that he expects to be able to sell the MIX4ALL near the end of January 2016.
Cant wait untill its out,And mounted at the antenna,Im getting AERO via the rtl sdr 820T2 stick and a 20 RHCP antenna on the 58west sat and JAERO.
