Found this interesting article about turning a #batdetector circuit into a #directconversion #receiver. It uses the #CD2003 radio chip.
I happen to have this very same bat detector so it is interesting to see how it works. Normally it mixes down signals from an ultrasonic transducer but it does that just as well with radio signals from an antenna 😋

Hat hier jemand Erfahrung mit einem #image für den Sat-Receiver Vu+ Solo?
#Vti hat dafür leider keine Updates mehr.
Die einzige Anforderung ausser "ganz normal" TV zu schauen, wäre #hbbtv

Voor de #hifi-kenners en technici: als ik een seventies sony receiver-versterker van 290W heb, die 2x40W kan uitsturen, maar dat ws nooit haalt, wat is dan waarschijnlijk ongeveer het energieverbruik per uur? #sony #seventies #str4800 #techniek #receiver #audio #audiophile energieprijzen #durftevragen #retoot

I have this set, witch was gummy and sticky because of the bad quality of the plastic. Those kinds of plastics became sticky with time.
The only way to make usable again, was to clean it with alcool.
It work, but it's not nice.
I have another set witch is in better condition, and I'm searching a better solution.
If somebody know...

Any radio folks have any idea what this is? (randomly found in the US National Archives, as part of the Bonneville Power Administration files with zero description; public) -- looks like 2Ghz? #mystery #radio #receiver #electronics

I also brought along the Panasonic RF2400-D DSP #receiver with analogue tuning to see how this performed on 648 KHz - although there is some fading (but less QRM from Spain in daytime) the reception is impressive given the distance from the TX - its comparable quality to monitoring Caroline from Caversham in the 80s when they were broadcasting directly from the Ross Revenge (around 10-35kW ERP, it varied over the years depending how much of the equipment was actually working) #radiomonitoring

#Airgapped computers can have sensitive data intercepted via the use of planted #malware and a #receiver (such as a laptop or smartphone) that gets the data through #electromagnetic radiation. Pretty wild! #Countermeasures have their own drawbacks, though curiously the method of interception doesn't seem to work that well with a laptop.
