Over on his blog KD0CQ has posted an interest check. He’d like to know if anyone would be interested in purchasing pre-modified SUP-2400 downconverters from him. We’ve posted about the SUP-2400 a few times in the past. Basically the SUP-2400 is a cheap (about $5 – $10 USD) DirecTV device which can be modified and turned into a downconverter for your RTL-SDR. A downconverter allows you to listen to higher frequencies, up to 4.5 GHz in the case of the SUP-2400 and an RTL-SDR.
The modification involves some decent soldering skills as it involves removing some small SMD components and using wires to bridge some points. KD0CQ writes that he’s thinking of selling premodified SUP-2400 units for $20 – $25 to interested customers. If you think that you’d be interested in this please comment on his post.
