Afedri SDR received – first impressions

Received the Afedri SDR last saturday, and have been listening around with the it during three days now, and I must say that I’m impressed by it’s performance versus it’s price. There was a few “hickups” during the setup-process, but thanks to help and assistance from Alex and a number of members in the Afedri yahoo-group, everything went well. I’ve noticed that the stock AC/DC adapter to my laptop (Asus X35E) generates about 5-6 dB of noise, so I have been running the PC on it’s internal battery. However, powering the Afedri from the PC’s USB outlet “eats” battery, and running the PC in “powersave modus” isn’t an option, because it seems that the Afedris VGA doesn’t work properly (I will investigate this closer later on). I have modified an USB cable to allow me to power the Afedri from a regulated (non-switch mode) power supply adjusted to +5V. This works really good, and allows me to run the computer on it’s own battery in powersave modus, without less performance from the Afedri.

In any case, I think that the Afedri SDR represents an exceptional value, considering it’s price. I think it’s very similar to the SDR-IQ (I haven’t yet tried any other SDR’s). The IF-recording capabilities is really impressive, and extremely useful during MW-DXing sessions. I beleive that the Afedri will become a very useful tool during my Aihkiniemi DXpedition later this season.




About Hans

Male. 50 years young. DX:er since 1980. In September 2011 I moved up to Vardø on Vardøya Island (EU-141) to start working as manager for the Coast Radio station in Vardø. I feel very lucky to have this opportunity to work with the thing that I think is the most interesting in the whole world - Radio! My main interest is, yeah - you guessed right: Radio. I'm a ham radio operator, holding the callsign LA2MOA. My main radio interests is low power operation and low band DXing on the amateur bands, but also mediumwave and tropical band DX-listening. I'm also interested in angling, fly-fishing and fly-tying. The area around Vardø offers some great opportunities to do all of this. And, since I'm of swedish origin, I'm also madly interested in ice-hockey and since 35 years I'm a hardcore supporter of Rögle BK in Ängelholm - one of the few really true hockey clubs left in Sweden.
