Here we take a look at the RS-HFIQ 5 Watt HF SDR Transceiver by HobbyPCB.
I have one of these, It's a nice little radio.
Very interesting, you do show some great products. Thank you.
SDR radios have an incredible W I D E front end. Therefore, put a pre-selector before your coax gets to the radio.
They don't do well for field day where close proximity RF fields abound.
Too bad the Peaberry went away.
Looks nice enough. Not a bad small radio
Very, very cool. FET final, I see: https://www.hobbypcb.com/index.php/products/hf-radio/rs-hfiq.
Cool, Qrp radio!
Just purchased one of these (used but like new) from fellow ham and am VERY interested in the device mentioned at the end of the video (which I am guessing is a Raspberry Pi pre-programmed to turn the SDR into a complete rig). More info? Also interested in knowing which amplifiers can work with a rig with such low power output and bring it up to, say, 100W. (Due to the FCC's silly 15dB limit, most amps seem to need a lot more than 5W.) I understand that HobbyRF makes one but am also interested in alternatives such as Xiegu.
It only takes 13 dB to go from 5W to 100W.
The lack of sufficient gain in any given amplifier is the limiting factor here, not "the FCC's silly 15dB limit".
Only for a Windows-Platform? Not really worth to get one. When the software gets more compatible to other solutions maybe. Here is the Kiwi SDR a got example for, how it should work.
