Ping a ling a ding dong...my Icom 7100 just broke after 20 years of service. $15 is better than $1300.00 which is what I paid for that sucker 20 years ago.

I used to listen to FM radio on an old HP spectrum analyzer. I'm all for wide open radios with plenty of options.

Full text as always for my FRiends, from this blogger with the FR seal of approval. I would appreciate a click, though, if you don't mind I hope those on FR will give you that courtesy, and that they do the same for good-quality writing in general. It's a small payment for the value delivered - and thank you for an excellent and useful bit of writing.

My ICOM IC-T81A goes from 50 MHz to 1.2Ghz, but even with the mods to open it up, it is still limited on what types of modulation it will handle depending on what band it's on.
Sometimes it's just nice to listen to whatever, wherever.

My ICOM IC-T81A goes from 50 MHz to 1.2Ghz, My Kenwood TS-2000 goes from 1.8Mhz up to 1.2Ghz (not straight through of course..)
1.8-30Mhz is unlocked (recv/xmit straight thru.) I also get 50-54, 136-154, 220Mhz, 70cm and finally 1.2Ghz.

Thanks for posting this. I'm an Amateur Radio guy (General Class, studying for my Extra) and am interested in SDR also. Just ordered the Flex Radio 6700 (newest model) and am looking forward to playing with that.
Curious to know if the device you purchased would work on my 6-160 fan dipole?

Sure. You'll need an adapter from MCX to PL-259/SO-239.
If you're comparing it to the Flex Radio, though, the $15 dongle is going to come up a little short.
To: Pollster1

Indeed. In fact, there is a blogger who has produced a book that hints at that.
Funny you should mention SIGINT; I spent years in SIGINT and ELINT. Given how our government's capabilities in this area have massively evolved, and they are turning their toys on the citizenry, I'm thinking we should fight back. I think it's ironic that a Chinese TV dongle should help us do that.
To: BreezyDog
Well, you can’t transmit with it. And your ICOM is ten times the radio this thing is. But, for simple monitoring of public radio services, and your government, it’s just the thing.
To: mylife
The dongle can only look at about a MHz (1.024 MHz with a 2.048 MHz sampling rate). It is nice to be able see a slice of spectrum, because you can click on various signals, and SDRsharp will start to demodulate the signal.
