Possible record auction price for a Panasonic RF-8000

12 Replies

Many thanks to SWLing Post contributor, Dan Robinson, who discovered this excellent condition Panasonic RF-8000 which recently sold on eBay for $5,100 US:

Dan believes this is possibly a record price for this receiver. I would tend to agree. It does look like a beautiful receiver.

Any SWLing Post readers own a Panasonif RF-8000? What do you think of it?

John responds to the Wired.com review of the Como Audio Solo

Many thanks to SWLing Post contributor, John Figliozzi, author of The Worldwide Listening Guide, who comments with this critique of the Wired.com review of the Como Audio Solo:

I wonder how experienced this reviewer is with this class of audio devices.

First he states that the Solo receives AM. I doesn’t. (Unless you count receiving AM stations via their Internet streams.)

It does receive FM, although its sensitivity to fringe signals is a bit substandard comparatively, even with the built-on rod antenna. He notes a disappointing audio performance at higher volumes, but fails to distinguish between sources. Lower bit rate digital audio does reveal its insufficiencies with increased volume, but that would be true regardless of the speaker ratings.

A 30 watt RMS driver/tweeter speaker combo in a box this compact bespeaks a pretty efficient and powerful digital amplifier that would shine if fed audio of sufficient “heft”. With so much compressed digital audio out there–especially on Internet radio–it’s hard to judge what the objective limits of this unit aurally truly are.

He also doesn’t seem to be conversant with the set-up process, which is quite intuitive, or the fact that the unit comes with a remote.

At $300 MSRP, it is premium priced and will be too rich for the blood of some. Furthermore, its Internet station list as provided by Frontier Silicon seems a bit more limited than others I’ve experienced. But it is beautifully designed and presented and is quite versatile. Then again, as much as I like it, I can’t see myself populating my home with one in every room. There are other products out there that do this more efficiently and affordably.

Here’s a $300 internet radio review from Wired:

Click here to view on Wired.com.

I was an early backer of the Como Audio Solo and reviewed it in October.

Since then, the Solo has become my WiFi radio of choice. I have it hooked up to an SSTRAN AM transmitter and use it to pipe audio through my whole house via the AM broadcast band. Though this only concerns a tiny fraction of hard-core radio geeks: the Solo has a very quiet power supply and my AM transmitter picks up no hum from the Solo. All of my other WiFi radio induce a hum if connected to mains power. This is what makes the Solo so useful in my household and shack.

Of course, when I have it tuned to a music station, like RFI Musique, its built-in speaker system provides ample fidelity!

As I mention in my review, FM analog reception is mediocre, though I imagine it would improve with an external antenna. Wired believes the Solo is good, but not great.

Trying to chose between the CC Skywave and Tecsun PL-310ET?

1 Reply

Many thanks to SWLing Post reader, Joe, who recently asked in our comments section:

“The CC Skywave is more than double the price of the Tecsun PL-310ET. The two radios appear to have similar features and performance. Can anyone suggest a reason why one would want to pay the extra charge for a Skywave?”

Thanks for your question, Joe. I’m asked this a lot by SWLing Post readers, so quickly realized I should just turn my response into a proper post. Here’s my response in a nutshell:

The Tecun PL-310ET

The Tecsun PL-310ET is (and has been for years) one of the best budget shortwave portables out there.

For the price of $40-45 US shipped (via eBay, for example), you really can’t go wrong. It’s certainly a benchmark among the ultralight DSP portables.

The ($79-89 US) CC Skywave, in my opinion, has a few advantages:

An excellent weather radio receiver (for folks in North America)
The AIR band which is a fun and useful addition if you live near an airport or like travelling by air
I prefer the Skywave over the PL-310ET on the mediumwave band. Its selectivity and AGC, in my opinion, have a distinct edge over the ‘310ET for MW DXing.

Because of these particular advantages, the Skywave has become my travel portable of choice when SSB reception isn’t a priority.

The CC Skywave

You might check out my CC Skywave review because I tried to include reception recordings which I felt represented both radios fairly:

In short, though? If I didn’t care about the AIR band or NOAA weather radio, I’d be quite happy with the PL-310ET. In truth, you really can’t go wrong either choice.

I can say that I now take my CC Skywave on travels more than my PL-310ET.
