SDRplay RSP: I bit the bullet!
There’s a danger in doing radio reviews: sometimes, you get attached to the radio.
This was the case with the SDRplay RSP. SDRplay sent this radio to me on an extended loan and I’m grateful for the many months they’ve let me keep this in my shack and test drive it with various SDR applications.
My RSP review has been published in The Spectrum Monitor and now here on the SWLing Post. There was no need for me to keep it in the shack any longer, but as I reached for the return box, I simply couldn’t let the RSP go. Instead, I reached for my wallet, contacted SDRplay and paid for it.
I have no buyer’s remorse. The RSP is an amazing little SDR and so very affordable. At $149 US, it costs less than two of the latest portables I’ve purchased. As my review states, it packs maximum performance for its price class.
The RSP will become one of my travel SDRs since it’ll fit so easily in my radio go-bag. This will take a little pressure off of my Elad FDM-S2, which I like using in the shack and on extended vacations.
I can pack the SDRplay RSP with confidence when I’m doing one-bag, international travel, knowing that if it were to get lost or stolen, I’m only out $149. Plus, to a potential thief, the RSP box simply doesn’t look expensive.
When I have a little time, I plan to pair the SDRplay RSP with my Raspberry Pi. Of course, I’ll report on my progress.
Have any readers combined the Raspberry Pi and the RSP? If so, please comment!

A three transistor homebrew shortwave radio
SWLing Post contributor, Richard Langley, writes:
Came across this site on building a 3-transistor shortwave radio similar to the kit offered by Radio Shack years ago:

Very cool! Thanks for sharing this, Richard.
When I have a little time, I’ll go through my parts box and see how many of these components I already have. The author also supplies an excellent assembly manual for download and print. It would be fantastic if someone would kit up the parts list and offer it as a package. Regardless, this will make for a fun winter project!
An eBay caution: some sellers are out for a buck–or hundreds

SWLing Post contributor, Dan Robinson, has recently noticed exorbitant prices demanded by certain sellers on eBay. Dan writes:
As readers of SWLing Post know, Ebay prices–at least asking prices–can often go completely off the scale.
While it’s true that prices can be as high as the market will bear, some recent examples are cases in point. The RF-2200 by Panasonic was an amazing radio for its time, competing with the SONY 5900W and some other models back in the early days of sophisticated portables. The 2200 was known, and is still respected, for its directional AM loop antenna, and is a prized part of the stables of many SWL’s today.
But let’s face it…only a 2200 found new-in-the-box, or in [like]-new condition, should fetch anything over $250-300. Other examples recently include a DX-302 for which the owner was seeking something like $1200. Price inflation has also been seen with SONY ICF-6800Ws. The [difference] with these sets is that they truly are in new or 10.0 condition, worth several hundred dollars.
New SONY ICF-2010s–[and] there are still some circulating that are new-in-the-box or in [like]-new condition–can and do bring prices north of $400, sometimes more. So do new-in-box SONY ICF-SW100s if they are complete with all accessories, in the box–but beware, they should be the newer modified versions and not the old version (you can tell this by looking at the hinge on the SONY, which should have a notch to indicate the revised version of the radio).
Another classic portable that deserves somewhat higher pricing is the Panasonic RF-B65. In [new-in-the-box] condition, these can go for more than $300.
So, [unless] you’re seeing astronomically high prices for RF-2200s, stop and think about it. These are old portables, and you should not be paying exorbitant prices–UNLESS you [encounter] a time capsule with a radio in the box that was never used. Even so, buyers need to ask multiple questions of sellers to protect yourself.
I agree completely, Dan. If you want to purchase an item at a fair market price or even a bargain, you must do your research before simply using the “Buy It Now” option on eBay. There are plenty of sellers who charge fair prices still; leave the stratospheric-priced items on the eBay shelf.
A case in point (above): never mind the grammar error in the above listing, the $125 “Buy It Now” price for the Tecsun PL-365 is frankly excessive. The PL-365 is identical to the CountComm GP5/SSB–a radio I recently reviewed–and is available new from Universal Radio for $79.95 plus shipping. And since there are currently no other listings for the PL-365 on eBay (I’m not sure why) this price might appear reasonable to a new buyer.
This same seller initially offered the Tecsun PL-365 for a much higher price–in excess of $180, I believe. While this seller has excellent ratings, and no doubt would stand behind the product, the markup is simply too high for me to endorse (hence, no eBay link here).
In the past, I’ve also noted a semi-rare vintage radio–a “boat anchor” variety with a market price of perhaps $1,500–up for auction with a first bid amount in excess of $20,000 US! Yet I felt confident of the $1500 market price because I checked and cross-referenced it in Fred Osterman’s Shortwave Receivers Past & Present, which provides fair market values.
So, while I continue to support eBay, which remains one of the most secure platforms from which to buy unique and vintage goods on the open market, I want to encourage readers to heed Dan’s warning: research all pricing before making radio purchases on eBay…and keep the holes out of your pockets. Note that I will never directly link to unreasonable eBay listings.
Chris reviews the Sangean WR-22
Many thanks to SWLing Post reader, Chris Freitas, who has informed me about a review he just published of the Sangean WR-22 AM/FM clock radio.
The new Sangean ATS-405 shortwave portable
[UPDATE: Click here for a full review of the Sangean ATS-405]
Many thanks to SWLing Post contributor, Aaron Hyde, who reports that Sangean has a new travel radio on the market: the Sangean ATS-405.
Aaron writes:
“While looking around the internet today, I came across a new DSP shortwave radio called the Sangean ATS 405. The 405 looks a lot like its 404 predecessor except that it includes 3 bandwidths, 148 memories, a squelch control and comes along with some other interesting features.”
The ATS-405 came as very much a (welcome) surprise to me as Sangean hasn’t introduced a new shortwave radio in years. This radio is obviously based on a DSP chip and has three selectable bandwidths–I hope its AGC circuit is well suited for weak DX. I am a little disappointed the ATS-405 doesn’t have a tuning wheel. Still, I hope this will be a winner.
The ATS-405 owner’s manual (download here) lists the following features:
- Full shortwave 14 meter bands
- Five tuning methods-direct frequency access, auto scan, manual tuning, memory recall and rotary tuning
- ATS (Auto Tuning System)-auto scan and preset stations
- Shortwave meter band selection
- 148 station presets
- 2 alarm timers by buzzer and radio
- Real time clock
- Adjustable sleep timer
- Tone control (Music/Normal/News)
- 1 kHz fine tuning
- Squelch function adjusts the receiving threshold and eliminate weak transmissions
- Easy to read LCD display with backlight
- Eco-friendly recharging function with LED indicator
- Stereo/mono switch
I will plan to purchase an ATS-405 in the near future and review it in due time. Please comment with your impressions if you’ve purchased one!
The Sangean ATS-405 is available from the following sellers from $89.00 to 95.00 US:
Many thanks agin, Aaron, for the tip!
