Sony CRF-320 sighting on eBay

 

SonyThis morning, while scanning eBay, I ran across this serviced and restored Sony CRF-320. It’s listed with a BuyItNow price of $1,795.00 plus $63.30 shipping. Though that price seems steep to me, it appears these trend for $1,880 on eBay.

SonyCRF-320The CRF-320 is certainly a beautiful receiver and, aesthetically, everything I love about radios of the era. I’ve never had the pleasure of operating one, and–though I’m a bit of a radio collector–it’s simply out of my price range. If I ever manage to procure one, it’ll probably be a fixer-upper or a garage sale find. Well…one can dream…

I’ve heard the CRF-320 is a true performer. I’m very curious if any SWLing Post readers have one. If so, please comment with your thoughts or even a review!

Virtual Radio Challenge III: Thru-hiking the Appalachian Trail

On this blog, I often write about selecting the “right” radio for home, boating, preparednessoff-grid living, or, of course, travel.  As a result, sometimes I like to go through the mental exercise of imagining a scenario that might be, well, a touch extreme.

After all, as I’ve often said, SWLers come from such interesting walks–even hikes–of life, and often pose the most intriguing questions.

Indeed, I occasionally receive rather “extreme” questions from our readers, questions that push the limits of the hobby in the most exhilarating way, demanding highly specific needs in a radio. And (I readily admit) I thoroughly enjoy these questions.  Such queries give me a chance–and good excuse, really–to be imaginative and innovative, to push beyond mere practical or monetary constraints to consider unique environments, weather conditions, durability needs, power requirements, and/or resource availability…all great fun.

If you enjoy this kind of brain game, too, check out our virtual challenge that follows–and, oh, and did I mention…

This time, there’s a prize

GP5SSB-Front

The CountyComm GP5/SSB

Dennis Blanchard (K1YPP), Appalachian Trail thru-hiker and author of Three Hundred Zeroes, which chronicles his adventures on the trail, will select his favorite entry in this reader challenge, and Universal Radio will reward the entrant with a new CountyComm GP5/SSB portable receiver! Woot!

So, should you agree to take it on, you’ll need to complete and submit your entry by August 8, 2015 at 06:00 UTC.

Thru-hiking the Appalachian Trail

[This scenario is based on an actual reader question.]

AppalachianTrail-Map

Virtual Location: The Appalachian Trail

Accommodation? Tents, hammocks, and lean-tos on the trail; occasional hotel or hiker guest houses

Electricity? Other than rest days, you’ll be completely off-the-grid

Internet? You can choose to carry a smart phone with you on this hike. Since most of the trail is in rural, remote areas, Internet access will be sporadic on your journey.

Your budget? $300 US must cover all of your radio requirements (radio, antenna, batteries, battery chargers, and all accessories)

Your radio(s)–??? You’re searching for portable radio gear that can receive shortwave, AM (medium wave), and FM. You’ll also need NOAA weather radio functionality to help you plan each day on the trail and make accommodations for frequent spring and summer thunderstorms (and occasional spring snow or sleet).

Virtual scenario: Imagine you’re a recently-retired stockbroker fulfilling a lifelong dream of thru-hiking the Appalachian Trail. You have cleared out most of the year for uninterrupted hiking, starting in Georgia and ending in Maine. You’re covering all of your logistics, travel, and living expenses while on the trail.

Being an avid shortwave radio listener, you see this hike as an opportunity to spend quality time listening to radio–while hiking and camping–in remote areas that are completely removed from urban radio interference you experience at home.

Although you’re looking forward to “unplugging” from the world of stock trading, you’re still keen on listening to international and local news so you’ll know what’s happening in the world of finance and business.

It goes without saying that you’ll carry all of your supplies–your food, camping supplies, clothing, etc.–and all on your back. Minimizing your backpack weight is clearly of utmost importance.

Limitations

Rather than making this virtual challenge more restrictive, these limitations are designed to make the challenge more fun and set a level playing field for all respondents.

  1. Again, you’re limited to a (virtual) budget of $300 US to procure your supplies; ideally, this includes shipping costs of the purchase
  2. You can select new, used or homebrew/kit gear, but must base your choices on reality (i.e., actually find item(s) online and document the price and time of availability). If you “shop” eBay, make sure you’re using the final purchase price, not the current or opening bid. If you do locate something used on eBayQTH.com, QRZ.com or at Universal Radio, for example, include the link! (Just to add to the fun.) If you enter a homebrew radio, it should be based on something you’ve either built or used and must include a photo. Of course, you can use multiple radios, but keep in mind the amount of space and weight these will take up in your backpack.
  3. Your main objective is to listen to international and local broadcasters and NOAA weather radio. If you’re a ham radio operator, by all means, you’re invited to include a transceiver in your trail kit (indeed, many do have AM/FM/SW reception), but keep in mind that our accomplished A.T. thru-hiker judge will base his decision on the best set up for listening to NOAA weather radio and international, local and broadcasters.
  4. Remember, you’ll be stuck with this radio once you hit the trail! So choose something you’ll love to operate, and don’t forget your vital accessories. Note that there are many points of the Appalachian Trail that are in proximity to towns and cities; you can get additional supplies there as needed.

About the Appalachian Trail…

Appalachian_Trail_at_Newfound_Gap

If you’re not familiar with the Appalachian Trail, you’ll find a wealth of information about it at the Appalachian Trail Conservancy’s (ATC) website. The following is an ATC description of the trail:

The Appalachian Trail is one of the longest continuously marked footpaths in the world, measuring roughly 2,180 miles in length. The Trail goes through fourteen states along the crests and valleys of the Appalachian mountain range from the southern terminus at Springer Mountain, Georgia, to the Trail’s northern terminus at Katahdin, Maine.

Known as the “A.T.,” it has been estimated that 2-3 million people visit the Trail every year and about 1,800–2,000 people attempt to “thru-hike” the Trail. People from across the globe are drawn to the A.T. for a variety of reasons: to reconnect with nature, to escape the stress of city life, to meet new people or deepen old friendships, or to experience a simpler life.[…]

FUN FACTS

    • The Trail is roughly 2,180 miles long, passing through 14 states.
    • Thousands of volunteers contribute roughly 220,000 hours to the A.T. every year.
    • More than 250 three-sided shelters exist along the Trail.
    • Virginia is home to the most miles of the Trail (about 550), while West Virginia is home to the least (about 4).
    • Maryland and West Virginia are the easiest states to hike; New Hampshire and Maine are the hardest.
    • The total elevation gain of hiking the entire A.T. is equivalent to climbing Mt. Everest 16 times.
    • The A.T. is home to an impressive diversity of plants and animals. Some animals you may see include black bears, moose, porcupines, snakes, woodpeckers, and salamanders.
    • Some plants you may encounter include jack-in-the-pulpit, skunk cabbage, and flame azalea.

HIKERS

  • About 2 to 3 million visitors walk a portion of the A.T. each year.
  • The A.T. has hundreds of access points and is within a few hours drive of millions of Americans, making it a popular destination for day-hikers.
  • “Thru-hikers” walk the entire Trail in a continuous journey. “Section-hikers” piece the entire Trail together over years.
  • “Flip-floppers” thru-hike the entire Trail in discontinuous sections to avoid crowds, extremes in weather, or start on easier terrain.
  • 1 in 4 who attempt a thru-hike successfully completes the journey
  • Most thru-hikers walk north, starting in Georgia in spring and finishing in Maine in fall, taking an average of 6 months.
  • Foods high in calories and low in water weight, such as Snickers bars and Ramen Noodles, are popular with backpackers, who can burn up to 6,000 calories a day.

You’ll want to do your research before choosing gear for the Appalachian Trail Virtual Challenge! The more thought you’ve put behind your choices, the more likely your entry will be selected by our judge. Speaking of which…

Dennis Blanchard (K1YPP) is uniquely qualified for this challenge since he thru-hiked (which is to say, hiked in entirety) the Appalachian Trail in 2007, and carried at least one radio with him on much of the trip. He understands the advantages and limitations of operating from the trail. If you have no concept what it would be like to plan for and hike the trail, you might consider checking out his interesting and informative book, Three Hundred Zeroes, which chronicles his adventures on the trail. Dennis has kindly agreed to pick his favorite entry from reader responses.  Click here to read an interview I posted with Dennis on my ham radio blog, QRPer.com.

The selection process

Once our A. T. reader challenge closes on August 8, 2015, I’ll share all the entries with our kind judge. Depending upon the number of responses, of course, Dennis should have a favorite picked within one to two weeks of the challenge’s close.  We’ll announce the winner here on the SWLing Post, and shortly after, Universal Radio will reward the selected entrant with the new CountyComm GP5/SSB!

And note…we’ll also share a number of stand-out entries here with our readers!

SDRplay RSP: I bit the bullet!

SDR-PLay-RSPThere’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!

Came across this site on building a 3-transistor shortwave radio similar to the kit offered by Radio Shack years ago:

It was featured on the Instructables site:

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

RF2200
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.

Tecsun-PL-365-Ebay-Crazy-Price

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.
