Max’s Barlow Wadley receiver is a keeper

Barlow-Wadley-FM

In reply to our post about the Barlow Wadley XCR-30, SWLing Post reader, Max Youle, replies:

I have a Barlow Wadley with the FM tuner here in New Zealand. [see photo above]

These fabulous receivers are reasonably common here as many SWLs bought them in the 1970s because of New Zealand’s remote location

My Barlow Wadley has just recently had an alignment and a thorough going over, and will now match my Sony ICF 2010,and Yaseu FRG 8800 for stations received on the shortwave bands, but not so good on the MW band.

I love this radio, and its quirky tuning system. This reminds me of the days of knob twiddling to find those elusive signals, not like the ease of todays digital receivers.

Thanks for your comment, Max. Your Barlow Wadley portable is certainly a keeper! Perhaps someday one will find its way to my radio room!

MegaLoop ML052: Bonito’s new portable mag loop antenna

(Source: Bonito Press Release)

At the beginning of the model year 2016, there is good news in the range of our MegaLoop Active Loop Antennas:

New Model: MegaLoop ML052

MegaLoop ML052The new Active Loop MegaLoop ML052, which is available end of February, is the successor to our MegaLoop 060. Based on the proven technology of theMegaLoop 200 platform, an additional low pass filter with an extra FM-band-stop was integrated. Thus, the ML052 is especially suitable for operation near strong FM-stations and higher frequencies , where, because of its broadband capacity, the ML200 could be overloaded by strong signals.

Frequency range:
Low Gain: 9kHz – 52 MHz
High Gain: 9 kHz – 36 MHz
Suppression on FM (88 – 108 MHz): max. 40 dB

Intercept Point
IP:3: typ. +40dBm
IP2: typ. +84 dBm

The effect of the integrated filter can be seen very good on these two images:

ML052 in High Gain Mode

ML052 in High Gain Mode

ML052 in Low Gain Mode

ML052 in Low Gain Mode

Like the ML 200, the amplification of the ML052 can be changed internally with a jumper:
a) High Gain: 0-36MHz
b) Low Gain: 0-52 MHz (-7dB)
Suppression of the FM band: (88-108MHz): max. 40dB

Outstanding intermodulation surpression, with only 5 volts!

CPI1000 with Powerbank

CPI1000 with a standard Powerbank

The MegaLoop ML052 achieved outstanding values regarding intermodulation suppression even at a low supply voltage from only 5V. It can be powered either by a conventional plug power supply or even via USB. Powering via USB has the advantage that no external power supply is needed and that the antenna can be used autonomously and noise-free with a separate USB power bank. A appropriate dual power input adapter (CPI1000) is already included in the standard package.

The MegaLoop ML052 can now be pre-ordered in our eShop underwww.hamradioshop.net. In the UK at Taylor Made RF.

Auction Score: a Sony ICF-SW55

Goodwill-listing

Regular SWLing Post readers know that I’m a sucker for classic solid-state portables and vintage tube radios.

What many of you may not know, however, is that I’m not a fan of auction-style bidding for radios. Those who are familiar with it will recognize the story: it begins on an optimistic note, when I find something I’m enthusiastic about.  Then the bidding war begins, and invariably, the price quickly ratchets upwards to far beyond my comfort zone.  It’s only then I find I’ve wasted my time on the entire process, and my hopes are dashed.  So it’s not a purchasing method I relish.

Therefore, despite all of the radio gear I’ve purchased over the years, I’ve only bid for a radio in an online auction perhaps three or four times.

But a couple of weeks ago, my buddy David Korchin (K2WNW)––who has a knack for finding deals on radios, and often alerts me to them––mentioned that he was bidding on a Sony ICF-SW55.

David wasn’t bidding on the popular online auction eBay––rather, he’d found this deal on ShopGoodwill.com.

A note about ShopGoodwill.com

ShopGoodwill-ScreenShot

In case you haven’t heard, ShopGoodwill.com is Goodwill Industries International’s online auction site.  Goodwill employees select exceptional donations, items they feel are worth more than typical Goodwill retail prices, and post them there for online auction.

I believe it was SWLing Post contributor, Mario Filippi, who first introduced me to ShopGoodwill.

The cool thing about ShopGoodwill is that it’s not as popular as, for example, eBay. Thus a bidder has a better chance of finding a good deal, with the added benefit that less enthusiasts will be hiking up the price with rapid bidding.

There are issues with ShopGoodwill.com, though, some of which are very off-putting:

  • Items are often poorly described, thus:
    • searching through the collection can be rather difficult
    • you often can’t trust these condition descriptions, as they’re written by someone who is clearly not an expert
    • Photos are sometimes of low quality, low resolution, and rarely offer enough detail for an informed decision
  • Buyer beware: nearly all items are sold “as-is,” and are untested
  • No returns on most items
  • No real seller feedback: if you’re frustrated with a Goodwill shop, you have no real recourse other than complaint

So, in summary: unless otherwise specified in the listing, you must assume that any item offered for auction on this site doesn’t function and may be in poor cosmetic condition as well. After all, these are donated items.

With that said, even though the risk is higher than on eBay–where sellers are rewarded with positive feedback and endeavor to fully describe merchandise––some good deals are occasionally to be found on ShopGoodwill!

Now back to my story…

The Sony ICF-SW55 listing that David found on ShopGoodwill.com kept a steady bid of $28 until the day before the auction’s end, when it increased to $48 US.

It’s likely that this listing would have seen more active bidding if the description were better––it didn’t even provide the model number, and was listed as “Sony Worldband Portable Receiver.” Moreover, the feature photo for the listing was of the radio’s case, not the radio itself (see below), yet another reason the listing got so little attention. But David, being the deal hound he is, found it!

I encouraged David to really go for it, saying that this could be an excellent opportunity to snag one of these classic portables for a good price. And if it didn’t work, there would be a good chance Vlado could fix it for a fair price.

The morning the auction concluded, David messaged me that he’d decided to pull out of the bidding. He found something else he wanted to snag, so he encouraged me to take the baton and bid on the ICF-SW55, myself.

I read the vague description…then took a deep breath, and decided to go for it!

Sony-ICF-SW55-Listing-Description

Again, I’m not adept at bidding, but at least I have a method that has worked for me in the past. My simple rules:

  1. Only bid once.
  2. Wait until the last few seconds, then offer my highest comfortable bid.

Final bidding, blow-by-blow

Here’s how the final moments of the auction played out:

I waited until one minute before auction end. I decided I would go as high as $120––a little rich for my modest budget, considering this could amount to a parts radio, but it was late in the day and I admit I wasn’t thinking clearly.

Then, at thirty seconds before auction’s end, the ShopGoodwill.com site simply stopped responding––!

Error-Chrome

No, it wasn’t my dubious Internet connection this time––their site was having problems loading.

finally got the auction screen to pop back up ten seconds before auction’s end. I quickly attempted to place my bid: the web page churned…and churned…and churned.

Finally, up popped the review screen at literally the last breath of a second. I clicked “confirm/submit” (thank you, LastPass, for filling in my password immediately) and just managed to record the bid!

I’m certain that my bid was received within the last second. I had the countdown clock running on my Android phone so I’d know when the auction’s end was coming up. Unlike eBay, there is no dynamic counter on ShopGoodwill: you must refresh the page to see the time remaining. The Android countdown was set to end three seconds before the actual end of auction. When I confirmed the bid, it read “-3 seconds.”

The Goodwill site was having so many problems, that it took it two full minutes before I could get the auction screen to refresh after it accepted my bid––it was still stuck on the screen that confirmed my bid was recorded and that I was––for the moment, anyhow––the highest bidder.

When the page finally loaded, I saw that I had, by the skin of my teeth, snagged the SW55, and for a mere $53.

ShopGoodwill-WinningBidThat is one of the lowest prices I’ve ever seen one of these units go for in an online auction, even when listed as a “parts-only” radio.  Needless to say, I was exhilarated!  My heart pounded.

I’m certain that the problem with the Goodwill site helped me win the auction. There were multiple bidders, and I think mine just happened to trigger a bid, leaving the competition no way to outbid me in the last 1/10 of a second.  This wasn’t bidding skill.  And it surely wasn’t a fat wallet.  Frankly, I was just lucky.

I was thrilled to have won the radio at such a relatively low price, but the relief afterward reminded me why I don’t like auctions like this. I definitely prefer a more straightforward, less exciting (and less anxiety-producing), approach to making purchases.

Good news comes in small packages

Sony-ICF-SW55-Front

Goodwill can be relatively slow to ship.  It took about two weeks, but on Monday, I received the package from Goodwill in California.  The rig, save a little dust, looked fine.  But…how would it function?

I put in some freshly-charged Enloop AA batteries and turned it on.

Much to my surprise, the rig turned on…I rapidly tested all the functions. Again, I couldn’t believe my luck: it functions perfectly!

Sony-ICF-SW55-Right Side

The only feature in need attention is the DX/Normal/Local switch, which makes the rig sound a bit scratchy when I change positions––an easy fix, however, with the aid of a little DeOxit.

Sony-ICF-SW55-back

This auction had a happy ending: I got a radio I’ve always wanted for a price I could swing, I didn’t need my friend Vlado to come to my rescue (though I’ve no doubt he would have), and best of all, I find I absolutely love the ICF-SW55.

Sony-ICF-SW55-3

Stay tuned…A review of the classic SW55 is in the works, and will be here on the SWLing Post in the coming weeks!

Gary discovers a way to lock narrow filters on the Tecsun PL-880

PL-880 (1)

Many thanks to SWLing Post reader, Gary (WN9U) who writes:

Just an FYI comment about the narrow filters NOT staying on while tuning. I read about the similar problem that you encountered during the initial testing of the PL-880.

While tuning CW stations with the 500 Hz filter turned on (fast or fine tuning), the filter would always revert back to the 3.0 wider setting. It had never done this before. I tried several resets with no cure.

After further testing I found the fix: I had turned on the Hidden Menu Noise Reduction (switch 6) and did not realize it was on.

After turning off the Noise Reduction, I was able to tune with the narrow filters set at any band width. Evidently, the filter opens up to 3.0 when tuning with the Noise Reduction turned on & reset does not turn off this function.

Thanks so much for the tip, Gary! I’ll add this to our (still) growing list of PL-880 hidden features and tips. Seems there’s always something to discover on the Tecsun PL-880.

Val compares his Sony SRF-59 with the SRF-39FP

Sony-SRF-59-and-Sony-SRF-39FPMy buddy, Jeff MacMahon, over the Herculodge, forwarded the following message from his reader, Val:

[P]robably some people who are still interested in AM radio will be surprised to see pictures of the Sony SRF-59.

[The] Sony SRF-39FR is an excellent receiver made special for Federal Prison in US.

It is an incredibly sensitive and selective receiver able to pick up every AM frequency.

Somewhere on the Internet, I found a picture of the SRF-59 [which implied that it had the] same circuitry as the Sony SRF-39FR.

I bought SRF-59 from Source Electronic to compare two radios. I was so disappointed after testing the SRF-59.modern-sony-srf-59

It is absolutely a different receiver compared with the SRF-39FP. It doesn’t stay close for performance. I opened it (see photo above) and (surprise!) it was missing a few capacitors…What a shame….

Thanks for sharing this, Val.

My advice? Don’t throw the SRF-59 away yet, Val! While it isn’t quite on par with the SRF-39FP, it is still quite an amazing MW DX ultralight.

I would suggest that you check out Dave Richard’s blog where he details how to tweak the SRF-59 for top performace. Dave’s article includes excellent detail and great photos. Click here to view.

Radio Go Bag: JC recommends this affordable shoulder pack

Bag-TacticalSpeaking of backpacks and protective cases for radios, SWLing Post reader, JC, recommends an inexpensive tactical shoulder pack available via eBay.

JC writes:

I tend to want a little more protection and space so I use a tactical military type shoulder bag for my portable radio kit. It hangs nicely off the back of the passenger’s seat in my car and allows me to keep my PL-660, spare batteries, portable wire antenna, earphones, frequency lists, and other gear all together in a handy pack.

The price is about $13.60 w/ free shipping. It’s a great bag for my portable kit, and it’s built pretty sturdy. Any extra protection is better than none for a radio used out in the field.

Thanks for the recommendation! That is incredibly affordable and a great looking bag.

I’m very partial to Spec Ops Brand packs, but they’re quite pricey in comparison.

Protecting your investment: Troy’s radio case recommendations

IMG_1293Many thanks to SWLing Post contributor, Troy Riedel (the Amateur Astronomer), who writes:

I’m rather – uh – call it OCD re: equipment cases (and bags/packs).

All of my […]astronomy equipment is well secured & cataloged in several dozen cases.

I [also] wanted to protect my shortwave radios. I like the neoprene cases that Tecsun ships with their radios as they have a bit of shock absorbing capacity. I went online at Amazon & eBay and I bought “neoprene” cases of various sizes made for GPS units, external hard drives, and tablets.

IMG_1292

Upon receiving them I’ve found the 3.5-4″ GPS cases are perfect for the Grundig G6 and similar sized radios.

IMG_1295 IMG_1290

Belkin “Grip” tablet cases are perfect for the Grundig G3/G5. And the larger “iLuv Gaudi” case is prefect for the YB400 & Sony ICF-SW7600GR. The iLuv even has memory foam. I feel I could drop any radio in this iLuv case from a reasonable height and the contents would be perfectly fine.

Including shipping, I spent $6 for the most expensive case and as little as $3.95 for the least expensive.

IMG_1294

The iLuv memory foam case, in silver, was only $4.99 and free shipping via Amazon Prime. Some of the cases have exterior zipped pockets perfect for ear buds and a USB cable. The neoprene has the capacity to stretch a bit, so all of them are a snug fit. Though there is an extra 1/2″ on the iLuv case, the memory foam quality ensures a nice, tight fit.

I’ve attached a few pictures to illustrate my finds.

BTW, I also noticed today that The Worldwide Listening Guide is priced at $21.62 on Amazon. That’s down from $24.95 and a good deal with Prime.

Thanks so much for sharing your research, Troy. I have just added the iLuv case to my Amazon cart. Like you, I have a Sony ICF-SW7600GR and it gets taken to the field a lot. The 7600GR comes with a nice custom case/cover, but it offers little in the way of protection–$4.99 is a reasonable cost to protect one of my favorite portables.

Like you, Troy, I have a serious addiction to quality bags and cases.  I hope you know that you’re only enabling me! Ha!

Readers: Please share your radio case/bag recommendations as well!
