Tecsun PL-680: Reader surveys closing today

TecsunPL680andPL660

If you haven’t had a chance to weigh in on the Tecsun PL-660/PL-680 comparison surveys, you will need to do so by 23:00 UTC today.

I’m working on the Tecsun PL-680 review and need completed surveys for graphs/charts. The review should be posted this weekend.

If you haven’t voted yet, here are links to each receiver survey with comparative audio samples:

Responses for these surveys has been, quite frankly, amazing! At time of publishing this post, we’ve received 367 individual survey responses! Thank you!

The Hallicrafters SX-88: a rare find and a gem of engineering

Hallicrafters-SX-88

Yesterday while glancing through the QTH.com classifieds ads, I noticed a rare boat anchor for sale: the Hallicrafters SX-88.

The seller, Jeremy, describes this SX-88 as follows:

Hi [t]here, I have one SX88 in minty shape and is one of a handful that came in military green on [the] front panel for evaluation by the military. This is an exceptional radio in amazing condition. I can provide pics for someone who is seriously interested. I am open to a fair offer on radio. Please, no low-ballers. We all know what [it’s] worth…

Halli-SX-88-QTH-Ad“We all know what it’s worth–?

Well, it just so happened that my good friend (and Elmer, or ham radio guru) Mike Hansgen (K8RAT) had recently provided me with a little history lesson on the subject of the SX-88, so I did know what this rig is worth: a great deal of money.

But curiosity got the best of me, so I contacted Jeremy (a nice fellow, by the way) and asked what he was expecting to receive in exchange for his Hallicrafters SX-88? Jeremy’s reply:

“…$5,500 USD will take it. It is a very rare unit; it was… only one of about 6 [painted green]…for presentation to the military for evaluation.

That price is firm. [I] will not negotiate downward, and shipping [from Ontario, Canada] is extra.”

After receiving this response from Jeremy, I happened to think that I have the reference guide to rare/used shortwave receivers: Fred Osterman’s Shortwave Receivers Past and Present 4th edition. (Click here for more info.)

Osterman’s wonderfully comprehensive guide mentions that the SX-88 is a “highly regarded, rare and collectible model.” As for the rarity of the SX-88, he describes it thus: “Extremely Scarce.” The used price range he gives is from $3,500-7,000 US.

I also have Chuck Dachis’ book, Radios By Hallicraftersin it, he states that the SX-88 is, “the most sought-after Hallicrafters model.” Wow.

After thanking Jeremy for his response, he replied:

“It’s a lot of money for a receiver for certain, but it is a fantastic shortwave receiver as the audio that comes out of it is amazing.

It has 10 watts of audio and into a big speaker–it is second to none. The fidelity is amazing and it is the king of its kind. [For those who like] tube rigs, it is the best of its kind.

For ham purposes on AM it is amazing, and on CW I find it incredible to use.

[W]hen they built this thing they intended to pull all [the] stops out and build the best radio they could for the day with the military in mind. It was an engineering marvel for the day.

Anyway, I have played with it for years now and need to thin out the herd.”

Impressive. And while I just don’t have that kind of money to fork out for a receiver, I did ask myself the question: “If I had $5,500 to blow, would I get that Hallicrafters SX-88?”

And my answer? Yes.  In fact, I would personally drive to Jeremy’s home in Ontario and bring it back; no way I’d trust it to a parcel carrier or the post office…

Come on, you may say. For a guy who rarely pays over $50 for a vintage receiver, how could you possibly justify that kind of financial and time commitment–?

Well, let’s think of it this way.  I remember when when I paid well over two thousand for my first laptop in college. How much is it worth now? Maybe twenty dollars–?

Many people have retirement funds in investments, some of which are in a variety of innovative companies that they actually patronize–for example, Apple or Microsoft.  But how often can you find an investment that you can actually play with? One which you can turn on, tune in, work the controls, and enjoy?

Yes, I’m sure this is just the sort of justification voiced by many a vintage car collector…So, why not for a museum-worthy radio? After all, they’re not making these anymore.

I expect this Halli will not only hold its value, but will probably increase in value over time.

Ah, well; fun to ponder.  My question to you: Would you buy a $5,500 vintage receiver if you had it to spare?

If your answer is yes, and you do have the money, then you might want to contact Jeremy.

I’m very curious if there are any SX-88 owners among our readership? If so, please comment with your thoughts about the ’88!

And for the rest of us, just so we can revel in the vicarious pleasure of ownership, I’ve included some additional information about the Hallicrafters SX-88 below, including two videos.

Chris’ Retro Review of the Radio Shack DX-397 (Sangean SG-622)

SangeanSG-622SWLing Post reader, Chris Freitas, has sent me a link to a recent review he made of the RadioShack DX-397.

I know many of us have had one of these little analog radios (branded as RadioShack or the original Sangean SG-622) at some point.

Chris has fond memories of the DX-397. Click here to read his review.

 

Reader Survey: Comparing the Tecsun PL-680 and PL-660 on medium wave (AM)

Tecsun-PL-680-MW

[Update: Please note that this survey has been closed, but the audio samples–labeled Radio A and Radio B–will remain to allow others the opportunity to make an evaluation prior to reading the PL-680 review.]

[Update 2: The PL-680 review and readers’ survey results have now been posted! Check it out here.]

The results from the PL-680/PL-660 reader surveys (here and here) have been pouring in! As of this posting, well over 200 readers have participated by listening to and evaluating the two receiver comparison surveys. Thank you!

Yesterday evening, I spent time comparing the Tecsun PL-660 and PL-680 with medium wave reception in mind. I recorded dozens of samples and picked four broadcast recordings I felt best represented receiver performance. Note that this will be my final survey before I post the PL-680 review later this week.

If you’re not familiar with these readers surveys, please read our first post, as it contains all of the vital info and disclaimers.

To participate in this survey, start by simply listening, then fill out the form that follows with your choice of “Best Radio” for each broadcast. All of these medium wave samples were recorded in the evening hours, which I believe is more indicative of receiver sensitivity, selectivity and AGC. Notice that I indicate distance to target station (as the crow flies).

Catching a USAF HF-GCS transmission in Morocco

My buddy, @K7al_L3afta (on Twitter), posted this interesting recording of the US Air Force High Frequency Global Communications System on 15,016 kHz USB at 18:01 UTC yesterday:

HF-GCS-logoI don’t believe I’ve ever heard or noticed this type of USAF HF-GCS transmission before.  Sounds almost like a numbers station.

Update: SWLing Post reader, Daniele, comments:

It’s an EAM, “Emergency Action Message”:

Thanks, Daniele!

As I’ve mentioned before, @K7al_L3afta lives in an urban area of Morocco and his shortwave radio listening is plagued with radio interference (RFI). Still, he seems to snag some interesting catches on the shortwaves just like this one which he said he caught by “turning the tuning knob randomly.”

Serendipity is, indeed, the best type of SWLing!

Reader Survey: Comparing the Tecsun PL-680 and PL-660 synchronous detection

PL-680-Sync-Detector

[Update: Please note that this survey has been closed, but the audio samples–labeled Radio A and Radio B–will remain to allow others the opportunity to make an evaluation prior to reading the PL-680 review.]

[Update 2: The PL-680 review and readers’ survey results have now been posted! Check it out here.]

The results from the PL-680/PL-660 reader survey have been pouring in! As of this posting, over 160 readers have participated by listening to and evaluating the AM shortwave audio samples. Thank you!

This morning, I spent time comparing the Tecsun PL-660 and PL-680 with synchronous detection in mind. Time permitting, I hope to publish at least a medium wave audio survey, too, before I post the PL-680 review later this week.   I doubt I will post an SSB reception survey since my digital recorder injects a bit of noise into those recordings.

If you’re not familiar with these readers surveys, please read our previous post, as it contains all of the vital info and disclaimers.

To participate in this survey, start by simply listening, then fill out the form that follows with your choice of “Best Radio” for each broadcast. Please note that I include two recordings per broadcast, but ask that you choose the best radio overall for each broadcast.

For example: if you feel that Radio A is better in the first recording of Radio Australia, but Radio B is slightly better in the second recording (again, of Radio Australia), you still need to chose which radio is best overall in the Radio Australia recordings set.

You’ll note that signal stability varies between the two recordings; this is simply the nature of shortwave radio. Also note that each recording was made within one minute of the other in each set.


 Audio Samples

Radio Australia 9,580 kHz

ABC-Radio-AustraliaBelow I’ve provided two recordings of Radio Australia on 9,580 kHz. In both recordings, I have the PL-660 and PL-680 in normal AM mode for the first half of the recording–you will hear a het (hetrodyne–which sounds like a high-pitch tone) in the upper sideband. About halfway through the recording, I switch each radio into lower sideband sync, which effectively removes the het sound.

I have provided two recordings for each radio since QSB (fading) was fast and deep. Indeed, you’ll note in the second set of recordings that the radios had more difficulty maintaining the sync lock.

First Recording: Radio A

First Recording: Radio B

Second Recording: Radio A

Second Recording: Radio B

Radio Riyadh 17,615 kHz

Saudi-Arabia - Radio-RiyhadRadio Riyadh could certainly be considered weak-signal listening this morning, though their opening on 16 meters was quite good for the time of day.

In the recordings below, I start in AM mode, then switch the radio to USB sync after 15 seconds, and to LSB sync after 30 seconds.

In the first set of recordings both radio’s filters are set wide; in the second set, narrow.

First Recording: Radio A – (wide band filter)

First Recording: Radio B – (wide band filter)

Second Recording: Radio A – (narrow band filter)

Second Recording: Radio B – (narrow band filter)

RadioShack liquidation sales

RadioShack-StoreClosing-2

One of my local RadioShack stores is closing and liquidating all of the merchandise and store fixtures. I’ve visited the store twice and found that the best bargains come from the components cases where everything was marked at least 70% off.

RadioShack-Components

I purchased about $60 worth of components like those above: test leads, connectors, plugs, adapters, RG-58 cables, fuses, breadboards, etc. Two packs of PL-259 crimp on connectors, for example, were about 70 cents each. Those prices are much better than you would find at a good hamfest; so I stocked up!

Several of you have commented about your local RS deals as well–SWLing Post reader, Troy, writes:

The Radio Shack® Digital Recorder you blogged about a few months back is marked down to $2.98 at Radio Shack stores – if it can be found. I drove 43-miles one way to buy one today. Despite gas and a $3 highway toll, I’m happy.

Radio Shack online inventory has historically been abysmal and given that stores are closing I’d encourage your readers to call stores – even if stock is listed as unavailable.

I haven’t tested it yet but from a previous post it appears software can convert the audio from mono to stereo. I’m sure I can figure it out with my MacBook Pro, but if not – given the modest expenditure – I’m satisfied nonetheless.

RadioShack-StoreClosing Many thanks, Troy!

If you are interested in snagging deals, you should act now. There is very little left in my local store and, according to a district manager I spoke with, items are moving as quickly in other regional stores. From reader reports, this is the case across the country.

Keep in mind: not all RadioShack stores are closing. Many franchise and corporate stores will remain open, at least for the time being.
