Another review of the Tecsun S-8800

6 Replies

UPDATE: Click here to read our full review of the re-engineered Tecsun S-8800. Note that the review below refers to a first production run S-8800e model.

In reply to our Tecsun S-8800e overview, SWLing Post contributor, Hymefly, comments:

I own this radio. Its performance on AM and shortwave is better than my Kaito 1103 and Sangean ATS-909x. My Grundig Satellit 750 beats it on SW. The 8800 is a bit better on AM than the 750, though.

The 8800 and my GE Super Radio 1 are just about equal on AM. The 8800 beats my Panasonic RF-2200 on SW, but not on AM. I didn’t compare it to my other radios on FM, as I really don’t listen to that band nor have any interest in it.

I did try out the FM band, though. It seems to have good sensitivity. The speaker provides good sound quality, but not “Super Radio” good. Display looks outdated. Not a fan of those amber/yellowish displays with spotty screen coverage. Not even close to the display on my 909x. But then again, no other radio comes close to the 909x’s display. Why can’t manufacturers implement nice bright white lit displays like the 909x?

The remote works ok. By the way, all comparisons were done utilizing each radios’ own built-in AM and telescopic antennas for SW. Overall, I can compare it more closely to the RF-2200, but with 8800 having slightly less sensitivity on AM and better on SW. The two even look almost the same. The 8800 seems to be an updated and refined modern design borrowed from the RF-2200. The RF-2200 has a more robust solid built, though. Overall, I give the 8800 a score of 7.5 [out of 10].

Thank you for your input, Hymefly. I’m pretty impressed the new S-8800 even comes close to the performance of the Super Radio 1 and the Panasonic RF-2200. I’m very curious what the price will be when the S-8800 hits eBay.

A Replacement Whip Antenna for Sony ICF-SW7600G

The Sony ICF-SW7600G (Photo: Universal Radio)

This is a guest-post by Eric, WD8RIF.

I’ve had my Sony ICF-SW7600G for almost twenty years. Early on, my very young son broke the receiver’s telescoping whip antenna and it was a simple and inexpensive matter to order a replacement whip assembly from Universal Radio, the Sony dealer from whom I had purchased the radio.

Recently, the receiver’s antenna failed at the pivot-point. First, the factory-supplied countersunk screw’s Phillips-head stripped out through repeated attempts to tighten the pivot over the years until finally I had to replace the screw. The best replacement screw I could find was a 2mm x 6 Allen-head screw from an R/C hobby shop that appeared to work fine until I managed to strip the antenna’s threads through over-tightening this screw. (Perhaps the Allen wrench simply provided too much torque for such a small screw.)

Clearly, it was time to actually buy a replacement antenna. This turned out to be easier said than done. Universal Radio is no longer a Sony distributor and has no access to parts for Sony products. A visit to the Sony website disclosed that service-parts are handled by two other companies, neither of which could provide the antenna—a surprising thing to discover since I think the antenna used in the ICF-SW7600G is the same part which is used in the current-model ICF-SW7600GR. A search on Amazon disclosed a seller offering the part for over $52, far more than I wanted to pay. Perhaps belatedly, I thought to check eBay where I found several listings, some offering the genuine Sony part shipped directly from Japan. I was intrigued, however, in the listing by stone_deng (link) who offered a non-OEM replacement antenna, shipped from Virginia, for $16.80 with free shipping. The description claimed the antenna was a perfect-fit replacement. Figuring the price would make this a good gamble, and because I wouldn’t have to wait weeks for delivery from Japan, I placed an order for one on a Monday evening and the postman delivered the antenna to my mailbox the following Friday. (I noticed as I was composing this post that stone_deng has raised the price for this antenna to $19.90 with free shipping.)

In comparing the replacement antenna with my original Sony part, the only difference I could see is that the metal tip of the replacement antenna is of a different style. Dimension-wise, the two antennas appeared to be identical.

Installation of the new antenna was simple. A single screw secures the antenna to the radio.

Remove this screw and pull the antenna straight out of the receiver.

It should be possible to slip the new antenna into the hole, twisting it to properly line up the mounting-flange, and run the screw back into place. In my case, the new antenna insisted on snagging on something inside the radio and I ended up removing the rear-panel entirely to install the new antenna rather than try to force the antenna into place. Fortunately, the rear panel is easily removed.

Remove the battery-cover and the four AA cells. Remove the five black Phillips-head screws that are marked on the rear panel with arrows. The rear panel will then lift straight up. Insert the new antenna into its hole, lining up the mounting flange with the screw-hole, and insert and tighten the screw. Carefully place the rear panel into place, lining up the four screw holes, and insert and tighten the five screws. Re-insert the AA cells and replace the battery cover.

I’m hopeful that this non-OEM antenna will prove to be rugged but time will tell. If this antenna proves to be inferior than the original in some way, I will post a follow-up to this post.

Obligatory disclaimer: I don’t know stone_deng, and I don’t have any financial interest in his company or products.

TECSUN S-8800e availability in Europe and Bertrand’s first impressions

13 Replies

Many thanks to SWLing Post contributor, Bertrand Stehle (F6GYY), who writes:

Hi Thomas,

The new SSB portable receiver TECSUN S-8800 has been available from Germany, since the beginning of 2017.

Supplier:https://www.wellenjagd.com/ has the S-8800e, a Europeen version.

I have one unit here and also being an owner of the PL-880, [I would describe it as] a better PL-880 with more features.

DSP filters on SSB: 0.5 – 1.2 – 2.3 – 3.0 and 4.0 kHz

DSP Filters on AM: 2.3 – 3.0 – 4.0 and 6.0 kHz

Long telescoping Antenna L = 92 cm

BNC Antenna socket

AM External antenna (500 Ohm ) on panel….with an internal /external antenna switch.

Main and fine tuning [much] like the PL-880 , but all metallic buttons, bigger and of better quality.

VFO main tuning knob is large and has a good feeling.
Line out is stereo ( 2 channels ) L and R
Separate bass and treble control
2X LiH Batteries 18650 ( no external power supply possible, no 12V socket). Batteries can be charged while the rx st still in use.

On this S-8800e–my first impressions:

Very sensitive on longwave… ( PL-880 was not )

Very good copy of ssb stations

RX does not get so quickly overloaded as the PL-880 does…

Quite bigger than the PL-880 => 27 cm X 17 cm, about 7cm thick.

Wow–many thanks for sharing your first impressions, Bertrand!

I’ve been waiting quite a while for the S-8800 to be released. I will have one on order soon and will do some comparisons with the PL-880 and PL-660.

As you discover more about this receiver, please share your impressions with us!

Anyone else have the S-8800? Please comment!

Cold War radio treasure trove: The CIA Freedom of Information Act Reading room

Many thanks to SWLing Post contributor, Alexander (DL4NO), who writes:

I just found a German reference to the CIA Freedom of Information Act Reading room

https://www.cia.gov/library/readingroom/

As a first test I searched for “radio design”. A few of the documents found:

ACTIVITIES OF AMATEUR RADIO DESIGNERS

JPRS ID: 8744 TRANSLATION ELECTROMAGNETIC SHIELDING DESIGN FOR RADIO-ELECTRONIC EQUIPMENT

DOSO INSTRUCTION FOR AMATEUR RADIO OPERATORS; BULGARIAN RADIO EQUIPMENT PRODUCTION

AIRCRAFT RADIO COMMUNICATIONS IN THE USSR

This could be an amazing source, especially of historical information from the Eastern Block. But expect any search to be real work: Only the title and some classification of the documents are searchable. The rest is scanned documents.

Very cool–thanks for sharing, Alexander. I spent a little time this morning browsing the results using various radio-related search strings. It is a very deep archive.

Letter from former District Manager at Radio Australia Shepparton

2 Replies

Many thanks to SWLing Post contributor, London Shortwave, who shares the following letter by Gary Baker, former district manager at Radio Australia, Shepparton–published in the Shepparton News. Here’s an excerpt:

Recently I heard that the HF radio transmission site at Shepparton, known as Radio Australia, is to be shut down.

[…]I understand the ABC needs to cut back on some services it provides and make use of the latest technology. This makes sense except in the case of the Shepparton facility.The Shepparton transmission site has the capability to direct radio signals into specific countries as we see fit.

This is unique to this site, as no other site can reach the countries this one can.

In my time as district manager at the Shepparton site, I recall some instances where the Shepparton site was called upon to direct radio signals to specific targets.

At one point the Fiji Government shut down the local Australian ABC transmitter.

Shepparton sent radio into that country to keep Australians informed during that time.

When there was a coup in the Solomon Islands, once again we sent signals into that country.

We also sent radio signals into Myanmar at the request of the Australian Government.

Another task that the Shepparton site fulfils is to send signals into northern Australia in times of need, for example during Cyclone Larry when the Northern Territory radio service was beamed back to the tropical north from Shepparton.

The Shepparton site is in a location that has good weather and is politically stable.

This makes it an ideal tool for widespread information broadcasting.

The ABC would argue that this HF radio service is old technology and can be replaced by the internet or satellite services.

This is true.

However, the ABC and the Federal Government do not control the internet or satellite services in other countries and therefore they are not reliable.

HF radio broadcasting from a secure location is very reliable.[…]

The diminutive but brilliant Sony ICF-SW100: a few autumn/winter DX catches

10 Replies

Hi there, I posted an article on this brilliant little radio a few months ago because it had demonstrated a level of performance way beyond my expectations. Notwithstanding it’s incredibly small size the DX results I obtained with it were beyond my ICF-SW55 and up there with the iconic ICF-2001D. Armed with synchronous detection, selectable side bands, SSB, CW and sensitivity seemingly boyond it’s tiny form factor I can’t recommend this radio highly enough.

Originally introduced into the market in 1993 and discontinued in 2005, the ICF-SW100 won’t ever be repeated – a point I made in my original post, but of course they are available on eBay and prices remain robust for what is now essentially a vintage receiver. Unfortunately, I don’t get to use my ICF-SW100 very much as I have various other receivers and have been involved in antenna building/testing and MW DX for the past few months. However, on the couple of occasions when I have taken the Sony on a mini DXpedition, it’s resulted in some fine DX. As demonstrated in the examples below, Mali, Guinea, Alaska and Japan are amongst the more difficult signals to copy in Europe and yet the ICF-SW100 delivered them! Text links to reception videos on the Oxford Shortwave Log YouTube channel follow below and futher down you will find embedded videos. Thanks for reading/watching/listening and I wish you all great DX!
