Update: Eton Elite Satellit expected Q4 with pre-order price of $349 US

35 Replies

Universal Radio has posted a product page for the new Eton Elite Satellit.

Pre-Order

As they have done in the past, Universal is offering a “pre-order” discounted price of $349.95 that will not be charged to the buyer until the unit actually ships.

Availability

Universal expects the Elite Satellit to ship sometime in the 4th Quarter of 2019.

I gather the Elite Satellit is still very much in the design and development stage, so I would even take the expected availability date with a grain of salt. Much may depend on how well the initial prototypes perform in evaluations. With that said, I’m sure Eton will do all they can to have the Elite Satellit ready for the 2019 holiday season.

Not a hoax–!

I’ve gotten a number of emails and comments from readers asking if the Elite Satellit is a hoax. I can assure you it is not. 🙂

I get why so many are skeptical, though. It’s not often that a legacy receiver–one that’s been off the market for nearly a decade–is re-introduced with an identical chassis, and with the promise of some internal upgrades. In fact, I can’t think of a time this has happened in the past.

Features and Specifications

All we know about the Elite Satellit is what is mentioned in Universal’s product description:

The Eton Elite Satellit is simply the finest full-sized portable in the world. The Elite Satellit is an elegant confluence of performance, features and capabilities. The look, feel and finish of this radio is superb. The solid, quality feel is second to none. The digitally synthesized, dual conversion shortwave tuner covers all long wave, mediums wave (AM) and shortwave frequencies. HD Radio improves audio fidelity and adds additional programming without a subscription fee. Adjacent frequency interference can be minimized or eliminated with a choice of three bandwidths [7.0, 4.0, 2.5 kHz]. The sideband selectable Synchronous AM Detector further minimizes adjacent frequency interference and reduces fading distortion of AM signals. IF Passband Tuning is yet another advanced feature that functions in AM and SSB modes to reject interference. AGC is selectable at fast or slow. High dynamic range permits the detection of weak signals in the presence of strong signals. All this coupled with great sensitivity will bring in stations from every part of the globe. Organizing your stations is facilitated by 500 user programmable presets with alpha labeling, plus 1200 user definable country memories, for a total of 1700 presets. You can tune this radio many ways such as: direct shortwave band entry, direct frequency entry, up-down tuning and scanning. Plus you can tune the bands with the good old fashioned tuning knob (that has new fashioned variable-rate tuning). There is also a dual-event programmable timer. Whether you are listening to AM, shortwave, FM or FM-HD, you will experience superior audio quality via a bridged type audio amplifier, large built in speaker and continuous bass and treble tone controls. RDS is included. Stereo line-level output is provided for recording or routing the audio into another device such as a home stereo. The absolutely stunning LCD has 4 levels of backlighting and instantly shows you the complete status of your radio.

Many receiver parameters such as AM step, FM coverage, beep, kHz/MHz entry etc., can be set to your personal taste via the preference menu. The Elite Satellit has a built in telescopic antenna for AM, shortwave and FM reception. Additionally there is a switchable antenna jack (PAL male) for an external antenna. Universal will offer antenna jack adapters.

This radio comes with a protective carry bag and AC adapter or may be operated from four D cells (not included). The Eton Elite Satellit is for world explorers who want to travel first class.

I agree with Post contributor Guy Atkins: the Elite Satellit appears to be based on the Eton E1 analog circuitry. Guy points to three clues in this recent comment:

Exact same three I.F. bandwidths as on the E1 (7.0, 4.0, 2.5 kHz). If this is a DSP radio, why only these three bandwidths?

Selectable sideband synchronous AM detector, as found in the E1. I’m not aware of any SiLabs chips that can provide *selectable* sidebands on sync AM.

I.F. passband shift control. Again, this is not a feature in any consumer DSP radio I know of.

Of course, all of the specifications Universal has published are “preliminary and subject to change.”

As I mentioned in a previous post, you can count on us to review the Elite Satellit as soon as it’s available.

New indoor passive loop antenna for shortwave

20 Replies

Many thanks to SWLing Post contributor, Dave Zantow (N9EWO), who notes:

Here is an interesting looking indoor passive HF loop antenna [photo above] that Randy McIntosh just started selling in the US. Made in Greece. Model TLA500C. Sorry it’s not for MW.

Here’ are the specifications/description from the eBay page:

This sale is for an HF magnetic loop antenna that should be attractive to anyone living in an apartment, residence, or other location where it is not possible to erect an outside dipole antenna. If you can erect an outside antenna, this is always the best solution for reception as no inside antenna can compete with a good outside antenna for the very best signal reception. But erecting an outside antenna is not always possible for many people desiring to listen to amateur radio or shortwave signals. Thus, this antenna offers a solution to such hobbyists handicapped by personal physical limitations to mount an outside antenna, minimal yard space to erect such an antenna, apartment living, or HOA restrictions.

This antenna spans a tuning range spanning 3.5 MHz through 40 MHz and thus covers 80 – 10 meters on the amateur radio bands, all international shortwave bands plus the 11 meter CB bands. The antenna comes with a 3′ coaxial cable to attach the antenna BNC output to a SO-259/PL-259 input of your receiver (most receivers).

Simple assembly directions are also included and you may be view this information in the last picture at the top of this listing. If you have a different input on your receiver other than the PL-259, you will need to acquire the proper interconnect cable from another Ebay seller. Assembly takes 5-10 minutes using only a proper sized Phillips head screwdriver and the antenna can be disassembled to transport to a remote DX location or for convenience in your travel luggage…..or as our picture shows, located permanently at your home listening room or bedside. Depending upon your preference and the dimensions of your receiver, the antenna can be set on top of or next to your receiver (see pictures at the top of this listing) during operation. Please remember that this is a “receive only” antenna and cannot be used to transmit signals.

Features:

non amplified….no batteries required

works on wide variety of communications receivers both stationary or portable

light weight aluminum construction weighs about 1 lb with the interconnect cable

portable – can be disassembled and folded into a low stature for compact transport

sharp tuning helps filter strong non-desired out-of-band signals

low noise loop design helps filter RF noise often found inside a home or apartment from lighting or appliances

tuning range of 3.5 MHz – 40 MHz

small loop antenna assembles to 18″ diameter at the broadest point

great alternative for signal reception when an outside antenna is not possible

very easy set up and connection

Thanks for the tip, Dave! This looks like a practical design for portable and low-profile operation.

Since it is passive antenna design, I image you would have to re-tune the antenna for peak performance each time you shift frequencies. It looks like the control panel would make this a pretty simple process.

Post readers: If anyone has used this antenna, please comment with your impressions or contact me with your review.

Wow! Check out the new Eton Elite Satellit!

Many thanks to SWLing Post contributor, Brent Levit, who notes a new Eton receiver in the latest Universal Radio print catalog: the Eton Elite Satellit.

Click to enlarge.

Raise your hand if you see the similarities between the Elite Satellit and the famous Eton E1 (photo below)?

The Eton E1-XM

Brent also notes:

“Universal Radio has a $399.00 price tag. It also states in the catalog that it would be available late summer 2019.”

Brent, thank you for the tip and thanks for snapping that photo.

UPDATE: Brent just shared the following photo of the product page.

Hamvention Highlights: The Polar Explorer 500 watt transmitter

The Polar Explorer

Compared to others, the Polar Explorer booth at the 2019 Hamvention was quite modest. As you can see in Polex Technology photo [at the top of this page], they only had an Elecraft KX3, a laptop, and their Polar Explorer on the table.

So what is the Polar Explorer exactly?

At first blush, the Polar Explorer looks like a 500 watt amplifier, but then you notice that it has both a microphone and key connected directly to it. The Polar Explorer also has a color backlit screen/display–and the one at the 2019 Hamention was attached to an Elecraft KX3 QRP Transceiver.

Turns out the Polar Explorer isn’t an amplifier at all–it’s an external 500 watt transmitter. As noted on the Polar Explorer website:

The Polar Explorer is a breakthrough in transmitter design which brings much higher efficiency to SSB and CW transmitters. Most ‘linear’ amplifiers run at around 55 to 60% efficiency, which means a lot of extra power supply capacity is required, along with extra cooling and dissipation capacity. By increasing efficiency, The Polar Explorer significantly reduces power supply requirements as well as cooling. From this, significant reductions in cost, size, and weight can be realized for a given power output level.

[…]The Polar Explorer interfaces to your transceiver using the CAT interface to obtain frequency and mode information. It automatically follows the transceiver as you QSY or change modes. Your transceiver never transmits; The Polar Explorer handles those functions, and includes a T/R relay to protect your transceiver.

By connecting your transceiver to the Polar Explorer, you’re essentially bypassing and delegating the transmitter portion of your transceiver to it. Your transceiver still provides the receiver section and full interface/user experience–the Polar Explorer provides the muscle.

Note that the Polar Explorer is a project in development. I know that at least initially it has been designed to interface with the Elecraft KX3, but I imagine additional compatible transceivers will be added in due time.

At the 2019 Hamvention, the company was seeking beta testers that would be willing to pay for the Polar Explorer–essentially in kit form–at cost. If all goes well, they hope to finish all beta testing by the end of the year and potentially start production in early 2020.

As for the price, I don’t think they have a firm number yet, so I would either contact them directly or watch their website for updates.

If you’re interested in becoming a beta tester or learning more about the Polar Explorer, I encourage you to check out the Polex Technologies website!

Tecsun PL-990 and S-9900: A few facts about the new Tecsun radios

16 Replies

Yesterday, we posted a photo of a Tecsun S-9900 “prototype” that was shared by @katsu3_uc on Twitter:

Screenshot of katsu’s tweet with translation by Google.

Shortly thereafter, another image was shared featuring the Tecsun PL-990:

To put this in perspective: there hasn’t been a new product announcement like this from Tecsun since the appearance of the S-8800 nearly four years ago–!

This buzz created a flurry of emails to me in only a few hours.

Readers wanted more information and details about the new radios and, frankly, I wanted to confirm what details we could infer from the photos. I only knew that there would be a “high-performance” receiver introduced this year, but knew very little other than that–I certainly didn’t expect two radios in the works.

So I reached out to a trusted source and now have some solid information I’ll share below:

The Tecsun PL-990

Yes, the Tecsun PL-990 is real. The image above is a correct representation of the working prototype.

There is no official launch date yet, but if all goes well with production and testing, the export version will become available in December 2019 at the earliest. It’s highly unlikely it will ship prior to December–it’s more likely it could ship sometime in early 2020.

The Tecsun “S-9900”

There is a new model in development, but the anticipated design and model number are not as shown in the picture above. When @katsu3_uc corrected his initial post and clarified that the radio in the photo was only a prototype, this was correct. I believe this was one from many years ago.

There are few details about this radio as it is in the early stages of design/development.

Production, availability, and other product details are simply not available yet. I get the impression the chance of it shipping this year are very low.

Stay tuned…

As I learn more about these two Tecsun receivers, I’ll post updates here on the SWLing Post. I’ll tag updates with model numbers (Tecsun PL-990 and Tecsun S-9900) so posts can be read in chronological order. Note that even though “S-9900” will not be the model number of the second receiver, I’ll use it until we have the new model number.

Of course, I’ll review both radios as soon as they’re ready for evaluation!

The Tecsun PL-990: The next full-featured portable?

19 Replies

[Update: Please check out this post about the Tecsun PL-990.]

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following image originally posted in the Shortwave Radio Listener Appreciation Facebook group:

This looks like a solid iteration of the venerable Tecsun PL-880.

While the previous photo we posted via Twitter user @katsu3_uc of the Tecsun S-9900 looks like a departure from Tecsun ascetics, and more like the classic Grundig Sattelit 700 chassis, the PL-990 image is much more of what I would have expected. The S-9900 is much harder to believe.

I will try to gather more information about these designs and if one or both might come to fruition this year. I’ll post PL-990 updates with the tag: Tecsun PL-990.
