Cross Country Wireless have just released a HF Upconverter. This will allow HF or VHF SDR receivers such as the RTLSDR dongles, Funcube or our own SDR-4+ receiver to work on HF, LF and VLF.

Unlike other upconverters currently available we have added the RF protection features from our SDR-4+ receiver including an antenna isolation transformer and RF over-power protection. This protects the SDR receiver or dongle and the attached PC from damage caused by static electricity charges on the antenna or nearby high power transmitters.

There are two versions of the Upconverter. One has a 125 MHz local oscillator and the frequency range is 12 kHz to 45 MHz. This is intended for use with the RTLSDR and Funcube dongles.

The other version has a 10 MHz local oscillator and is designed for use with the SDR-4+. This has a frequency range of 12 kHz to 1.6 MHz.

Here are some of the specifications Cross Country Wireless  has published for the HF Upconverter:

Technical data – 125 MHz version for RTLSDR and Funcube dongles

  • Frequency range: 12 kHz to 45 MHz
  • Input impedance: 50 ohms
  • IF rejection: > 60 dB
  • Local oscillator frequency: 125 MHz
  • Local oscillator level at antenna socket: < -50 dBm
  • Gain: -6 dB
  • RF connectors: SMA female
  • Power connector: USB B

Technical data – 10 MHz version for SDR-4+ receiver

  • Frequency range: 12 kHz to 1.6 MHz
  • Input impedance: 50 ohms
  • IF rejection: >100 dB
  • Local oscillator frequency: 10 MHz
  • Local oscillator level at antenna socket: < -60 dBm
  • >Gain: -6 dB
  • RF connectors: SMA female
  • Power connector: USB B

Also, from CCW on YouTube:

“This is a video of a Cross Country Wireless HF Upconverter used with a CCW SDR-4+ receiver to listen to VLF and LF transmissions using a half wave dipole cut for the 80m amateur band.”

There are 20 second samples of the following stations:

  • BBC Radio 5 Live on 693 kHz AM
  • BBC Radio 4 on 198 kHz AM
  • GYN2 Skelton on 81 kHz FSK
  • MSF Anthorn on 60 kHz time signal
  • GQD Anthorn on 22.1 kHz Anthorn
  • GQD Anthorn on 19.6 kHz

This version of the Upcoverter uses a 10 MHz local oscillator so the frequency displayed is 10 MHz higher than that received i.e. 10.693 MHz = 0.693 MHz = 693 kHz.

Dietmar compares the Tecsun PL-310ET to the Icom R-71A

“I recently saw a YouTube video that demonstrated that the new Tecsun PL-310ET has better reception than the previous PL-310 that you reviewed [see video below].

I purchased the PL-310ET for $50 (incl. shipping) from Anon-Co and received it from Hong Kong in less than two weeks. Anon listed the PL-310ET as their #1 selling item at the time of purchase (PL-660 was #3).

The PL-310ET now has the very useful ETM. I am quite impressed with the radio’s reception. Basically, I could listen to the same radio stations that I could get with my 20+ year old ICOM R-71A. However, the Tecsun’s sound quality was considerably better. The ICOM had a slight edge with interfering stations in a few cases.

When comparing radios, I used the Tecsun with its telescope antenna and the ICOM with an indoor Palomar shortwave loop antenna with range from 5000 KHz to approx. 17000 kHz.

The PL-310ET also has external antenna input and can charge NiMH batteries.

I consider the Tecsun a great bargain considering what I once paid for the ICOM.”

Many thanks for your thoughts on the PL-310ET, Dietmar! I may just pull the trigger on a new PL-310ET. Perhaps it could replace my PL-380 as a travel radio. I’m curious if its dimensions are any smaller than the PL-380 and if it mutes between frequencies when band scanning.

Anyone else have thoughts about the PL-310ET?

I believe this is the comparison video Dietmar was referencing:

The ShouYu SY-DP-330: a retro, x-bass shortwave radio

shouyu-dp330

The Professor recently sent me a link to the ShouYu SY-DP-330–stating it must be the “big brother” of the ShouYu SY-X5. Indeed it is! The DP-330 sports all of the features found in the SY-X5. It is very large in comparison, though, and runs on four D batteries. The DP-330 even comes with a remote control–most likely for the built-in MP3 player.

On a side note, the DP-330 is in the only shortwave radio advert I’ve ever seen that also features a giant mega-mechanical monster robot. Classy!

Do any readers have the DP-330? Please share your comments.

Global Tuners for Android smart phones

GlobalTunersAppMany thanks to Chris Freitas, who informed me that the excellent Global Tuners website, has produced an app for Android-based smart phones. With this app and a free Global Tuners account, your smart phone can remotely control a number of  receivers across the globe.

Best of all?  It’s free!

Click here to view Global Tuners in Google Play.

You won’t find the app through categorical searches via your phone–you must search for the term “Global Tuners” in the Google Play. Indeed, this app has been available since 2012, but none of my categorical searches had ever unearthed it.

To my knowledge, there is no Global Tuners app for iPhones/iPads as of yet (iOS).

The Tecsun ICR-110 packs AM/FM and digital recording/playback

In a comment, SWLing Post reader Owl mentions:

“Tecsun has just released ICR-110 which is as BIG as the PL-880 and seems to have the same speaker too.”

The ICR-110 can be found on eBay–click here to search. At $46.00 US shipped, I’m very tempted to purchase it. Though it lacks shortwave, it appears that it can record AM (MW) and FM broadcast stations in either MP3 or WAV formats. While I’ve yet to find a radio that can make a digital recording with acceptable fidelity (the CC Witness Plus being a notable exception) I would like to think the engineers at Tecsun have nailed it.

I have a friend who has recently purchased the ICR-110, and am looking forward to his review! (hint, hint)

TuneIn adds the Shortwave Radio Audio Archive

IMG_0135
I’m pleased to announce that TuneIn Radio has added our Shortwave Radio Audio Archive (SRAA) podcast as a new Internet streaming broadcaster.

For those of you not familiar, TuneIn’s website and mobile apps offer the user the ability to listen to streaming audio of thousands of radio networks and radio stations worldwide, including AM, FM, HD, LP, digital, Internet stations and podcasts. Check out this post from 2012 where we review TuneIn.

TuneInLogoWhy stream shortwave radio recordings?

While most international broadcasters can be streamed directly via TuneIn or via the broadcaster’s website, listening to the shortwave archive will make your computer, smart phone or Wi-Fi radio sound like a proper shortwave radio–you’ll hear all of the noises, fading, ionosounders and things that go “bump” over the ether.

So if you like the low-fi sonic texture of shortwave radio (ahem, I do!) add the Shortwave Radio Audio Archive to your favorites on TuneIn Radio.

Chorus 4: The DSP chip that supports AM, FM, DAB, DAB+, HD Radio and DRM

FrontierSiliconThe London-based digital solutions company, Frontier Silicon, has announced a new DSP radio chip that offers a wide array of available modes and is even DRM ready.

I have seen no specifications for this chip yet, and do not know if it covers the shortwave radio spectrum.

Still, this might be the perfect chip to allow radio manufactures to design an inexpensive, fully digital product in countries where digital platforms are gaining strength (anywhere from the UK to India, for example).

Many thanks to Rob De Santos for apprising me of this. I’ll post the specifications when they become available. Read the full press release below:
