Geomagnetic Storm Predicted (G2-Class)

Credit: NOAA SWPC

Per spaceweather.com & NOAA’s Space Weather Prediction Center (SWPC):

“A high-speed stream of solar wind is approaching Earth, and NOAA forecasters say there is a 75% chance of polar geomagnetic storms when it arrives during the late hours of Dec. 4th. Periods of moderately-strong G2-class storming on Dec. 4th and 5th could send Northern Lights spilling across the Canadian border into upper-tier US states; affect shortwave radio transmissions at high latitudes; and confuse wildlife that use magnetic cues for navigation.”

The SWPC forecasts G-2 conditions starting at 2100 UT on 04 Dec and lasting through 06 UT on 05 Dec.

Though there is only a 1% chance of this G-2 causing a “radio blackout”, shortwave transmissions at higher latitudes will be affected.

Dan’s QSL signed by Miki Gurdus

Regarding our recent post about Miki Gurdus, SWLing Post contributor Dan Robinson, writes:

Went through my books and found it, the Gurdus handwritten note to me. It appears to have been during a visit he made to Washington, likely in the period I was in college 1975-1979 but could have been later during the 80’s or 90’s.

It reads: “To Dan — In Memory of a joyful day in Washington. Michael Gurdus.”

Amazing! Thank you for sharing your memories, Dan.

Keith is impressed with the Digitech AR-1780

Many thanks to SWLing Post contributor, Keith Batari, who shares the following:

I have just got the AR1780 and comparing with others I’ve had especially the PL-660 and PL-880 beats them both. Firstly the SSB does have an annoying mute when running, but the sensitivity and sound quality is fantastic, and that goes for all bands.

The airband sensitivity is also impressive with excellent squelch. Long wave sensitivity is low[…]. Tuning is without the quirks of the PL-880 and great on general coverage bands.

Headphones sound great. I’ve opened mine and the build quality is good with band trimmers and transformers.

If anyone has acquired the circuit diagram could the post it on the Google site.

If you want a radio with a lot of bang for your bucks, then look no further.

Agreed, Keith! The AR-1780 is certainly a value performer. Click here to read our comprehensive review.

I should add that while LW performance is not stellar on the AR-1780, it should suffice for LW listening in Europe, for example. The C. Crane Skywave series does not include longwave, so if you’re looking for a compact travel portable with LW service, the AR-1780 is a better bet.

I’m in the process of thinning the herd around here at the SWLing Post HQ! I have dozens of portable radios that I rarely use–many I keep solely for review comparisons and benchmarking.

I’ve always loved the PL-600, but I rarely turn it on these days. I have the PL-660, PL-680, PL-880 and a number of other similar portables for review comparisons.

I used to lug this receiver around quite a bit–somewhere in my travels I scratched the display a bit.

It doesn’t hinder the ability to read the display–not cracked, just scratched–but it’ll turn off someone looking for a perfect specimen for sure. Indeed I’m sure there are other light scratches to be found.

It comes with the original box, soft case, earphones, power supply and manual. Essentially, the full original package.

This unit, of course, works beautifully. In fact, I turned it on for the first time in a few months and check out what was on frequency! So–BONUS!–if you’re a spy, this might be your dream radio.

I want this to be a good deal for someone, so I’ll ship to the first person who offers $40 or more (not too much more, okay?). Free shipping via the USPS. Payment via PayPal.

If interested, just contact me via email.

>>>>>UPDATE: This radio has been sold! Thanks for your interest!<<<<<

I’d prefer not to ship internationally as it often involves a headache and would incur additional costs which I can’t predict. 🙂 Thanks for understanding.

All I ask is that you put this little radio on the air!

The Airspy HF+ SDR: First impressions

10 Replies

Yesterday, I received a package in the mail containing the new Airspy HF+ software defined radio receiver.

It came as a bit of a surprise.

I’ve been busy lately with humanitarian work, the radio spectrum archive, product evaluations and travels–not to mention an active family life. I had completely forgotten that about a month ago, I received a message from Airspy telling me that they had dispatched their latest SDR to me for evaluation.

This morning, I unpacked the box to find that the HF+ is a very compact, relatively dense little SDR in a metal alloy case/enclosure. I’m simply floored by the size. The case feels incredibly durable and of excellent quality.

In terms of footprint, dimensions are nearly identical to a business card. It’s about as thick as the typical USB memory stick.

The HF+ is so thin and compact compared with the Elad FDM-S2 (which is quite a compact SDR!)

Other than my RTL-SDR dongle, it’s by far the smallest SDR I’ve ever tested.

Though compact, it sports two SMA antenna inputs: one for HF, one for VHF.

The HF port is labeled as “H” and the VHF port as “V”

The Airspy HF+ uses a common micro USB for both data and power

The HF+ is the first AirSpy product I’ve ever put on the air.

I read the HF+ product description this morning while downloading SDR Sharp–it claims the HF+ is “plug and play”.

Turns out, that is no exaggeration.

In fact, the entire SDR Sharp package downloaded in seconds, installed in seconds and the only thing I had to do after opening the SDR Sharp application was select “AirSpy HF+” from the product drop down menu.

I started the application and *boom* signals all over the place!

SDR applications, in general, have become so much easier to install over the years but I believe SDR Sharp may be the quickest install I’ve ever experienced. About as easy and lightweight as the WinRadio Excalibur application. True plug and play!

I’ve had no time to properly evaluate performance–I just put this little SDR on the air.

Fortunately, propagation is cooperating this morning–I’m hearing both WWV Fort Collins and WWV Hawaii on 10 MHz. I’m really enjoying playing with the Airspy HF+ and re-familiarizing myself with SDR#. I had forgotten how responsive and intuitive the interface is–great user design.

My first impression? I’m impressed. More to come…
