PantronX Titus II DRM receiver: HFCC posts “pre-order” form

titus 2 big

Many thanks to SWLing Post contributor, Aaron Kuhn, who writes:

The HFCC is now collecting “pre-orders” (really expressions of interest in purchasing/demand) for the PantronX Titus II Android Radio at http://hfcc.org/delivery/receivers.phtml

“The purpose of this form is to collect the information on the demand for pre-production samples of the Titus II receiver.

It is NOT BINDING and it does not establish any contract. The ordering party is not obliged to buy the indicated quantity and the supplier is not obliged to deliver it.

Availability: Pre-production batch – 4Q/2016, regular production – 1Q/2017.

Price: Under 100USD plus shipping and local duty/taxes not included.

Payment methods: Wire transfer for larger quantities, PayPal works too, but the buyers would need to add PayPal bank fees.

You will be contacted on the specified e-mail address and asked for a binding order when the exact price and available delivery method is known.”

As Aaron also noted, though the HFCC posted this, the pre-order request form appears to be published by the manufacturer. I’m sure this is a way PantronX can gauge market interest and also decide what first-run production numbers should look like.

Thanks again for the tip, Aaron!

Advice using the RTL-SDR on the Mac OS operating system?

RTL-SDR-RTL2832U-e1471375714199

Many thanks to SWLing Post contributor, Gary Wise (W4EEY), who writes:

A good friend of mine recently bought an RTL-SDR (Version 3) from Amazon after seeing the unit in action at my house.

He primarily uses Apple computers, however, and the software selections for Apple’s IOS recommended at the RTL-SDR Quick Start Guide (http://www.rtl-sdr.com/rtl-sdr-quick-start-guide/) don’t install easily (I understand they refuse to install due to security issues or restrictions).

What could you or your readers recommend for my friend (doesn’t have to be free)?

Thanks for sharing your question, Gary. I would also love to know a way to use my MacBook Air with the new RTL-SDR without having to run a dual-boot of Windows.

Earlier this year, Chris Smolinski, developed an easier way to run the RTL-SDR on a Mac, but I’m not sure if it can take advantage of the new HF coverage. Has anyone tried?

Readers: please comment if you have suggestions for Gary or if you’ve successfully used the new RTL-SDR on a Mac OSX.

SDRplay RSP now only $129 in the US

Many thanks to SWLing Post contributor, Mike Hansgen (K8RAT), who shares the following message from SDRplay:

Monday September 12th

Thanks to the weakening of the GB Pound, the dollar exchange rate has changed significantly over the past few months. We have decided that we would like to pass on the benefit of this to our customers and so have reduced the price for which we sell the RSP to those customers who buy directly from us in US Dollars down to $129.

Thanks for the tip, Mike! That’s a fantastic price for the SDRplay RSP which, I believe, was already a good value at $149 US. Click here to purchase the RSP directly from SDRplay.

Update: HRO have also adjusted their RSP pricing to $129 US.

South American shortwave catches, rarely heard in Europe

RCRI

r9djHi there, I thought I would share some DX catches, all of which are rarely reported in Europe and yet I was fortunate enough to catch in Oxford UK, using a couple of different set-ups. The first is Radio Chaski Red Integridad from Urubamba Cusco, Peru, heard using an Elad FDM DUO and Wellbrook ALA1530 active loop antenna (indoors). The two subsequent receptions originate from Brazil; Radio 9 de Julho, Sao Paulo and Radio Transmundial,Santa-maria rtmCamobi, both of which were caught using the venerable Sony ICF-2001D portable receiver and my 200 metre longwire antenna. In all three cases, persistence was necessary whilst optimum conditions of propagation aligned with my listening schedule at home and my less frequent, but regular DX’peditions.

I am soon to deploy a 200 metre Beverage with adjustable termination resistance for nulling ‘rearward’ signals and matching transformers suitable for 75 and 50 Ohm receiver antenna inputs. I hope this will further improve my reception capability on both the MW and SW bands.  Another post specific to that project is in the pipeline, but in the meantime, thanks for reading/ watching and I wish you all very good DX.

London Shortwave’s portable “spectrum capture lab”

SWLing Post contributor, London Shortwave, just posted a photo of his portable SDR setup on Twitter and noted:

LondonShortwave-Portable-SDR

“Portable spectrum capture lab back in operation. Grabbing the grey line hour on the 49 mb. Listening to Radio Fana!”

Wow!  I love this go kit!

Looks like London Shortwave is running an AirSpy with Spyverter via SDR# on his Windows tablet.

Having played a lot of radio in the field, I think what’s great about this setup is the fact it’s all contained and properly laid-out inside the padded case. Simply open the case, deploy an antenna, and you’re in business! With all components inside the case, there’s much less chance a connector, battery, cable or SDR will be left in the field accidently. Quick deployment and quick pack-up time; that’s what it’s all about!

Great job, London Shortwave! I’m happy to see you’re back in the park capturing spectrum and logging DX!
