Dave reviews the SDRplay RSP

SDPlay-RSP

Many thanks to my buddy, Dave Zantow (N9EWO), who writes:

My long awaited “SDRplay RSP” review is now available. My apologies for the delay. It took more time then I had planned and other issues got in the way. We also tested it with the popular DSD+ software and worked well after some troubleshooting.

I always enjoy your reviews, Dave! As you say, reviewing SDRs certainly takes more time than reviewing stand-alone receivers–especially when there are so many options for SDR applications! Like you, I feel like the SDRplay RSP offers a good value for the listener–especially at the $129 price point.

Mark’s multi-user SDR is now online

SWLing Post contributor, Mark Fahey, has just announced that his new Beaglebone-powered KiwiSDR receiver is online.  Mark notes:

Please try out my multi-user 0-30MHz SDR[.] The test system is operating from my monitoring station at Freemans Reach in south east Australia (near Sydney).

[…]The test system is fully self contained and self operating. The antenna (ALA1530S+) we are using is a magnetic loop with an impedance tracking amplifier designed and manufactured by Wellbrook Communications, Llanwrth Wells in Wales. The receiver and CPU is the result of the Kickstarter funded project “KiwiSDR” which was conceived and designed by John Seamons ex Pixar and Lucas Films.

[…]You can use Chrome, Microsoft Edge, Safari, Firefox – but Internet Explorer is not supported at this stage. Tune in on this URL…

Many thanks for sharing your KiwiSDR, Mark! Though demand has been quite high, I have managed to claim one of the four user seats on Mark’s SDR and “listen like a local.”

Mark: you’ve done a great job making a proper listening post for your remote listeners. The KiwiSDR/Wellbrook ALA1530S+ combo is performing admirably!

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 PatronX can gauge market interest and also decide what first-run production numbers should look like.

Thanks again for the tip, Aaron!
