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

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!

AM Mode: Comparing the Elecraft KX2 with the LNR Precision LD-11

My new Elecraft KX2 tuned to Radio Australia this morning.

My new Elecraft KX2 tuned to Radio Australia this morning.

I’ve only had my Elecraft KX2 since Monday evening and have been so busy, I’ve only had an hour or so to tinker with this pocket transceiver. Monday evening, before putting it on the air, I updated the KX2 firmware to the latest Beta release which includes the new AM mode.

I’ve had so many questions from readers about the KX2’s AM audio already, I thought I’d do a quick comparison with the LNR Precision LD-11.

I set the LD-11 to a bandwidth of 9.6 kHz, and the KX2 to 5 kHz: their widest AM filter settings. Keep in mind, this is not an apples-to-apples comparison, but it does showcase each radio’s potential AM audio fidelity.

I tuned both rigs to the Voice of Greece last night on 9420 kHz around 00:30 UTC. VOG’s signal was strong into North America.

I made the following recordings with my Zoom H2N digital recorder, by feeding in-line audio patched from each radio’s headphone jack. I tried to balance the audio levels between the two rigs.

Here are the results:

The Elecraft KX2 in “Delay” audio mode

Note: Some Elecraft radios have an audio effects mode which includes a “delay” function. Elecraft describes it as “a quasi-stereo effect intended to provide depth and space to the received audio.” On an AM broadcast signal, it makes it sound wider and gives it almost a stereo depth.

I think the results from both radios are impressive. Since the LD-11’s bandwidth can be widened to 9.6 kHz, strong signals like this one sound pretty amazing. In truth, I actually prefer a filter width of about 8.2 kHz on strong signals, but VOG was wide enough to justify 9.6 kHz.  I believe the LD-11 would rival many dedicated tabletop receivers.

The Elecraft KX2, in normal audio mode, sounds flatter and narrower than the LD-11 of course, but still very pleasant!  In the KX2’s “delay” audio mode, the signal sounds much wider than 5 kHz, though the effect adds a little graininess to the audio. That’s okay, though–I love having the “delay” audio option in my tool bag.

Here’s what amazes me as an SWL and ham radio operator: both of these QRP transceivers offer excellent HF broadcast listening opportunities.

Please comment! Which audio sample do you prefer? Do you like the “delay” audio effect on the KX2? Keep in mind this is only one comparison and doesn’t address sensitivity or selectivity.
