Those of you following the upcoming Titus II receiver will enjoy reading this interview with Mike of Pantronix. Here’s a short excerpt taken from DRMNA.info:
[DRMNA] Can you tell us a little about the process taken to develop the new receiver?
[Mike] We became aware of the need for a digital capable receiver by a visit from TWR representatives about three years ago. Having designed RF products and receivers in the past, it intrigued me that there were no low cost method to receive DRM. This began research into the problem. Initially we envisioned and designed what we call an ATU (Antenna Tuner Unit) that plugged into a ‘standard’ Android tablet. Unfortunately as time and testing proved, ready made tablets had varying problems from vendor to vendor, model to model. The decision was made about a year ago that we had to do our own Android ‘tablet’ and integrate the ATU into it. Hence the Titus II was developed.[…]
[T]he unit is quite sensitive. RNZI evenings at 17675kHz and 13730kHz can be received various places within my house with only the internal whip. REE at 9630kHz using an external ham vertical antenna was similar copy on Pappradio (with a slight edge given to the Pappradio.)
DRM Audio while adequate, seems narrow and compressed in comparison to DReaM on my PC. I verified this by switching A to B between the Newstar and the Pappradio with DReaM using my JBL headphones. I’m beginning to wonder if the DRM audio is being processed by the DSP, just like the analogue audio. The DSP in analogue is a tad too aggressive. A real bonus in analogue is the adjustable bandwidth (1-6kHz) however. That and the DSP make analogue quite enjoyable even in the crowded 49M (6MHz) band. I have been listening to BBC on 5875kHz in the early AM with armchair copy and great audio using only the whip (throughout the house).
