This pulling of the tuning knob job didn't help in my case. I got a new firmware release when I was in Japan. I will try to load this to the radio soon and see what has been changed.

The new firmware (v723) installed itself without problems. The volume control has a much smoother function and the steps between zero and maximum volume has been more than doubled.

It is now possible to record and playback DRM signals. Another feature that was included is the "Expert Mode" in DRM. By pressing the INFO button for >2 seconds it is now possible to display SNR and MER in dB, Mode, Bandwidth, SDC, MSC, Protection, Interleaver and Service (AAC, Mono/Stereo and the Bitrate in kbps [with 1 decimal]).

Today BBC from Moosbrunn shows a stable SNR in the 25 dB region, but REE on 9 MHz reaches only 6 -15 dB SNR. Yesterday I was surprised that REE on 13 MHz logged with >25 dB on my FRG-7700 and Dream, but hardly produced any sound on the DR111 with only 6-12 dB SNR. I have not yet found out the reason why.

It is just what the receiver did not suffice! Would you be so kind to send the firmware to my e-mail or lay out the file on any file hosting, please.

Thank you!

PCJ Media Network Plus Review the Newstar DR111

I find myself disagreeing with many points of that review. Not that the radio is perfect by any stretch, but my experiences have been significantly different (clearly, much better).

I'm not sure this release of firmware is out for all users yet, also the review doesn't chime with my experience, i.e mine has been much better

I agree with about half of the critical interview, but I certainly don't agree with the criticism that the DR111 isn't as sensitive as a $20 analog SW receiver. I say "balderdash" to the latter assertion. In spite of its quirks, Newstar's DR111 is serviceable as a DRM receiver. IMO, it's a little overpriced as a retail price of $100 would be more rational. All in all, I like Newstar's DR111.

I listened to that interview today, and this Victor guy apparently living in Sri Lanka is saying that he has some problems hearing AIR with his x-thousand dollar Perseus receiver and Dream with his Log-periodic shortwave antenna directed to Delhi, well, then I would say the odds of listening to that transmission with the DR111 would be a problem. Not to forget, AIR mostly uses 20 kbps on their DRM transmissions, something that definitely is not the best if they want to get some listeners.

The sensitivity of the DR111 is not bad. In fact, I measured the sensitivity on the test bench on AM, and it is about 1.7 ÁV at 20 dB SINAD.

DR111 Sensitivity: http://www.omnirep.se/drm/dr111.html#am_sensitivity

The DR111 happily plays BBC, REE, RUVR, RRI VoN, AIR and TDP here in the livingroom using the whip antenna. The SNR values increase when I use an external antenna, but that was expected anyway...

As for the tuning, let's wait and see what Newstar comes up with next. After all, tuning the Morphy Richards wasn't that simple either.

This sums up my experience though TDP is not as strong in the uk.
Its the best consumer receiver that has been produced to date

Just now around 2035 UTC I caught RNZI on 13.730 MHz on the DR111 with an SNR around 8-11 dB and no sound. This on the whip antenna in the livingroom.

The FRG-7700 and an external active antenna shows an average 12 dB SNR - and no audio. The Doppler is about 1.3 Hz, and that means according to my experience that no audio decoding is possible. Under 1 Hz, yes maybe, but above - no.

The distance from my QTH to Rangitaiki is about 18700 km. How about that, Victor in Sri Lanka?

Another thing I just found out: While DR111 is receiving (and playing) REE on 13.720 MHz with 18-20 dB SNR, the Morphy Richards displays the Label and the date and time sometimes, when it not displays "Searching" and returns to showing the Label REE Noblejas again. And I recall that the Morphy was much more expensive.

If recent history is any indication, any firmware upgrades simply go to a select group of testers and fail to proceed to the general owner. Let's hope this unfortunate situation finally changes and quickly.
