Sangean ATS-909X2: Uli is seeking information about firmware version 78

Many thanks to SWLing Post contributor, Uli (DK5ZU), who writes:

Hi Thomas,

I hope you are fine! I just bought a Sangean ATS-909X2 despite of the mixed reviews it earned in the beginning. There are a lot of reviews as on SWLING and other sources. But I think no newer models have been reviewed.

Mine is build in May 2022 and has a firmware version 078. This is quite ahead of the reviewed versions with 073. Unfortunately, I cannot find any information throughout the net, what changes where made since the version 073.

I just have the radio for one day, but for example the noise when touching the display is gone and I found no birdies so far. The SSB is still low concerning the audio level compared to AM but the SSB sounds much better as on my Tecsun 501x I had once.

As of now, I am really happy with this rig, and if current production line and firmware fixed some issues of the older one’s I guess this should be known since there may be folks interested in the radio which do hesitate to buy one because of the probably outdated reviews.

Do you know a source, where a firmware update log could be found? I just found this:

But this one ends with version 073.

Would you mind to post this question on the blog?
If you need more infos please let me know.

Best regards and 73,

Post readers: If you can share a link to firmware revision logs or any information regarding the latest firmware updates for the ATS-909X2, please comment!


Sangean America Notes in our comments:

[S]oftware version 0.78 is a compatibility update for the new LCD hardware in the ATS-909×2 this update is only for units that use the new BU91510KV LCD display. it does not improve the performance of the ATS-909×2

Guest Post: Comparing the Reuter Pocket and the Icom IC-705 from an SWL’s perspective

SWL with a Reuter Pocket and the Icom IC-705

by Uli (DK5ZU)

Some time ago I asked how the IC-705 performs on longwave and I got some great feedback. Thanks a lot again. Since the HAM bug bit me again, I wanted to do SWL and HAM Radio portable with one rig. I started with SWL some weeks ago (just before the bug bit). I acquired a second hand Reuter Pocket RDR 51 Version B2. It is a standalone SDR Receiver 0 … 30 MHz / 50 ..71 MHz, and in my B2 version it has also FM (Stereo/RDS) and Digital Audio Broadcasting (DAB). You may find the detailed specs here:

The Reuter Pocket could, at one point, be configured as an QRP Transceiver, but it is no longer supported. There is a new RDR 52 small tabletop models, which can be ordered as a transceiver, too. But due to Covid related supply chain problems and price changes for the components, the new model is currently postponed.

The IC-705 is available, though. And for portable HAM operations it is a no brainer; obviously with a high price tag, but comparable with a new Reuter RDR 52 tabletop. And since my budget for the hobby is limited, I thought about funding part of the IC-705 price by selling the Reuter Pocket. But I wanted to do a side-by-side comparison so I ordered the 705 and was able to check them both on one antenna. The goal was to compare their sensitivity and selectivity on the lower bands: BC on AM and HAM bands for SSB. I did not compare CW since I am not a CW operator.

The antenna is a MiniWhip from PA0RDT which works quite well on the lower bands.

This comparison is not at all scientific and reflects just my opinion and what I heard. But anyway, there may be some people out there interested in this. So much for the intro.

Let’s start with my overall findings. Continue reading

Uli asks: “How well does the Icom IC-705 receiver work on longwave?”

Hello Thomas,

I started to enjoy BCL and SWL some week ago (again). I have a HAM license for many years, but was QRT for the past few years. Now, the HAM bug bit somehow again and I’ve been listening to the bands via a Tecsun H-501 but changed this one to a Reuter Pocket already.

The Reuter Pocket (Source: Reuter)

The Pocket is a really great receiver including also the FM Bands and the popular (in Europe) Digital Broadcasting DAB.

Still, it is just a receiver. So for now I am searching for a new rig, too. The current offerings are all tempting, FT-DX 10, FT-991A, IC-7300, IC-705 and so on. I really like the new models due to their features, and most due to their displays. My former rig was a Yaesu FT-897.

I already read your and the other reviews of the IC-705 (especially the BC receiving parts) and it could replace the Reuter in many ways. I am just a little bit reluctant because I like the longwave band a lot (we still have stations here) and there is no info to find anywhere how it works below 500kHz. MW seems to be on par with most other receivers.

Do you have an idea about a source of information concerning the capabilities of the IC-705 below 500kHz?

All the best and 73,

Great question, Uli. I’m hoping that some of our European IC-705 owners may be able to help you here. Although I’ve spent a lot of time on mediumwave with the IC-705, I’ve done little exploring of longwave. 

Please comment if you have thoughts on the IC-705’s longwave performance!
