Many thanks to SWLing Post contributor, Dan Robinson, who shares a radio comparison he initially posted in the excellent Extreme Shortwave Listening Facebook group. Dan writes:
When the Sangean ATS-909X was first released a few years ago, I decided that I would hold off obtaining one to let whatever bugs there might be in production get worked out.
I have always been impressed by the design of the 909X, but was cautious when it came to the question of overall sensitivity. I once owned the 909, had it modified by Radio Labs, but that seemed not to do much — the 909, in my view, suffered too much from the well-known deafness issue when using the whip antenna.
Over the years, I used and still own many of the classic portables. This includes the SONY 7600GR, Grundig SAT 500/700, 2010, E-1, SONY SW100/SW07, SONY SW-55, and the radio I consider to be at or near the top of the small portable heap, the Pan RF-B65. But a couple of weeks ago, I broke down and bid for a new in box Sangean 909X. It’s the black version, and arrived a couple of days ago.
I remain impressed by the 909X’s design — beautiful radio, wonderful large LCD and backlight, excellent filtering, along with a feature we used to see in the SONY’s — adjustable/variable attenuation. But I wondered how the 909X would stack up against two of my favorites, the SW-07 and RF-B65. I was crossing my fingers — but alas, initial results are not encouraging.
While the radio initially on its own seems to be quite sensitive, I lined it up next to the SW-07 and RF-B65 and did a comparison. Now, first I must note that propagation continues to be in the dumpster and I conducted this test in late afternoon.
All three receivers were tuned to Cuba on 11,760 khz — they were located next to one another on a table in the top level of my home here in Maryland. The results are seen in the video below.
You can hear how much more clearly the SW-07 and especially the RF-B65 handle a signal. With the Panasonic, stations just pop. Same with the SW-07.
Disappointingly, as you can hear, stations on the 909X appear to be buried in noise. It’s quite extraordinary — I was very surprised by this comparison and intend to perform additional side-by-side tests in different areas of my home, which does suffer from high noise levels likely produced by electric lines and a transformer outside (which is why a run a Wellbrook on my main radio stack downstairs). But it is notable that the 909X appears to struggle so, while the old classic portables SW-07 and B65 excel. Interested in the views of others . . .
Dan, this is very similar to my experience with the Sangean ATS-909X.
Like you, I absolutely love the design of the 909X–the large display, tuning wheel, front-facing speaker, ergonomics–but was pretty disappointed when I pitted it against three other (less expensive) portables on the shortwave bands.
I know the 909X performs much better when connected to an external antenna. I’ve also learned that fresh batteries are a must as the 909X’s sensitivity is directly related to supplying optimal voltage. I know, though, that you had fresh batteries in your 909X, Dan.
Again, many thanks for sharing your comparison.
