Sangean ats 909 speaker replacement
Hello folks. Shipping in the US is free. The speaker requires replacement if the volume of your receiver is low and the audio distorted with a crackling or buzzing sound. Radio Shack no longer carries this specific replacement anymore, but I have a limited quantity of replacement speakers from a different source. These speakers are manufactured by a different company with the same dimensions and audio characteristics of the original speaker.

Cost effective base speaker for Sangean ATS-909/Radio Shack DX-398
Hello radio enthusiasts. Well, I recently purchased another SDR to add to my gear. Black Friday sales significantly brought the price range of these devices very close together. I used a 25 foot, indoor, longwire antenna with 3 feet of RG coax terminated to a SMA female connector. Frequencies used were in the HF band in the early evening and late afternoon.
SFI was about 85 during the tests. It's frequency coverage is 1KHz to 2GHz. Installation of the drivers and SDRuno software were really easy.
I had the RSP1A up and running in about 15 minutes. Datasheet link here. Frequency coverage is KHz to 1. Driver installation and software installation were not quite as smooth as SDRplay, but it wasn't too bad with the excellent tutorials online. Both units were configured with medium AGC and full use of the internal RF amplification available in the software settings.
It was refreshing to see more range above and below the LO. You may ask why only 8 MHz displayed instead of 10 MHz? I did not see or hear many signals coming through the noise floor. The V3 displayed 2. I was able to tune and listen to a few stations easily. I was a bit puzzled by the RSP1A and reduced the bandwidth down to 3 Mhz bandwidth for better comparison. I could hear DX stations on both devices, but the audio was more intelligible on the V3. This is where things became more comparable between the devices and performance was similar.
The RSP1A had problems pulling out intelligible signals in or near the noise floor. Another observation was the audible noise between the two devices. I found some information on SDRplay's forum from others who experienced the same issue. I did not find a good technical response or resolution to the issue. The RSP1A shines in this area because SDRuno automatically selects the appropriate filters to reduce overloading and interference while tuning.
AM bleed-over to HF bands is a problem with the V3 due to lack of selectable filters. The RSP1A is housed in a plastic box with some "metallic" spray covering the inside. It did not perform well when I moved a laptop power brick near it as I saw numerous spurious signals on the bandscope. Why it's not include with the product baffles me. It also has USB filtering to reject interference.
My laptop power brick had little effect on the SDR displaying only a couple spikes on the bandscope. There is no need to purchase a separate USB cable for typical installations. The RSP1A appears to lack heat dissipation as there are no heatsinks on the processor or other components.
I don't know if it is needed and did not notice any substantial drift or performance issues during the test. That is an absolute NO from me!. I don't see what all the praise is about. I do understand the out-of-box experience is a little better with the RSP1A, but that doesn't seem to be enough reason to buy it.
Using Direct sampling of the V3 produced rather impressive results too. The SDRuno software interface is not as user-friendly as it could be. It offers an extensive array of settings for the tinkering mind to spend hours tweaking and fiddling which is great. I found the workspaces thing to be a pain in the butt.
I did not like the taskbar littered with several open windows. New versions are coming out frequently to address the numerous bugs in the software so I am happy to see an active development community for their product. HDSDR is a very simple out-of-box installation as well. It just works with only minor tinkering. It is more user friendly than SDRuno for a new or casual user. The performance of both SDRs was about the same. Maybe another review in the future?
I wanted to share a little update with you. I am still working on projects and have a few radios in for repair. Most of it came to a halt as my beloved Tektronix scope is on the fritz. I had to change focus to repairing the scope 5V power rail had a short and waiting for parts. I also picked up another NanoVNA to have some fun with.
This VNA will be used with custom firmware and see if we can make some interesting projects out of it. You will see a review soon. I have a couple shortwave receivers here to repair and an Icom transceiver. I will try to share some updates as time permits over the holidays. Speaking of the holidays; our radio club held the annual Christmas party tonight.
It was a bit different than previous years due to Rona and was hosted over a virtual video conference. It was fun nonetheless. Of course, many of you also remember the movie, Frequency and a subsequent TV series. The classic story of Brett and Charlotte as they try to save their foot tower in the worst windstorm to hit Georgia since the Civil War.

Ham operator finds his radio can time warp and talk to his dad decades in the past. How does he expect to QSL? Female ham operator Jodie Foster controls the Arecibo radiotelescope, where she picks up an extraterrestrial signal.
Now that's what I call DX. I picked up a broken Tecsun PL from a customer who no longer wanted the radio. Here is the story and result. The radio was owned by a ham radio operator who used it as a bedside companion. He said that it fell off the nightstand one day and crashed on the floor while a Tecsun ANX antenna was connected at the time of the crash.
It damaged the connector and possibly some other components. He attempted to repair the antenna jack using a home brew method and said the radio never worked right afterwards. He reported that AM and Shortwave band reception was flaky and the tuning encoder wasn't working well either.
The radio arrived a week later and I put a fresh in. Powered up and tuned FM stations just fine. Switched to AM and shortwave - it was completely deaf. Normally the strongest AM station in town is able to come through on a crystal radio set, but not the Tecsun. The tuning knob was erratic and seemed to jump two steps or not do anything at all while tuning.
Touching the tuning knob increased static to the radio. My first look inside the radio. Notice the compressed brown wire next to the screw hole. There was a nick in the insulation from the screw.
The back of the radio case has a metal shield and pad to ground the radio to the PCB shield. Also noticed several missing screws. I powered up the radio and it was still deaf on AM and shortwave bands, but the tuning encoder works great now suspect ground short from previous owner's repair. I used my DMM, signal generator, and scope to make my way through the receiver. Immediately, I found a cracked diode in the protection circuit next to the antenna jack, I replaced it with a 1N

Return to Vintage Transistor Radio Discussions. Users browsing this forum: Google [Bot] and 5 guests. Ads are not permitted. I have the Sangean ATS portable radio that was modified a few years ago by I believe Radio Labs, to get rid of the chugging when tuning as well as increased sensitivity on AM band plus a Motorola connector in back for an outside antenna. All these mods were working fine. After turning radio off and trying to turn it back on, it starts making loud crackling noises even with Volume all way down. Was able to get radio going again, but it seems the crackling noise returns, being real loud. Tried the proper AC connector and it caused super loud humming noise!

Both have a general coverage shortwave range and have SSB, so they can be used to listen to amateur transmissions. Another interesting radio is the Tecsun PL, which I do not have. It is cheaper than the other two and it combines sync detection with a rotary tuning knob, an interesting combination. Of course, shortwave broadcasting as an information medium is all but dead in the Western world.

Nice audio effect for low pitch sound. Please clean glue remains before install the new rubber edge. Please pay attention to the size of the item before you purchase it. Handstamping metal is not an exact science.

I recently decided to replace my little portable shortwave radio, the Sangean ATS , with something better. When using the tuning knob, the sound is muted between every frequency. My main use is to tune through the amateur radio bands, so chuffing is very annoying. Getting better sensitivity and a backlight color other than puke-green were secondary wishes.
Not quite understood that you wanted to say about it.
