![]() Duh! Interesting as I see all the recommendation for the beep are kind of not the best modifications. Maybe that is why the battery indicator is flashing and beeping. I also just opened up the battery compartment and found no battery. I need to read more of the txt files and references in magazine and websites I've found online. I guess there are plugs like IC's maybe that are similar to an IDE style connector going to a breadboard though used the other way around or you just use the breadboard wire tips as I see there are male and female connections using that design used. Interesting using an IC socket for those connections. Probably easier to go lower than higher frequencies from what I read. Maybe even machined instead of eched too for more accuracy? A broader range would be awesome as I was thinking filling the gaps of the Playback radio to. I'm not sure with interfacing with SDR#, Radio-Sky Spectrograph and WXTrack yet other than sound card input with scanner discriminator output and maybe sound? For the later two apps I may need to mix the signal for the higher frequencies than 1.3Ghz though I am wondering about needing a microscope also to trim the traces more calculated for the RF Engineered circuit since they do not behave like breadboard designs. That is what pointed me to this scanner and I wanted something heterodyne (I have a KTR-1665 labeled "Playback" I also want to restore and mod) and more easilier repaired/mod to refresh my soldering skills than the RTL-SDR systems I've been playing and detecting for radio direction finding and static, noise, interference and jamming with along with microphones the Mini-3 Bat Detector. I'll look into Interlibrary loans and other sources for Bill Cheeks books as well as online. Interesting, I've only read Scanners and Secret Frequencies. I was thinking interfacing with the computer for DSD+ and maybe even using like a frequency counter. then again maybe production wafer kind of dead bug style.ĭo you have or know of any references to the DOS applications? ![]() The boards are on wafer board like they are custom made and not purchased. Three wires coming off the I think Voltage regulator transistor. There is additional metal and copper lining the inside of the case cover soldered at the corners. Taped on the cover in a antistatic bag is a chip and the bag is labeled "RAM." There is a 12 PIN IC socket on the top of the case cover. There is s blue trim pot on the top of the case cover. There is a DB25 (I think at least so may be RS232) female plug on the back of the case. There are two additional toggle switches on the back of the case wired together like STSP (I'm not sure if this is correct or for an additional option). I do not notice any meter LED's unless somehow integrated with the Display. At least in Google Chrome I can find the listing and I'm not logged into eBay. ![]() I can upload if needed though am not sure on limits of number of files as I recall reading. If you click on the image for the ended item and scroll down you will find the original listing still where you can do what I described to find the photos.
