With our Royce dealership, the 606 and the 600 was among the early 23ch radios we sold. Except for size and features, both had similar 37Mhz crystal matrix circuits. Royce also used two transformers in their audio chain. One thing you could say about their electrical engineers, for better or...
As with most of Western NY, no special glasses were necessary. We had very heavy cloud cover all day. Except for all of the small businesses in the Buffalo area that raked in big profits, many viewers were somewhat disappointed. Nonetheless, at least for me, it still was an experience to...
I will be able to see 2m 31.3s of totality from my front yard. I usually take the dog out around that time, but I’m thinking about leaving him in the house. He doesn’t pay any attention when I turn on and off my ceiling sun :giggle:, but I fear his outside world view may be different...
This is my enhanced PDF version of this Sears radio, and the almost complete spliced version of the schematic. As you can see, only a few connections and components are missing in the gutter area of the book that didn’t get scanned.
Only after you replaced the caps or other possible components that may have caused the original transistor to burn out in the first place, would I then go with the NTE that you already purchased. It’s easy enough afterwards to test for heat with your fingers. Depending on how hard it’s being...
As replacements, I often purchase the old NTE or the ECG line of transistors. I like the sealed packages they come in. That helps avoid fakery. The pin-outs and specifications are also clearly marked on the package. In your case, an ECG294 or NTE294 should work fine.
I would replace them with a 12v warm white bayonet bulb. They’re commonly used as an automotive replacement. In doing so I would also remove the 100 ohm resistor as shown in the schematic and experiment with a much higher resistor to achieve your desired brightness. To be on the safe side I...
Gotta love those old analogue multimeters! They usually contain a selector inside that looks like something to be used in a high power antenna switch. Generally, that’s the first thing that goes bad in most modern day digital multimeters.
This is my final cleaned rendition. Unless the pages were wired together or had associated circuit boards, they were separated and orientated vertically for monitor viewing. Page 30 was missing.
I’ve been playing with my NOS Midland tester. It’s the one on right. As an example, I also included the photo of a Micronta meter. You will find a number of similar models with slight differences. Notice the batteries are still in the wrappers. While removing the back, a red tag fell out that...
I always scan in color at 600 DPI. Depending on the particular scanner or software driver, gray scale could possibly be something less than 256. Scanning in full color assures me that will never be an issue. To save on file size, the document is later converted to gray scale using a paint...
My ideal radio for truckers in particular, would have the capabilities of working on either Ch19 or some other UHF frequencies, along with some new antenna designs that will cover both. IMO It’s too tough to convince most buyers to purchase separate radios, but a single system will introduce...
