L303 is also used in the cobra 19 as L202. It is listed in the parts section as Dynascan # 0460399008. I took a look at Ken's Electronics site and saw everything but that one. It is a Toko LA series part. I think it may be listed as LA 154 but he shows no price for it so he may not have any but...

L303 and L302 both are the same and have 340012A stamped on the side of them. The parts list in the owners manual shows the same number. The caps are just regular electrolytic caps but with 3 leads like you said. Only 2 are used + and -. There are 3 of these 47mf 450v caps in the radio. If your...

Here's the scale for using 50uv = S9. This will allow you to see how linear your meter is. S9 = 50 S8 = 25 S7 = 13 S6 = 6.3 S5 = 3.2 S4 = 1.6 S3 = .79 S2 = .40 S1 = .20 (If using 100uv = S9, the output would be doubled for each). There's a lot of info like this on the web.

I think that once you reconnect R205 and disconnect D205 it will transmit.

I know this is a bit late but I just saw it. The CB Secret book had a misprint. It should be disconnect D205 not R205. If one looks at the schematic R205 has nothing to do with the clarifier. Since there will be a constant voltage on the clarifier after connecting the wire to it, the TX only...

Here's some President Washington alignment and schematics that I downloaded at one time: One is from SAMS and the other one is the original manual. Don't know why the first one is upside down.

Here is the schematic.

By the way Loctite is the brand name of the many types of thread lockers that the Henkel company sells along with other products. It seems to get used as the generic name for all thread lockers kind of like Coke, Kleenex, Vise Grips, Channelocks, Mack Truck,etc do for their type of products...

I put one in a TRC 458. The only problem was that the face plate sits so far from the chassis that the original knob won't fit back on as the new shaft is shorter than the original one. I couldn't find anyplace that sells a longer one of that exact type. I ended up taking a short piece of a Bic...

First of all caps aren't measured in ohms. They are measured in farads. You need a capacitance meter to accurately measure them. The "5" on that cap means that it is 5 pf and the NPO is it's temperature coefficient rating. If you measure it with an ohmmeter and get no reading that is good as...

I missed the fact that it was 23 channel radio. I should have read the original post better. They are still basically the same. If you have a schematic for the D201 it's probably for the VOX version. The circuit board ones are hard to come by unless you have an original. Some day I should get...

If you have a copy of the manual it has the complete alignment procedure. It does not however tell how to adjust the 2 trimmer caps under the receive board as it was printed before that revision was done to the radio along with other ones that were done. If your radio is an early D201A it will...

If you use compressed air regulate it to about 20 psi. That's what we used in the service and in most electronic shops I worked in or use the can type. To clean boards there are cleaners in spray cans such as MG Chemicals Super Wash. You can also clean them with alcohol or even wash them in a...

I have a 2950DX that lost it's output on all modes,AM ,FM and SSB. My freq. counter shows it still puts out the correct frequency on AM but there is no power. It still receives perfectly and if I whistle into it on SSB it twitches the needle on my external meter ever so slightly but there is no...
