That's my radio. A J.C. Penneys 6241! I use mine for a base station. Modified to go above channel 40 and below channel 1. My clarifier is unlocked as well. I had to subscribe to yer channel to find this video. I still have the power cords for it and a D-104 to go with it. I absolutely love this radio. I am sooooo glad you did a video on my favorite radio. Yeah, I love the kick stand. I've watched this video several times and will probably watch it again and again.
I have two of those, one bought new in 1978 and the other recently from eBay. I have both power cords for each, and, no, they aren't for sale. They really are "unobtainium". Great radios, especially on sideband.
We are working on 3d printed cord end for the roadtalker an penneys ssb radio. They really are impossible to find. Most that have radios dont have cords.
Scott Edick Like what in today's technology could make this sound better? These radios are better built period. And they are sideband radios. Want extra channels? You can add them to this. Yes they don't have Bluetooth and weather radio but really ... that's hardly something anyone uses.
i agree with ya here, these radio where built with quality components and designed really good, a standard that's missing thesedays & this goes for all electronics. it's why i keep and use all my older cb's and ham radios 73' k7sce
As far as I'm concerned, today's technology is nowhere near as good or as well built as the older radios from the 70's and 80's, they use the cheapest components now whereas decades ago they used much more expensive circuitry. I own 16 radios at the moment, ALL are from no later than 1988, most are late 70's models that i got brand new back in those days, they all work even the ones i need work one such as recapping and alignments, everyone i know that has a brand new radio sounds like crap and their radios are always getting worked on where in my case my daily radio in my truck is for most of the time my mint condition Realistic TRC-427 or TRC-449 if i want SSB. Older is better, period.
does it use 36mhz feeding a Johnson Counter driving Tayloe mixers one for transmit (QSE) and one for Receive (QSD) modulating audio from a audio phase change network up to 9mhz or demodulating the 9mhz down to audio via a phase change combiner network.
+AJKandK I have used it on torroidal transformers and it never effected the enamel coating. Labels, yeah it would easily remove a sticker. Best to test it first.
I have one That has two added tongo sweches . man i need a road map . any way i have a ham liacens . but i have 10 meder radios . the fine tone well clearfier pot dont work . and the uper an d lower ssb swich works back words and i can't get it to work the 27.385 . . now i do have two sears road talker 40 . i love them . but they too are having some problem on ssb . so i like some help to get them back working right . and retrun the 981-6241 back to 11 meter or at lest work on 27.385 lower ssb . any idas
Big Al On the older Sears SSB 3677 which was also the JC Penney 6240, there is a huge difference when running off AC as the built in power supply is known to be anemic with some of them putting out just 10.5 volts. So for real power, you'll need to run these Hitachi board radios as DC and get the full juice from an external power supply and then watch your modulation and signal climb. I assume it's the same with the 6421 in this video as they are both Hitachi made with internal power supplies.
Absolutely 100% yes, having an old cap leak out it's dielectric downwards onto the circuit board can destroy the circuit traces and other components, so yes it is worth every penny as long as it's done CORRECTLY like how Mike does it.
@@mikesradiorepair hi Mike I joined patreon yesterday. Another question for ya. What do HyGain's do poorly in? Do they have exceptional receive like I've been told? Thanks, Mike. Rich Iowa
+B Blod It's attached from the RF output to ground. In case there was a surge at the antenna it would direct it to ground thereby preventing a overload at the RX input. Neon gas is inert and does not conduct until it reaches its striking voltage at which it ionizes and starts to conduct. Once the overload is gone it goes back to a open non conducting state.
does anyone have a schematic for reference use..or maybe even look inside and tell me the ic number on the pll chip..thanks..send me a notice … may 2022
