Another new member -- intro
I have just been approved as a member of this list and have been busy reading many of the posts to familiarize myself with it. I am not a licensed amateur radio operator but have been a SWL since high school in the Sixties. I "discovered" shortwave when my father let me fiddle with his 1936 RCA Victor 2-band consumer radio which he had purchased new. I found it in my parents' attic ca. 1990 and restored it. I own two Hallicrafters receivers--an almost-functioning S20R which I've owned for a couple of years, and an SX-28 (not an "A" model) which I've owned and used for over 30 years and which failed a couple of months ago. I intend to get both operating before long and will probably have a few questions about them for this list along the way. Looking forward to following many of the topics discussed here.

Re: 2-wire, unpolarized outlet ?
You did not read that right It is similar but not the Edison system - the one we use is SIMILAR to the Edison split DC system! A?split-phase?or?single-phase three-wire?system is a type of??distribution. It is the??(AC) equivalent of the original??three-wire??system. Its primary advantage is that, for a given capacity of a distribution system, it saves conductor material over a single-ended single-phase system.

HT-46
开云体育
Some time ago there was a topic about a frequency shift when switching from standby to transmit and a problem with the calibrate switching function for CW operation in the HT-46.
Today I ran across a service bulletin addressing this issue. Guess where?? On my website. I knew I had it somewhere, but the old gray cells sometimes don't function well. I guess I need a full re-alignment. Just in case the issue was not?resolved, here?is
the bulletin.

place and properly connected to the service entrance panel. But with the neutral coming from the power company's transformer at high resistance, which seems to have been the case, the voltages changed a few volts up or down (more than I liked) when the load inside the house changed. I'm not sure what this says about the transformer, connections, and ground on the power pole. But when the power tech tightened the connection in the neutral just below the gooseneck above our roof, the problem disappeared. 73, Maynard W6PAP On 1/7/25 02:07, don Root wrote:

Re: 2-wire, unpolarized outlet ?
开云体育Ya Jim, that or a close variation depending on where you live; the local grounding being variable with “soil” or rocks or sand. It was the neutral [grounded neutral] that was open ?so my neutral current had to go thru my ground to local earth and back 500 feet nominal to the transformer pole ground. Recall that the codes allow up to 25 ohms to local ground, so it is not much of a return wire even for a few amps.? Seeing the light bulb brightness and dim-ness was all I needed to know I had a neutral problem. Then I checked the main neutral bus? to determine that it was open somewhere outside and called the power Company.?? Of course all the outlet boxes ?washing machine, fridge, stove would ?be floating at some voltage above local mother earth too while testing one L-N load on the stove, and likely really bad if the A/C tried to start. ? ?

the neutral lead coming from the power company via the service entrance had a loose connection which the power guys fixed quickly once they arrived. 73, Maynard W6PAP On 1/6/25 03:34, don Root wrote: James, I certainly was not the one to say any topic is stupid. That is |
Re: 2-wire, unpolarized outlet ?
开云体育James, I certainly was not the one to say any topic is stupid. That is like the idea of a stupid question. What would it take to make a topic stupid? Now that you remind me, the neutral to my house went almost open, leaving 150 volts on one line when the other was loaded. There is something to think about.
