Re: Troubleshooting new build

 

There is a pair of wires that are cross connected.? They go to the center of the main board.? You said you double checked the wire so just one other thing ..That pair from the display module is the 5 Mhz into the main board.? One side of the pair is grounded.? That wiring is uniquely wired as per the instructions.
??
On mine I have over head mag florescent lamp.? I can here the noise in the radio when I turn the lamp on and off.? The audio hiss shows the audio amp is working and when I connect a long piece of wire I then hear that antenna noise.

I've been in ham radio since 1961 when I got my novice.? I have made good friends and many even from H.S. still stay in touch. This hobby always has so many new technologies to use.? In H.S. I built from scratch a 450 MHz ATV.? Only problem no one else was on on the air (near by) HI! ? My DX was across the room to my own receiver Hi.? Used a flying spot scanner for vdeo. ?many of my parts came from garbage picked TV, Radios and military surplus..Gud'Ol Days!
Good luck and good friends hang in there

Larry,

The display is working and showing freq change, I do hear audio hiss with no antenna, much antenna noise when it's connected. I'm fairly certain wither the antenna is improperly tuned or the BX needs calibrating.?

One of the things I love about this community, I received an email about 20 minutes ago from a fellow who lives about an hour from here, offered to drive down and lend me an SWR meter if I don't hear back from my local. I wish I'd got started in ham years ago.

My BX is complete and running, I get sound from the speaker/headphones, when I transmit I get measurable power out to the antenna. I do not have a SWR meter at the moment, trying to borrow one until I have some disposable income.

I have done all the checks called for in initial setup, measured amperage, etc, all nominal.

I am receiving nothing but static and when I transmit I get no responses. I figure it's one of two things:

1. Antenna improperly tuned (MFJ-1622 with a 33ft counterpoise, coil shorted to #25, whip fully extended).
2. 40M is dead in my area. Trying to get in touch with somebody in the local club to set up a test time, but so far no responses.

Is there anything else I should do/adjust/test?
