5/8 has to have a good ground plane. I'd guess you're not getting it even with the radials. Do you have an analyzer

I know your field pattern and efficiency changes when you have more than one resonant antenna on a vehicle. What happens if you have a main tx/rx antenna dead center of the roof and another rx antenna 8 inches away? Both are the same type of cb mag mount antenna.

In the house I am using a 1/4 wave 6meter groundplane. In the vehicle I'm using a mag mount antenna behind another mag mount antenna. I cant find any info on using it in a mobile situation so I'm trying and learning. I have nodded the box a little. I had to ground the 3 rehostats, moved the...

Same light generating the noise, except I'm in the mobile. Local station on am.

Qrm eliminator on the bench. Pretuned it for the lul in signal. On ssb talking to some locals. I turned on a lamp that creates the interference. Purpose of this one is to show the difference in the interference as well the effect on the station I was listening to. Upcoming video of the unit...

Anyone tried or noticed a difference in keying activation wattage when using a different size cap to sample the rf?

I like my ubitx. I put mine in an old cb base gutted. Added a gel cell 12v battery inside. It's my power fail radio and fun qrp. Its actually impressive for what it is

Had a big long review wrote out. It disappeared. Just watch the video

We have tons of noise in town. Led lights, billboards and god know what else. Up to a 9+ in front of various stores. So my wonder was if anyone had tried the phasing qrm eliminator out in a mobile setup? I'm thinking about trying it this weekend.

Dang it man.

So out of these outfits, is there one I can make a line drawing for and they would do the pcb lay out? I'm not familiar with laying out parts on a board. Point to point is all I've ever done.

It's just point to point and all in my head. I've not laid out anything for board format yet wires and parts everywhere. Itll fit on a 3x3 single layer board prob.

Outta currosity, have you had them assemble the board or just had them make the board

I'm looking for a manufacturer that will burn small quantity pcb's and help lay it out for a project. Anyone ever used anyone for that?

I realize that. I'm just wondering if it would help make a better one.

I've been thinking about something. Yeah o think about a bunch of stuff all the ti e. What are the possibility that you could add a chain or a real antistatic ground strap to your car. Would adding that and making a better ground from the car to the real earth make the ground plane work better...

Trimag mount, 10,20,40,75 meter hamsticks. Didnt play with it much tet but yes it got close to tuned. Atu did the rest. Gonna work in it more later

After ssb and 40ch was lined out, what was left? The pll changed the game but other than digitizing like some imports what's left on the old designs to add? FM? Smt components have changed the ability to do much, processors have locked us into specific channels, parts so pitiful you cant peak...

Looking at it some more and thinking about it, it's just a dipole. Any gains they claim wouldve been from having a matching ground section where the automobile might or might not have a good enough match. That's all I see. Not that it's a terrible idea or anything but if the car is a good...

It's just an idea in process. Dont laugh too hard. If I get it working I'll change materials and atatchment of course. Ultimately it might just be a cloud warmer. Just dunno yet
