I know it may be teaching you to suck eggs but have you tried it with the mike disconnected in case it's a problem with the mike?

He's a machinist, not an electronics engineer. And doing what you ask could double the time it takes to make one and for him would increase his risk of claims for damage if he makes a poor job of wiring it up. Unlike you he has access to the sales information for how many people will ask for the...

Marconi 2955B Radio Test Set will do everything you need in a single box.

People don't use magmounts in keydown competitions because other than the reasons mentioned that they're not rated for the power a fixed mount provides a much better connection to the RF ground. The more efficient the RF ground the more current can flow in your antenna and the stronger signal...

President Grant II, UK/EU President McKinley. Both on US frequencies as they're the same as the EU ones, both do 4W AM/FM, 12W SSB out of the box.

So much stupid having it adjust both RX and TX together with the one control. If you have it so your clarifier alters your TX as well as RX then when you adjust your clarifier to receive them better your TX frequency changes. So they then end up adjusting their clarifier so you sound better to...

You've a lack of RF ground so bad that the antenna system is even having to use the mic cable to compensate. Using mirror mounts you effectively don't have one as it's the horizontal metal directly under the antenna that counts. When you have an adequate RF ground it doesn't matter what you do...

You're assuming there's a problem. Currently the solar reports have A index at 12 but more importantly K index is at 4 with a noise floor of S3-S4. So with the K index that high it's going to be like HF has been turned off so you're not going to be hearing much more than local but you'll have a...

20Hz makes no difference on SSB. You can't guarantee listening on other radios to guess the accuracy. Also the only way to do it for SSB if you are is to use a radio with a temperature controlled oscillator for receiving and to use a tone of a known frequency transmitted into the microphone of...

The reason for the difference is the fact that the magmount is using capacitive coupling to ground, the trunk mount isn't. When you're using capacitive coupling you'll never achieve X=0 because there will always be some element of reactance.

None of them worth listening to when it comes to antenna systems if that's what they're saying. Whilst there are situations where it's necessary to have coax of specific lengths or you can take advantage of the characteristics of coax being specific lengths a single end fed monopole mobile...

Beg, borrow or buy an antenna analyser to see what's going on - you can get cheap NanoVNA ones for under $50. If you've a very good RF ground you can find that because manufacturers make antenna lengths assuming it'll be installed with a crap RF ground like the majority are, that it's actually...

For what purpose? We're looking for a RF ground, not a DC ground. The battery negative plays absolutely no role in that. You don't even need to have the antenna mounted on the same vehicle to provide a decent ground, you could have a magmount on the roof of the car parked next to you and it...

Absolutely. I drive semis here in the UK and we close couple our trailers with usually no more than 3ft from the back of the cab to the headboard of the trailer. DAF and Volvo put the factory CB antenna mounts on the back of the cab and you have all hell on trying to tune them if you're pulling...

DC multimeters are of little to no use for testing antennas due to the fact AC/RF doesn't work like DC and what may appear to be a dead short to DC isn't to AC/RF.

You've two different antennas. The vertical one will give great performance on local contacts. The inverted V will be utterly crap for local contacts as it'll be horizontally polarised so will be as much as 20dB or almost 7 S points down on the vertical. However for DX things change a bit...

Spaceweather.com "Earth-directed solar flare and halo cme (coronal mass ejection) This morning, an explosion on the sun hurled a CME almost directly toward Earth. It's called a 'halo CME' because the storm cloud appears to make a halo around the solar disk as it moves in our direction. Minor to...

Coming from a country where FM was the only legal mode from 1981 to 2014 it's been mildly hilarious watching all the rubbish and scaremongering that's been going on since the announcement was made.
