Since you are an RF engineer, what would be better in this video which was so terrifying (to you) ? We are curious of your input for the sake of continuous improvement. Thanks, that'd be appreciated ;)

I was really hoping the “RF engineer” would have replied with something more helpful other than a hit-and-run comment. Oh well.

I suggest using some 00 steel wool to buff the surface of the brass before soldering. A little buff on the center conductor of the SO239 as well. I find it helps the solder adhere more securely. Edit: Brass often has a light layer of oxidation which can inhibit the soldering process. Also, using steel wool to prep PCB surfaces for soldering helps with kit building.

I like the all parts you need in a box before you start... I always spend half my time looking for stuff midway through a build. Nice video Ape and looks/works well great build

The in & out markings of the 7805 voltage regulator in the schematic are the wrong away around.!!! 73's de LA3EQ -Jan

The name stomp box comes from their useage as guitar effect boxes. I have noted while the Chinese boxes follow Hammond part numbers they do not always follow the sizings. Specifically the boxes are frequently shallower than the original, which is why the SO239's did not fit well. I took a slightly different tack and cut/filed the 4 hole flange down to a 2 hole flange similar to the 239 found on IC-7300's. Had you sourced the parts from Digikey, Mouser or the like you could have picked the correct components as specified while at the same time helping out local manufactures and suppliers.

Thanks for the video! I was looking for such a power divider for other uses, and this was spot on! I was curious if you had done a sweep of the SWR on the input and output ports? I would do that if I build mine, just to see if there are any 'bumps along the way'...

You know Jeff, I don't think I did and that's a great idea.

Hi Ape, Great build and video. As soon as I saw the size of that box, I would have used a two hole chassis connector or a bulkhead connector. I also think a piece of single sided circuit board could be used instead of the brass strip, or even a piece of 14 or 12 gauge wire across the connectors. You and the family stay safe. 73 WJ3U

I see no one commented on why the boxes are called "stomp boxes". It is because guitar effects pedals are housed in these type of boxes. You have to "stomp" the button on the top to initiate the effect. Hope that helps.

It would be nice to see how it works in real life. It's one thing to look good on an analyzer but very different in actual use. Does it make the audio clearer is the true test. 👍

This device will allow the operator to adjust the mic gain up to the point just before the RF signal begins to flat top on the scope. In that sense, audio can be clearer for having used it. 73, kc4i

I wish you had also measured the input SWR with a 50 ohm dummy load on the output.

Fair point, sorry about that 👍

Good point. I always make sure my solder is "dry" before moving on. LOL You know as a builder myself I gotta rib ya a little. Serious question. With my lack of knowledge with inductors, since the brass plate is the inductor, does thickness of the brass matter and is it part of the calibration? Or is surface area what determines the amount if inductance introduced into the circuit. Hence the measurement of 1X1.5?

@TheSmokinApe

Ай бұрын

Hey BlueGoose, I would imagine that both size and thickness play a role 👍

Why add the brass plate? Does it have a purpose other than as a buss? Wouldn’t a 12 ga. Copper wire running between the center pins of the so-239 sockets, with the resistor leads soldered to it do the same thing?

@TheSmokinApe

I am under the impression, which may be incorrect that the brass plate acts as an inductor. Without the plate we would need to add a toroid.
