    You might be able to run it under DOSbox. It's pretty good for games etc, but I'm not 100% sure your serial ports etc will be emulated - you might need to go and find an old laptop for it to run on...

    You're using the wrong search parameters. Try searching for "project boxes." Here's what I got on Amazon: https://www.amazon.com/s?k=project+box&crid=EGR10ODZLXN2&sprefix=project+%2Caps%2C256&ref=nb_sb_ss_ts-doa-p_6_8 The only difference is these are mostly plastic. You can find metal ones at any of the usual electronics supply sites, Mouser, Allied, etc. Just about any project built in a metal box can also be built in a plastic one. You just can't use the box as a ground return. https://www.alliedelec.com/view/search?keyword=project%20boxes

    Sounds like a nice idea, but I cannot find anything that fits this description on EBay or Amazon for that matter. What would I search for to find such a thing? Try searching EBay for a hobby box and you will see lots of stuff, but nothing related to sheet metal working. syd

    Embarrassed, no. Frustrated, yes. To the OP, apologies for getting out of pocket. To answer the original question, there is no answer. Every vehicle is different. Every mounting technique is different. Every antenna is different. And you even didn't tell us what bands you want to operate on. It is a situation and use-dependent topic and we know nothing about the vehicle, intended bands, mount technique/location, etc. Multi-band antennas are designed to function properly on the bands they are built for, therefore, no tuner is necessary. Same thing with screwdrivers. They have a built in tuning mechanism that, in most cases, eliminates the need for a tuner. Those are the types of antennas you do not need a tuner for. If you want a single antenna, without any built-in tuning circuits (like a plain whip antenna), you can use it your tuner to get it to function OK on a few different bands. It will not work on all bands due to the high voltages (due to anti-resonance) and limitations of the tuner...

    That can happen if the center conductor of the coax is broken somewhere. When you remove the shield connection, the in-tact portion of the center conductor capacitively couples to the jacket which acts as an antenna. Take a continuity tester to the center conductor and see of there is DC conductivity.

    The holes for the meters could be cut with a hole saw that is slightly undersized, then finished with some careful work with a round or half-round file. I used to fit aircraft parts in just that manner. One thing to remember when working with sheet metal is to deburr all the sharp edges left by cutting or drilling. The parts will fit better and it also reduces the chances of cutting yourself on a rough edge.

    A nibbler could do the large holes, even if the holes are a bit wonky, they'd be covered up by the meters eventually. A "hole saw" set is useful to have, but they are always the wrong size :D K6CPO hit the nail on the head, buy a hobby box ready made and forget making one, the diecast ones are pretty R.F. tight, maybe a bit pricey, but in my experience, well worth it...

    syd replied to a thread working with sheet metal in The Junk Box
    The nibbler tool looks interesting. I might go for a small square hole punch (!" sq) because it can be used at the corners with a saw or nibbler to finish the sides.The only part of the cabinet that I find perplexing are the 2 V/A circular meter holest. A metal punch that large has to be the exact size, and even then for a punch this size it would be very expensive. Any ideas on this part? syd

    There are hand tools that can make the job easier, such as hole saws, chassis punches, and metal nibblers (for square or rectangular holes.) The bending of the metal is a bit more complicated, even if you have access to a metal brake. Allowances have to be made when making a bend. You might research YouTube for videos about building metal enclosures. Another alternative is purchasing ready-made project boxes and adding the necessary holes yourself.

    Tooling like this can be expensive to acquire but give excellent results. I have a single one of these type punches, perfect for fitting RF sockets. It may not get used a lot, but its satisfying to get good results when it does get used. There are probably different shapes available now, especially for fitting square switches etc. Not having a square punch myself, I'd drill out as much as possible and finish the square shape with files - time consuming I know, but it works...

    In the July 2021 QST magazine, page 53, there is a project that describes how to build a project in a metal box that is approximately 8"x4"x6" (w, h,d). In it there are 2 holes to mount a pair of analog V/A meters, a square hole for a power switch, and on the back of the project there is a square hole to mount a power socket and 2 holes to mount a couple of power transistors on a heat sink. I'm far from a sheet metal expert. Where does one go to learn now to do a project like this, and where does one go to find the necessary tools to do this kind of project. The article in the magazine is nice to read, but it assumes that everyone reading the article would, somehow, turn into an expert metal smith! I don't mind learning new things, but I have no clue where to go to make an attempt at fabricating a sheet metal box of this caliber. Any suggestions on this are well appreciated. 73/ wt1v

    Sounds like you could have a short somewhere on the coax lead. It might be worthwhile opening the radio and inspecting the coax socket too...

    Problem is this When I turn on radio I get not any static or receive anything. I moved my coax around and I can get it to receive. So I thought loose cable or defect at connector. so I tightened it all and now couldn't get anything unless I unscrew the coax ground then I receive. The ground on the antenna is connected to a earth ground copper rod 8' What else can I do. Is it a radio problem or antenna. I did connect my 2 meter antenna to the radio and it acted the same, center lead in I get static and connect outer sleeve and dead. This antenna is working good on my 2 meter radio. Thank You
