I'm in the market for a scope. I have never used one. I'm ready to get one and learn. What's a good one that could be used by a 1st timer? Looking to see modulation on my radios. I can put an ok tune on my radios but without a scope it's really just by ear and guess. I know a scope is not a...

I have an echomax 2000 desk mic. This is really a great mic. I'm not a fan of echo at all. Having said that, I still believe this is the best desk top mic I have ever owned. I will use just a tad of delay, but never echo. The locals here that like echo have been begging me for this mic for...

As I become more and more hands on with my radios, I seem to be be accumulating a pile of stuff that I can't come up with a good idea to keep it all organized. I'm talking about small wires, compacitors, soldering tools, and just miscellaneous stuff that's involved with tinkering with these...

I was unable to find that box, I did however talk to a tech that knew about it from the guy I got it from. It did have 24 volt pills in it, it also had 2 step up 12 to 24 transformers. He is an older guy and his memory is not that great, he wasn't 100% sure on the numbers only sure that it did...

Just got a few radios from ebay. One was trashed because of these parts. I know they are noise toys. I understand there is only one way to tell what they do or say. But there are 4 with 3 different types. Anyone ever seen these or have an idea what they are? If I throw them away without know...

That's a great idea but that's not what I'm wanting to do. There are alot easier ways for me to do what your talking about. I don't need a hand held radio, ebay or a rubber ducky antenna.

I would also be limited to the recive bandwidth of a small cheap handheld radio, correct? Im playing with wide banded tx.

I have s-400 running my bench mobile for 3 years. It's in panty hose and I clean it off every now and again. It works flawlessly. It has a fan but never hear it come on. I also have 2 s-700, don't have any complaints at all. Been running them for about 6 months. When un use they draw about 85...

Going to make this my weekend project. If I can over pay for parts at radio shack. I have a stryker 655, the talk back circuit in that radio will make any mic sound great. Only one I have every seen that you can use a d104 with. Once I realized that, I leaned about talk back being what it is.

I'm not sure what it's called.these are the keys words you may have missed... I'm guess an rf sample is not what's needed to use head phones. Is it called demodulator? Basically I want to hear my over the air audio without being pinched by the receive bandwidth of another radio. I don't feel...

Thanks alot guys, I'm looking to just hok up head phones for now. At some point I will get into using a scope before the antenna and understand that's a different can of worms

I have read a few times on this forum that you can take magnet wire and wrap around your coax and then use head phones. I need a "dumimes guide" on how to make this. Here are the questions I have. 1. How many wraps and where do you put it on at? 2. Do you just put a female jack on the wire...

I'm sorry to have have gotten this thread so off topic. Until I find that box and can post some pictures it's all a guess or theories. I never really ran that box because it was so odd.There were some things in there I didn't recognize from other boxes. I understand some of Ohm's law and I know...

Thanks your input, I do understand I=v/r. I Also know this is not a magical box. I need to find that box and see what's inside. It's a very larger box, not knowing what's inside makes this point moot. My shop is fed with 120/240v single phase. I have a box that allows me to run 3 phase...

Its a very odd box, I have tested this box on a few different meters, power supplies and antenna. I don't run the box at all just something I got from a flea market. In theory it should not work like it does. I'll have to look to see if I can find that box and post some pictures. I remember...

Rf watts divided by DC volts equals DC amps? Edit; I ask because I have a little home brew 4 pill that does 650 to 750w at 14.0v on a 32 amp regulated power supply. I have had this checked on other stations and PS with same results.

Thanks so much. I have one on the way. It's 250k 5 watt potentiometer. Again Thanks

I have the ts350 vhd, I love this amp. Before I knew what I was doing a few years back(and yesterday) I drove this amp with a 50 watt radio. Now I use it as a driver for dx and just ssb. I did how ever lose the potentiometer just this week and am hoping to get that replaced as soon as I fine...

The attached pic is the pot from a texas star dx 350 vhd. This one no longer works. I need to find a replacement but am have a hard time finding one. I don't know if this is oem or something else. I'd really like to put the same type back in as this amp has been great for many years. Can anyone...

Yes I will do the whole as I said in the above post. Again as I side in the above I really wanted to know what c104 was for with in the radio. I know the radio has a rx issue, just want to know if this is the cap that created issue
