    Looking for cable mounting brackets/ties for LMR400 for siding.

    So I know I will need to drill pilot holes in advance. The siding on my current home is steel siding not vinyl and not aluminium. It is fairly thick heavy steel. It has a bark like patern. Since one of my 3 sons post college has moved back home I need to and want to put a radio by my computer...

    So anyone planing a Galium Nitride final upgrade yet?

    I do not know if it is even a thing yet but we see their yse in microwave systems, weapon systems, power bricks and audio amplifiers for hifi so just thought I would ask. This site hopped onto cheap switching mosfets like a fat kid onto the last cup cake at a birthday party. It seemed like a...

    I searched with google but found nothing. QT60-PRO/AT-5555II PRO VS Stryker 955

    So outside of power output I was woundering if anyone has done a head to head with the two radio's in terms of TX audio mostly but also all other parameters? I am never going to purchase a Stryker 955 due to price point alone. I am going to assume that the Stryker 955 has better AM audio and...

    I am telling my priest and my wife that my radio N+1 habbit is all of y'all's fault! I ordered a QT-60.

    I am a powerless victim! LOL It is a predatory practice! It is no different than KGB honey trap in occupied Berlin! LOL I ordered a QT-60. I do not need it at all! LOL....It was 20% off but it was not even a good bundle!

    So I want to build an amp with the parts I have aquired based around 4X150A but need some help.

    So I have a bunch of odd ball parts that have slowly found their way into my parts bin. I think I have some place around 10-20 4X150A mostly Jan 7034 NOS in various questionable states. About half of them are still sealed in their Eimace or Jan Packaging NOS. The rest are still sealed int he...

    Looking for clear concise head to head comparison of AT-5555 II vs K-Po 5000 DX

    Clearly the K-PO 5000 DX seems to be the wallet friendly options. It appears to be mic friendly onlike the absolutely stupid mic connector ont he AT-5555 II. Now that I have asked down to Earth practical questions that does not involve swaping in a mosfet into a Combra 29 or doing NPC-RC mod...

    Ever order parts in your cart even though you can not recall what they where for?LOL

    So I had $900+ in my RF Parts cart. I whittled it down to $174 or so. They need a save for latter button! The high dollar parts I could recall exactly what I wanted those for it is the tiny $2 and $1 transistors I had absolutely no clue why they where in the cart! Those are the parts though I...

    Top Gun MD-1 and CP1

    So again experts what makes up the CP-1 and MD-1 parts wise? What are they doing? How does it do what it is doing? Why should anyone want or not want what it is doing? Why do you like it? Why do you not like? Can it be improved upon? How can it be improved upon? Why has it been left alone and...

    So catch me up. What is going on with the CB and Export radio market?

    It seems like everything is discontinued or out of stock. If it is not an Anytone Radio it seems like everything is discontinued or out of stock. Those few things that are available are stupid expensive for what is being offered! Is this all due to Covid-19 and how badly China handled it?

    Best source for legit MB8719 PLL?

    So they are obsolete but I would like to have a few on hand for the future. I am looking for the actual ones not the RCI version. Ebay has them a dime a dozen but I am hesitant for obvious reasons. Am I am worrying about nothing with reguards to this PLL and fakes? Is there a chance the fakes...

    Possible Cheap TCXO off the shelf part to fix Galaxy RCI drift. Read Link and tell me what you think!

    So I found this while researching for an affordable TCXO mod for Galaxy radio's. It is from 2019. It seems reasonable to me but I have never tried anything like this. I am a parts swaper at best with Mouser and Digi-Key account not a real Electronic Technician! I know just enough to get myself...

    NOS Galaxy DX-979 Audio and Stability Mods?

    So I spent last night on the sight looking at past threads and downloading support documents from CB Tricks. It has not arrived yet so I have no clue if it is the older origanal bipolar design or if it is the latter mosfet design. When I know more I will report back. I do not need more rf...

    So I messed up and bought an amp with stud mount transistors. Advice?

    So I bought this amp not knowing that some of them came with stud mount transistors. I had only seen flange mount versions of this amp. I am not returning it because it works and the seller did nothing wrong. The mistake was mine and mine alone. It works but is kind of weak. So I am not...

    Anyone build an amp with NTE317 transistors?

    I recently fell into a great deal. I got 8 of them at $24 each NOS still in the plastic retail bags like you would get at electronics store back in the 1980's. Imagine you walked into your local TV repair shop/radio repair shop! You can not get MRF455's for less than $79 each. I figured I can...

    So when I go up to my mother inlaws place a convient ground plane I can just chuck ont he ground for 10-11 meter use. It will be built from stuff on hand. So probably 108" whip, some Francis 2 or 3 foot fiberglass wound antenna's as radials, some angle brackets, maybe some aluminium on a...

    So My Radioddity QT40 came with a programing cable.

    Not sure if this is the new normal but mine came with this. I have not had more time since it arrived 2 days ago to see if it comes with a software disk or anything else. In the past I thought you had to pay extra for this?

    So I serached the internet and zero Anytone Aries II video's with less than 12-15w carrier and 50 Watt pep

    So not only could I not find any video's showing the radio's modulation charteristics at low power but zero NPC video's showing modulation envelope at low power! Given that the radio tops out at 50 watts in this age of 100+ watt radios you would think someone would say " I should demonstrate...

    Slightly Outside of RF Wheel House: Transistor Adapter Idea from Adiophile Electronic Obsolete Parts

    Here is a video on youtube. It is short and has the images, idea's and links to the person developing it. I am sure at some point this idea might be benifical for RF electronic repair and home brewing many projects not only rf related. Hope this idea spurs innovation and cooperation! Cheer's!
