Hello fellow HAMs, Why is the Ameritron ALS-600 more expensive than the newer ALS-600S? I'm about to pull the trigger on the 600S, but the price diff caught my attention. I read about same radio different power supply and still would have thought the switching might cost more. In your opinion...

Hey guys. Yesterday I installed a Yagi antenna and it all went great. I installed an inline amplifier and what a difference. I was able to pick up a UHF site I’ve been trying to get. The quality is 5x5. I do have a 10 port powered -/+ 0 dbi splitter. I want to avoid using a regular coax splitter...

Good afternoon all! Question: All thing being equal, and hypothetically of course; for general use CB (short range), longer distance communication (25+ miles) and 'skip', is a higher powered radio (export or mod) or a linear amplifier generally preferred? Or both? Again assuming the same mic...

Where would you place a pre amp on a 100 foot 50x2 BNC cable …. Closer to the scanner base or as close to the antenna as I can get? Thanks for your help

Hello I was wondering if anyone would have any suggestions for a nice antenna that could be inside of an office. I’m right beside the windows but this building was built in 1961 and it seems to block my signals pretty good. I tried a little Tram antenna inside the office but im coming over a bit...

Hello, I've just found the top of the rabbit hole that I was in for the last hour getting lost digging through this forum. There's allot of knowledge here and I was wondering if someone could help lead me through my signal issue I'm trying to solve. I have two signal amplifiers on...

Hi all, I am new to the scanner world. I was wondering if and in-line signal amplifier like one used for TV and FM would work on my Uniden BCD996P2 scanner with the stock antenna. One like this: https://www.amazon.com/gp/product/B001FY0B90/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I have been building an AM radio, and when powered on I was picking up what id presume to be radio waves (what I'd describe as a mishmash of "whooshing" sporadic oscillations). Alright all items for this project are the following: x1 MAX4026EWP+T op amp IC chip x2 1000 microfarad capacitors...

I am mounting a 120 cm 12 Vdc cooling fan to my RM ITALY KL 60 amp for 12Vdc mobile use. Both units will be supplied in parallel by a dash-mounted rocker switch. I want to make sure the fan doesn't induce a buzz into the xmit of the amp. Amp frequency range is 26-28 Mhz. How do I figure out what...

I have been trying to find and understand the correct information about this. I purchased a mini circuits amplifier thinking it was something else. I ended up with a Medium Power amplifier ZHL-1042. My interest was to purchase an LNA and ended up with a PA. My questions are the following: I...

Hello, I was wondering if I could have a little help with this CB Linear Amp I found recently. There is no make/model on it so I have not been finding anything on the internet about it. However, on the front it says "SS-600V". This leads me to believe it is home-made. The amp powers up and the...

I just got a cobra 29ltd and a wilson 1000 magnet mount antenna and have had for a few years a Texas star DX 667V. Now to get you guys up to speed, I mounted the radio under my dash of my chevy pickup. Ran the power of the radio to the fuse box and hooked into the a fuse and grounded it there on...

Hello everyone, First of all I know this is probably a really stupid idea but I'm just trying to consider all my potential options. I have a very long cable run from my Scantenna ST-2 to my 3 scanners that I run, total run of about 240'. I'm using tri-shielded RG6 direct burial from the tower...
