    Base Station Antenna Interaction

    I currently have a Maco V58 mounted on a heavy duty 32 foot mast. It works well where it is. I also have a new Maco M104C beam still in the box that I will be putting up in the next month or two. My plan A is to install a 40 foot tower, mount the M104C horizontally and the V58 above it with the...

    Powermax PM4-120 amp PSU issue

    More fun in the shack. I am working on connecting the CarlBuilt amp to the PM4-120 PSU. The recommendation from CarlBuilt is to run the amp at 14.5 volts so that is what I am attempting to do. I have the toggle set to fixed output, have a voltmeter connected to the PSU terminals and am using a...

    M104C Project

    I am replacing the Maco V58 on a 30 foot pole with a 40 foot tower with manual winch, Maco M104C mounted horizontally and the V58 above it without the groundplane radials. The antenna arrived yesterday. Now all that is left is: Snow to melt and ground to firm up. Get Digger's Hotline person to...

    President Lincoln II+ V4 board question

    Finally, a problem that's not of my doing. I loaned my Lincoln II+ V4 to a friend for a week for him to try out. When it came back to me, it would not even turn on. I think he may have had a high SWR issue or amp issue, but really could not be certain and ca't get a straight answer. All I had to...

    Amplifier power source

    I have a two month old Powermax PM4-120 amp PSU. I have a Carl Built 200HDC amp that can draw up to 46 or so amps. I also have several radios I use with it and each radio draws less than 15 amps. They are never used concurrently. Right now everything is connected to the PM4-120 via a...

    IRF520 compatibility question

    In my Anytone AT-5555N2 I see four IRF520s. One has N16K stamped on it, one has N17K and two have no markings. I have some other new ones from Vishay that are stamped N26K that I bought from Digi-key.com several months ago. Is there a reason Anytone would have three differently-stamped 520s or...

    Surgeon needed for RM Italy KL503HD

    Well it appears I may have inadvertently overdriven this amp with my toned-down Anytone AT-5555N II one too many times. AM still seems to work okay (from what little I use it on AM) but SSB is a bit of a crusty, busted-up, garbled mess even when driven by just a watt or two. Although I have a...

    How to diagnose and resolve an apparent RF issue in my Anytone AT-5555N II setup

    I am told that I have an RF issue in my setup that is causing clipping, distortion and generally a difficult to understand signal even when running low boost or even no boost. I vaguely know in general what it is but to be honest I do not know the proper/methodical way to problem solve this one...

    Looking for a little brother to my Anytone AT-5555N II

    I'm looking for a mobile for use in my truck. This mobile ideally has similar capabilities to the Anytone AT-5555N II but in a physically smaller package (lower power is fine). I looked at the President McKinley and while is certainly is small enough, at its price it is a bit underwhelming...

    Firmware update question from a returning hobbyist

    I recently purchased a new Anytone AT-5555N II. It is the first new radio I have purchased since a 2510 in about 1998, so before getting firmware updates from the internet was really a thing. I did check out the Anytone tech support site and they do say you can register to be alerted to...

    President Lincoln II + (V4) 10,11,12 meter mobile radio

    This President Lincoln II+ is version 4 (which is the latest version) and has AM/FM/CW/SSB. It is nearly new since I only purchased it about one month ago from ScottsRadios.com. I think many folks on here are familiar with him and his quality work. It has only been used several times on my bench...

    Maco Comet antenna retailer

    I am in the market for a Maco Comet 3+3 element beam. I don't see any site sponsors that sell the brand. I've hit up 3 or 4 of the usual vendors checking price (some price diffs), availability and shipping cost (large price diffs). Anyone have any suggestions for lesser-known but trustworthy...

    Tower model identification

    I am looking around for a good, used tower somewhere around 40 feet tall. I'm open to freestanding as well as ones that need to be guyed/bracketed. I plan on having a hinged base to help make it a bit easier to take it down because I do tend to like to try a lot of different things. To start...

    RM Italy KL300P Mobile Linear Amplifier

    I just purchased this from 88radio.com on 12/12/2022 but have changed my station plans and this amp no longer fits into them. It is in brand new condition. Asking $145 and includes CONUS priority mail shipping. It is also for sale locally.

    Which one would you choose?

    I have started collecting parts for the next stage of my station build. I am trying to find some stuff used if possible so I am starting looking now instead of waiting another 4 or 5 months. I expect some stuff I'll have to get new. My goal is to have a good DX setup plus a strong local setup...

    What is your typical noise level?

    When DX is not running, what is the general level of noise you get on your primary antenna? Mine is a Maco V58 up about 35 feet with a good SWR, no power lines or other antennae nearby, connected to a President Lincoln II V4 and my level never goes below about S5. Quite a bit of the time it is...

    KL503HD with Anytone AT-5555N II

    Is anyone here using an Anytone AT-5555N II together with an RM Italy KL503HD? If so, are you able to use the PWR knob on the radio to turn down the RF power on the radio so you're not overdriving the amp on either AM or SSB?

    How to guy a mast pole

    I am debating putting up three or four guy wires toward the top of a 30 foot tall mast that currently has a Maco V58 antenna on top. The bottom two sections of the mast are 11 gauge "1-7/8" x 11' Galvanized WT-40 Chain-Link Fence Line Posts. There is a 16 gauge, 6 foot long sleeve inside these...

    Clicking noise on new President Lincoln II+

    Just fired up my new Lincoln today after getting a new Maco V58 assembled, tuned and installed. The Maco V58 had SWR readings 6 feet off the ground of 1.3:1 on channel 1, 1.1:1 on channel 20 and 1.2:1 on channel 40. I messed with it for quite a while but this was the best I could do. Then I had...
