    Installed a 144/220/440 antenna today. surprisingly it performs better
    mounted on the hatch instead of the roof. The exact opposite of the 144/440
    I have currently mounted on the roof.

    $20.71 Homebrew 6M dipole

    Posted: 07 Jul 2022 06:33 PM PDT https://www.reddit.com/r/amateurradio/comments/vtyqdq/2071_homebrew_6m_dipole/


    After 22 years off the air Im back with an IC-7300. This is the first radio
    Ive had that has 6M so Ive been playing FT8 on it. I had a repurposed 2M
    J-pole that I was using the long element as a vertical radiator. It worked
    but I really wanted something a bit better. I dug around in my junk box
    plus made a trip to the local big box hardware stores looking for stuff I
    could use to make a rotatable dipole. The pictures show what I put together
    for an outlay of $20.71. Ill be adding to that cost when I buy some 1"
    schedule 80 PVC to get it up in the air but Ill not include that in the
    cost of the dipole. It will alternately hold up the 10M dipole Im cooking
    up so I guess I could spread the cost across all my antenna experiments. Disclaimer: I know I should have done something to waterproof the feed
    point. Remember this is an amateur radio project not something mission
    critical or headed to commercial sales. Besides in North Central Washington state we dont see much rain.
    Here is the overall view of the antenna. The wheelie bin would have been
    its final resting place had it not worked out. https://preview.redd.it/2vdvg3twv8a91.jpg?width=2817&format=pjpg&auto=webp&s=c2d3e763149c3c14011d91ce8648448bd3b6f866
    Here is a close-up of the center connector. Tie wraps hold the NMO mount to
    the tee. https://preview.redd.it/d3zmnwe2w8a91.jpg?width=3001&format=pjpg&auto=webp&s=475aaeac1a9bc487d2b096d663c3ce29f169ca76
    Here is a view of the inside of the center. I used a nylon spacer to join
    the 2 marker rods together. I had to drill it out a bit to make them fit.
    In order to make sure the pieces stayed in place I pour some casting resin
    into the tee. I taped off where the 1" schedule 80 will go to get it up in
    the air so no resin would stick there. https://preview.redd.it/j5tuh2wkw8a91.jpg?width=3023&format=pjpg&auto=webp&s=57bd9815b4fa12f542d0432e599f77618d1f5f23

    Where should I point my antenna to receive cosmic noise and not receive
    other signals?

    Posted: 07 Jul 2022 02:44 PM PDT https://www.reddit.com/r/amateurradio/comments/vtty49/where_should_i_point_my_antenna_to_receive_cosmic/


    TLDR:
    -I have a yagi antenna parallel to ground. I need it to not receive the
    noise from ground and man made sources, and to receive the noise from sky.
    How do I make sure of that? Which way should I point the antenna in the sky
    to maximize my chances of success?
    -Read below for more info-
    I’m hoping to experiment with radio astronomy this winter. I did it at
    40MHz last winter but the terrestrial noise levels were too high, so I couldn’t get the thing to work. This winter I will bump up the frequency to 160MHz.
    I know 160MHz isn’t ideal, but I’m building my own equipment, and the best measuring equipment that I currently have is a 300MHz scope (DS2072A hacked
    to 300MHz) so even 160MHz is pushing it. The ideal frequency is of course 1420MHz or 21cm hydrogen line, but I don’t have the skill or the equipment
    to build anything capable of making observations at that frequency.
    The plan currently is having 2x5 element yagis horizontally separated 1.5 wavelengths apart, 0.5 wavelengths above the ground, parallel to it.
    The LNA will be a BF995 dual gate MOSFET noise matched for best noise
    figure, no other preselector unless I need it, in which case I will
    probably have to switch to gain matching for the bandpass filters. I’m “hoping” to achieve something like less than 2dB noise figure.
    The antenna setup gives me the best gain at about 25 degrees above ground
    and about 36 degrees half power beamwidth. I know that’s not enough to actually resolve anything, but for now all I want to do is to confirm that
    I can actually receive something from the sky, which is something I failed
    to do last winter at 40MHz. I used MMANA-GAL for simulations.
    The plan is to get the signal recorded on a PC with a soundcard. Hopefully,
    the signal strength will vary over time with a period of 23 hours and 56 minutes, a sidereal day. After that I will think about moving to a higher frequency and/or building a larger antenna array to decrease the beamwidth. I’m not sure if the antenna is going to receive any noise due to blackbody radiation from the ground. I guess I just don’t know which way I should “point” the antenna and how to prevent the antenna from receiving the noise sources that it shouldn’t receive, like blackbody radiation from earth and man made signals. I feel like having the antenna parallel to ground is
    going to make it receive man made noise and the noise from the ground. submitted by /u/nitratehoarder

    Powerpole question - do they normally come with contacts?

    I asked Mouser as well, but they usually take a while to respond:
    Mouser Link
    Do those come with contacts? I noticed some parts on there say "housing
    only" - its not super clear.
    I want to use them for a mobile install using 10 awg wire.

    I have recently bought a cb radio and am working towards my technicians
    license and came across my local towns emergency plan for natural disasters
    and worse... it appears that my what was local amateur radio club played a
    big role in establishing communications after a disaster. Only thing is; is that to mine and others knowledge this club has been disbanded and is no
    longer operating... do I contact the city about this? I dont feel as though
    I would have much say as I was never part of this club and the head of the
    club has since passed. I wish I could start it back up but I have no clue
    where to even start with that. submitted by /u/Kmcgr0435

    Using same antenna and tuner with different radio

    Posted: 07 Jul 2022 05:33 PM PDT https://www.reddit.com/r/amateurradio/comments/vtxiyu/using_same_antenna_and_tuner_with_different_radio/


    I have a QRP Labs QCX but dont have a resonant antenna to use with it at
    the moment. I also still need to get an antenna analyzer and some other
    things so I cant build an antenna immediately. I do have access to another radio with tuner (LDG Z100) and a long wire antenna. Can I use my other
    radio and the Z100 to find a match at the frequency I will be operating at
    and then just swap the QCX with the other radio? submitted by

    Im sure this has been asked before, but I cant find anything on the topic.
    A lot of theories on why that is, but maybe it doesnt matter. :)
    Can I use this old Yaesu tuner I acquired (FC-30) with another radio? I
    managed to find a pin out for the cable, I think, and I can keep digging
    and start testing, just wondering if there is something Im missing - maybe something proprietary involved. Also, if anyone else has done this or has
    found documentation around doing it, I would love to not reinvent the
    wheel. I know Im not the first person to think about this, just having a
    hard time and could use some advice!
    Thanks in advance. submitted by /u/tonytocar

    Can't seem to use microphone on laptop since I connected FT-991A via USB.

    Posted: 07 Jul 2022 06:29 PM PDT https://www.reddit.com/r/amateurradio/comments/vtynki/cant_seem_to_use_microphone_on_laptop_since_i/


    Howdy yall,
    A few weeks ago, I configured my FT-991A and Windows 11 laptop to work
    together using wsjtx software for FT8 and other digital modes. That works great. But I think wsjtx and my radio connection is interfering with my
    ability to use a microphone with my laptop.
    This afternoon, I tried for the first time in a long time to use a
    microphone through my laptop and it doesnt work. In Windows settings,
    trying to run a mic test, the only audio I get through my "microphone" is
    audio from the FT-991A, which is whatever is coming over the frequency to
    which it is tuned.
    I tried the laptops built-in mic, a set of earbuds with a tiny mic in the
    cord, and a set of gaming headphones with a boom mic, along with every
    setting I could find, and nothing worked. The only mic audio comes from the radio, nothing is heard when I speak through any mic. Audio output through
    the buds and headphones is just fine when Im on YouTube, other websites
    with sound, etc., but its like theres not even a microphone in the room
    when I speak.
    Unplugging the USB cable from the radio to the laptop didnt work either.
    When I do that, mic audio is just dead, i.e., no sound from the radio or
    any of the mics.
    Im planning to use the Long Island CW Club in the near future to learn CW.
    They use a Zoom connection and prefer a working mic, so Im trying to get
    one up and running.
    Any help and expertise is much appreciated. Is there some setting or
    checkbox that Im overlooking? Thanks for your time. submitted by
