    Thank you for the PSA on the overhand-underhand cable wrap at 15:25. More hams need to know this. It applies to all cordage.

    not sure why its takes an hour long video to say use waveguide's for everything. maybe LMR-600 if you're poor.

      Amen! Thanks for the info. Got everything I needed by 11 seconds.

      And you forgot the nitrogen cylinders to fill the guides! Shame!😊

    Informative video thanks. Josh, side topic questions for you regarding your KG-Q10H. A few quirks with mine that BuyTwoWayRadio say is normal. Curious if you have the same issues.
    1. The selection ring knob under the volume knob has play in it up and down.
    2. When you turn the selection knob clockwise when you’re on the first menu (short press), it does through the menu in the normal ascending order. When you’re on the second menu (long press), clockwise now takes you through the menus backwards.
    3. I keep the display on the channel name that I gave the channel. Sometimes during our Net, instead of the channel name, it will display a 6 digit number when someone is talking. It then revert back to the channel name at the end of their transmission.
    4. On menu item #20, the second line number flickers on the display. This happens on menu #23 also.
    Thanks I appreciate it.

    I tell people coax is a tradeoff... loss, flexibility, weight, and budget! Starting out a new ham may not have the budget for a super low loss feedline, as a station matures and things get upgraded coax is a good place to start!
    Connectors can get hot too! A friend brought his 1.5kw amp over for an EME contest, fed 7/8 heliax(LDF5-50) with a short jumper of 1/2 inch super flex heliax(FSJ4-50b). N connectors... halfway through the night in the middle of a sequence BANG, blew a connector apart! Connector may have had a defect, or he installed it wrong(doubtful, he knew what he is doing but always possible to make a mistake). Other connector on the end of the 3' jumper was so hot we couldn't touch it. This was pre wsjt days so CW 2 1/2 minute transmit, 2 1/2 minute receive sequences so lots of time to develop heat. Specs on FSJ4-50 state 1.45kw avg power... so ragged edge on ratings...

    @25:56 that is one of the 7 questions I missed. Some things were just to hard and I knew I could miss some questions and still pass. W2UWK!

    Not sure if anyone addressed this, but I believe the center conductor of 50 Ohm coax should measure (ideally) zero Ohms at DC, not 50 Ohms. 😊(1:00:06 into video)

    The type of coax you should is largely dependent on the distance from the radio to the antenna but my recomendation as a radio tech and ham is use what you can afford... Ive tested brands and for the most part comparing same size and brand just get what you can easily afford. for instance purchasing something like Storm cabel which is off the charts expensive and chpaper brands there is almost no difference in the actual loss and performance. Don't let brand name make you go broke especially on HF. I really like watching this guys stuff but the equiment he is able to get is really too expensive for the need. Unless you are going to build a tower, save your money and remember that the whole point to HF is using the least ammount of power for the most difference... I bagged Antartica on 50mhz with 5 watts and on the same day hit Roratonga... thats the real stuff that bragging rights are made of. And by no means am I throwing shade on Ham Radio Crash course... Keep it simple Keep it real and Keep it fun. All the best

    Damn! I was planning on using RG-Josh for my next coax run :/

    I wonder if it would be hard to install a VHF mobile transceiver and HF mobile transceiver in a boat. Since I love boating and amateur radio, 73 Kq4hcu.

    A multimeter won’t measure 50 ohm coax as 50 ohms. It will measure its dc resistance not its rf impedance.

    10:10... eh, if you can afford the radio it's going into, you can afford decent coax.

    If you think LMR-400 is pricey, try LMR -600 and LDF 5-50A.

    • @MaryBrownForFreedom

      FSJ4-50b is a good sub for LMR-400, slightly less loss and can often be found for $1ish a foot on ebay. Slightly larger in diameter, stiffer to an extent(still good for rotor loops if you make them long). For home station use, no way would i drag it portable for HF, for a VHF rover? Yes...

    Why doesnt anyone talk about 90 degree adaptors?

    • @CoaxAndCampstools
      @CoaxAndCampstools 4 місяці тому +5

      Because most prefer their coax to be colder than that.

      Whole ball of worms! Some 90's are fine, some are absolute trash! Testing a bunch from random sources could be an eye opener.. same for testing the super cheap connectors vs say an Amphenol RF or DXE connex connector

    Rule #1, avoid copper clad aluminum.
