    Well, here is your first lesson. "73" is not plural. "73" is an old telegraph code that means "best regards", or something to that effect. It doesn't need to be pluralized. The same is true with the other numeric codes. Anyway, you have some good radios. I have several Kenwood 2M/70CM radios myself. I even have one for 220. It would be a benefit to contact a local amateur radio club. Often clubs have their own repeaters and can instruct you on how to program your radios and on the normal conventions for making contacts. I started out on 2 Meters (1967). It was a very different place then. Repeaters and FM were brand new. But I had a great time using my 5 Watt, AM, Heathkit Twoer. Those were fun times. I would also recommend that you go back and test for the General or Extra license. They are really not that hard and they will open up all of the HF bands to you. That will open up the rest of the world to you. If you go to, they have sample tests that you can take. Once you start scoring 90...

    Not quite true. An Amateur Radio license allows you to engage in two way communication with other radio amateurs and only on specific frequency bands. One way communication, like broadcasting music, is almost certainly not allowed. Go to and read the rules and regulations. I tried to read them myself, but the regulations are not in my language. Those are international short wave frequencies. Most of the radio stations in those bands are licensed, by their originating country, to broadcast. And they are under very strict regulations. To get good coverage many of those stations run more than 10-20 Kilowatts. Some use up to 100 Kilowatts. I'm pretty sure that is more than you are allowed to use and probably more than you can set up.

    Good day, everyone. I am brand new to all of this having received my Tech ticket back in November. Honestly, I have absolutely no idea what I'm doing and have yet to even key up a radio. I'm currently working on setting up a mobile rig as that will be my primary rig. I don't think the apartment management would appreciate antennas going up around my building. The rig will have 1 mobile (Kenwood TM281) and 2 HTs (Yaesu FT65 and AnyTone DV878 UV) that I can easily take inside and use if needed. I have replaced the rubber ducks with Diamond SRJ77CAs which has helped with receiving at least. One major issue I have is programming the radios. I have absolutely no idea what I'm doing there so hopefully I can get with one of the guys from the local club soon to help me with that. I'm also still working on mounting options as I just don't have a lot of room to work with in my truck but hopefully I'll get that sorted out soon also. I look forward to finally getting things set up and operational so I can actually start...

    Those resistors "on top of the tubes" are not just resistors. They are "parasitic suppressors", meaning that they each have a length of bare wire, probably 20 or 18 gauge, wrapped in a coil AROUND the body of the resistor and soldered at both ends. Without that little bit of inductance in place (like with just a bare resistor), the finals will oscillate all by themselves and probably become no good in less time than it takes to say it. The manual shows the resistors as (I believe) 22 ohms @ 2 watts. You can go larger on the power side but don't change the resistance.

    It appears to me that the TS480HX Power Amp may be going into Protect Mode. I recall two times of extended use ( during long contest operation , hours , hours and Higher SWR Tuning scenarios ), I have seen the TS480HX base unit get warm, resulting in higher Fan speed. Then the Base Unit shuts the Radio down , with a Power Down : Power Reset on its own. This was during Summer month’s higher room temps / high humidity. If it is a used Radio - may suspect the Finals or Power Amplifier protect circuit.

    Hello, I am new here and looking forward to learning this new Amateur Radio hobby I am in. I just passed my Technician & General tests at the Cowtown HAMFest in Ft Worth in January. I am now learning about different modes of operation as I consider what 2m/70cm rig(s) to get. I have a Elmer/Mentor that is going to loan me a HF rig. I hope to become familiar with what I want to do with HF using his rig. My primary interest at this point is to make my own antennas. I am going to make my own 2m/70cm ground plane antenna for a mobile/HT type radio and put up an inverted V dipole for HF. I am a retired network engineer, but have never worked on the radio and antenna end, so this is a new angle for me that I enjoy. I look forward to learning and meeting new people with common interests in this hobby. Thanks, Brent Johnson KI5HXM

    The FT-60 looks like a descent hand held. I have several 2M/440MHz "under the dash" type of radios (Kenwood TM-201B and a TM-V7). The "under the dash" type of radio generally costs considerably more than a hand held. The TM-V7 went for over $700 new. Whereas, the FT-60 only goes for about $150. And now, the hand held radios are offering the same utilities as the "under the dash" type. But, I don't know what you mean by "Or a handheld that I can route through my car to increase the signal level." You can probably get a better signal by using a external antenna, rather then the rubber ducky on the hand held. I have 3-Element Yagi for 2 Meters, that I bought over 50 years ago, that works great in my area. I also have a Diamond X30A Dual Band (2M/70CM) Base/Repeater antenna. If you put that X30A on a 20-30 foot mast, you will hit every repeater within a 50-100 mile radius.

    I'm about to be getting my license for Ham Radio. I've been looking at radios and I'm not sure whats good vs bad. I wanna do something I can easily put in my car. Or a handheld that I can route through my car to increase the signal level. I was hoping for like under $200 or maybe just a little over. Any help I could get would be great. I'm still learning and getting into Ham Radio.

    Yes, you should both be licensed (with a callsign) to talk on the amateur bands. Getting a license is easy nowadays, find a local radio club and they will help you...

    Hey everyone. New to the ham radio world. My brother gave me a Yaesu ft 25 r as a gift that we could use to communicate while hunting. After doing some research, it looks like we need a license to talk to each other. Is that correct? Sorry if it’s been asked a million times. Thanks for your help.

    Never heard of anyone, ever, ID'ing a crossband radio. When you ID you are ID'ing both radios at the same time. I feel like KW has the feature for using the 71a as a stand alone crossband repeater, not for your application as a single user.

    Here's a question for the circuit board designers. My wife loves our cheap chinese touch sensitive bedside lights. So do I, but the slightest whif of RF switches them on and off. So a CW contact has our bedroom window flashing like the bridge of a warship! I'm told that it's because the cheap chinese circuit boards have no filters. So, is there a designer out there who can design an easily built, small, circuit board that won't be so hellishly sensitive to rf but will still do the job of providing touch sensitivity to our lamps? I'm happy to experiment and build something, provided it won't blow us up!! Richard G4JJP
