    Hello all, Fairly new to the hobby, and enjoying the radio almost every day! I monitor in my work truck throughout my shift, and rather than burn though batteries and worry about constant charging, I use the Yaesu mobile power adapter. It powers the radio via the cigarette lighter and bypasses the battery alltogether. As a result, I hardly discharge my batteries at all, and they end up just sitting around with a charge for long periods of time. Im curious if leaving an NiMh battery alone for a long time reduces the amount of life I can expect out of it. I have the 1400 mAh battery, and a 2100 mAh battery as a backup in my work bag. I'm considering running down each battery about once a month or so (so it can get a fresh charge), but I'm not sure if there is any benifit to it. I'm sure there are different opinions regarding battery care and extracting the maximum amount of cycles from them. Curious if anyone can chime in with their thoughts. Thnaks!

    Just over a year ago I bought a new Icom ID51E+, I had been on DMR for just over a year prior to that. Whereas I can use my TYT MD-380 for over an hour whilst going for a walk (working through a local repeater) I can't do the same with the Icom, in fact I really struggle with a QSO over five minutes, why? well because the ID51E+ gets so hot! I noticed this straight away and phoned the vendor who supplied it, they were really dismissive about it and said what did I expect, the PA is causing the heat and it is only a small radio! To be honest, If I had knew I would have just waited a little while and bought a D-star mobile use as a home base.

    No, not if it's done properly, however, you need a transmitter with enough bandwidth to carry the information. An amateur transceiver is limited to a few kHz, whereas you need a few hundred. Forget this idea, use the internet instead...

    Not quite sure what you are describing here, but it is possible to use an audio amplifier for low frequencies, but you won't get the full output power. Yes, using a beam or Yagi antenna. You will lose your license if you transmit music.

    What is the actual radio station? Have you check to see if they have an internet page and live stream their broadcasts? For example, a list if Turkish radio stations can be found (click) here I picked one station, did a web-search and found it's page İstanbul FM I don't understand any Turkish, but I will hazard a guess that the box to the lower left of the screen is to live.

    In order to program the AT-D878, go here: https://www.bridgecomsystems.com/pages/download-a-codeplug and pick up the Mississippi state code plug and look up programming on the unit here: http://papasys.com/attachments/DMR_CodePlug-101_AnyTone_20190203.pdf I have the AT-D878UV-bt and it is a really nice unit. You can also get the Contact Manager to get the CSV file of all of the DMR contacts -- then you know who you are talking to on DMR.

    Thanks for the info. I've seen the 73 done both ways even tho it isn't necessary to have it plural. I'm in the local club and they've been very helpful and encouraging. I've gotten codeplugs for the 878 from a couple of them. I just have to figure out how to set it up. I've had no such luck with the FT65 because no one else locally has one. I have a few things manually in but haven't had a chance to check it out yet. As for the Kenwood, Hopefully someone will have something useful to help me set it up once i can get it installed. I would eventually like to get my general but I'm not ready for that yet. I'm still trying to get things set up so I can even put the tech to use which i hope to do soon before tornado season kicks off in the Deep South in full affect. I've found some general classes on YouTube that I have saved for future use. As for Morse Code, I have no interest in fooling with that. I'm confused enough as it is. That's what kept me from doing this in the 80s so I opted for CB at that...

    My electric heater consumes 1.5 kilowatts. My transmitter can consume also. And auto amplifier can climb to this number. Is it too difficult to connect sdr transmitter to automobile woofer amp and than connect to antenna ? Does it work ? And is it possible to direct the antennas output only to west ? I will play music at the background and speak on it.

    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 QRZ.com, 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 http://trac.org.tr/amator-telsizcilik/nasil-olunur 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...

    K7KBN replied to a thread YEASU 2100B OUTPUT in Accessories
    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.
