    You're overloading the front end of the TECSUN radio?

    Thank you, I was losing hope and interest in the hobby. You can only learn so much before you start having questions that can only be answered by talking to someone.

    How close is the receiver antenna to the transmitter antenna? Sounds like you're trying to hear yourself 100w strong on a receiver that is right next to the transmitter. That would be very very mean to the receiver. Even as little as 12w on the Sirio827 overloads the receiver i have listening on my other antenna.

    My guess is trying to run a radio at 100 watts output, off a 12v battery IS the problem. Icoms love full voltage and current available and running at less is asking for trouble. Try turning down the power output and test again. It should clean up unless the available voltage is too low. Then maybe some charging is in order.

    Hello! I'm thinking about buying a new antenna for use on the two meter band, and I have narrowed it down to these two antennas: Diamond F22A Tram 1480 I am planning to raise the antenna to at least 25 feet of the ground. It will also be used with a Kennwood TM-281 and be fed with 40 or so feet of RG-213 coax or better. The antenna only need to work on the two meter band, I'm not really interested in 70cm.

    Page 12 of the manual shows pins 1 & 7 are used for the microphone circuit. For example:- An old pair of headphones you can chop up would be easy to connect to a P.C. Cut the wire near the speaker end of the headphones. Strip both the inner and outer conductors from one of the speaker wires, leaving the other one unused. Insert a wire into either side of the the notch, (closest to the notch) on the Icom microphone. Plug into microphone input on computer, hit software record and sing away (you might have to hold the PTT button). If it doesn't work, swap the wires around or use the other speaker wire.

    I already played with the mic gain and ALC, but got no improvement. I suspect the mic so I would like to make an adapter to test to mic with a PC. Where can I find a an example of doing it ?

    Well, a typical car battery will comfortably run it on full power for about half an hour, longer if the SWR is low. Is it possible to make an adaptor for the microphone and plug it into a PC or HiFi to hear the audio quality before it goes into the radio? Could be there's just too much mic gain, check the ALC on the radio is not going crazy when you transmit (it shouldn't move much).

    I own a ICOM IC-178 transceiver powered with a 12V battery. It drives a Hustler 6BTV antenna located at 100 feets from the house. The station is at 15 feets from the ground in a second floor room. The SWR from the station has been tested and less that 1.5. Using the ICOM mic that comes with the transceiver, and listening with a TECSUN radio in SSB mode, the transmitted sound is very distorded at any MIC gain and RF power. What could be the cause ?

    Hi, I know nothing about Software Defined Radio, FPGA, integrated circuits, electronics, et cetera. I do know that they are fields my father is interested in. A little background, he's worked with NASA and the European Space Agency for the majority of his career as a software architect (as in the guy that is responsible for designing the software for satellites) and he loves to do electronics in his spare time. He's recently retired, but used to run seminars for ESA's electronics club and he did few workshops on FPGA and Software Defined Radio for them. Two years ago I contacted digikey in the States and got super lucky with a knowledgable salesperson and I bought him his first integrated FPGA board. Last year I called them up again and they were literally amazing (I can't recommend them enough) and I bought him the MAX 10 FPGA 10M50 EVAL KIT, which blew his mind that I had actually bought something he wanted - an impossible task. I called Digikey today and they were a little at a loss to recommend any...

    I'm pretty new to ham radio, so please excuse my naivety. I have an icom 2720 in my car, and I have a baofeng UV-82wp. I decided to try and get a little creative and test out crossband repeat. I'm not sure if I chose a good test frequency to try out though.... I wanted to test it in my own before trying to reach out to anyone else. The only other radio I have working at the moment is a pair of Motorola FRS walkie talkies. My plan was to try and set up the baofeng to transmit through the 2720, and pick it up on the Motorola. My first step was to set all three radios to the same FRS frequency, and set the 2720 and Baofeng to frequency mode, and see if I could get each radio to transmit to each other simplex.

    SHEEPDOGGIT started a thread Portable Radios Yaesu FT-891 & FTM-400XDR vs. Yaesu FT-991A in Yaesu
    I'm new to ham radio and am in the process of studying to take my Technician & General exams simultaneously over in the next few months. Can anyone familiar with the Yaesu FT-891, Yaesu FTM-400XDR (or perhaps the FTM-100DR) AND Yaesu FT-991A shed some light on the pro's and con's of owning either the first two as a pair versus the latter as a stand alone? I'm primarily looking for a portable solution (and not necessarily a true mobile or base station only rig). If it helps, my priority is to have an HF, VHF/UHF, & C4FM FDMA solution that is first and foremost portable since I am HOA-limited (followed by the desire for an adequate base station, then possibly a mobile option down the road). In other words, while a true mobile rig would be nice, it's not as important as being portable and serving as a base station at home (though DXing will be limited by HOA restraints). Are there any performance issues regarding the filters of the FT-891 vs the FT991A, for example? Are there benefits to having...

    I did the same thing when I was first licensed. I knew joining a club was the best way to learn. I tried a couple of different clubs. The first one I went to completely ignored me at my first meeting. I never went back (except once and in a different capacity.) The second club I tried acknowledged me and made me feel welcome. (In retrospect, it may have been because they saw a sucker coming.) Now, almost nine years later, I have served as Vice President and now President (starting my eighth year.) I must be doing a good job because the club voted me Ham Of The Year for 2019. Being a member of the club helped me gain confidence in amateur radio and I'm now a member of the local ARES group, Public Information Coordinator for the Section, and a Fire Department volunteer in the city where my club is located. I also became a Team Leader with our local VEC and administer the bulk of licensing examinations given in our county. As the OP has said, don't go with your first choice if other clubs are...

    Just wanted to give my experience joining a Ham Radio Club; as a total newbie to the hobby. I received my call sign in Feb 2019. I immediately started looking for a local club in Morris County. As Ive read, joining a local club is how you learn more about the hobby. I found a local club from the ARRL website. I joined this local radio club and found out it was total bootleg; what a waste of money! They were unorganized and only had interest in catering to those knowledgeable members. I got the impression they had no interest in teaching new members. Their website is a couple years out of date and provided no useful information for a new person to the hobby. I made it clear I was a total newbie with no knowledge of the hobby but it didnít seem to matter. I thought clubs would have some type of new member orientation but with this club you are basically left to flounder on your own. I attended 3 meetings and not once was there an acknowledgment about new members; other than their initial voting in. My point...

    Yep, RF is getting into that system. There could be other ways to fix the problem but if you can get the antenna further away from that box that would be good.

    Hi, Just moved in to a new house with a fitted burglar alarm. When I key-up on HF, the alarm goes off. I'd prefer not to permanently disable the alarm as it's quite useful for deterring burglars! I can't find any fuse or isolator switch for it. Can anyone offer any advice?

    You are on the right track. I haven't used a Nano yet but they are on my radar. Testing and tuning with a decent instrument will teach you more about antenna theory and what works versus what does not more than any book. I'm lucky that my job has anything I could want to test antennae. As Hams, we are trusted by the FCC to design our equipment to operate within specified parameters and our reward is an efficient piece of gear that works as it should. I commend you for wanting to do just that,
