    Hi all. Some months ago I purchased a Czech military radio and up until now I haven't had much time to do anything with it, however I recently got it unpacked and struck it up as there was some charge left in the NiCad battery and had a little play around with it. These particular field radio's don't come with any sort of charger for the battery, not quite sure why, perhaps they are meant to be plugged into a vehicle, as out in the field there will be no power facilities. To charge these cells up I'm going to have to connect a voltage direct to the battery pack pins but I'm unsure what voltage to be supplying to the pack and this goes for any sort of re-chargeable battery not just my mil radio. With most 12 volt lead acid batteries, the charge voltage is about 2 volts over and above the running voltage and I wondered what I should feed into any sort of NiCad cell, regardless of it's running voltage. For example: If a 12v LA battery is 14v charge, does a 7.2v NiCad need 8-9v or a 9.6v pack need...

    I'm a 65 year old grandfather who would like to be prepared in the event some parts of the communications grid fails due to natural disaster or other causes. I live near Houston, TX and have kids in Dallas, TX. I want to put something in both of our houses in preparation for a disaster so we can communicate. Money is not a big issue here, just want something that will work. Thanks.

    Good morning all. I recently received my technician license and want to listen in to learn the radio etiquette. I purchased the Yaesu ft60r and the programming software to put repeaters into my transceiver. In the software it has a category to insert the following: tone,dcs,ccts,none and so forth. I put my repeat channels on tone thinking that I would be able to listen but I'm not hearing anything on any of the repeater channels. Can someone tell me what I'm doing wrong?

    Hi, I'm Charlie, K3UIM, 86 years old and waiting for God to call me home. I love ham radio, WordPerfect as a word processor and BMW motorcycles. (Stopped riding at 75. Ö sigh ...) I retired from tool making at Talon, Inc. in Meadville, Pa after 33 1/2 years, to the day. I enjoy tinkering with electronics, modifying circuitry and home-brewing. After about 25 years of hamming I dropped out for about 25 years and just recently found myself hankering for the smell of melted rosin. (Hi) I maintained my license, figuring I'd one day retire and get back into the rat race. I work 40 CW and find it a wee bit difficult getting back up to the 20 wpm speed I used to do. (Funny thing about that, I've discovered a lot of things I "used to be able to do" since aging. sigh.) Enjoy life! Charlie

    Hi, I'm just moving from UHF/VHF. I've got an IC-7300 connected to a simple CX50 dipole (on the roof) and a USB cable to a computer. That's about as far as I've got. I can find CW signals on the 7300, but I'd be grateful for any recommendations for what software to run on the computer to talk to the IC-7300 and generate/decode the morse. Eventually, I'd like to use a paddle, but to experience the communication I thought it'd be better run it through a program. Eventually, I'd like to do a lot more on HF, but CW is calling me now. I've no idea if the antenna is set up correctly, but that's a question for another day. Thanks in advance for any info, KR0Y

    I'm brand new to amateur radio, and just purchased a FT3DR. I live in an HOA and haven't figured out the antenna issue yet, but got a magnetized roof antenna for the car. I bought a Diamond SRH77CA antenna for the HT for walking around. I was sitting at home and wanted to see if I could reach anyone on 146.520 I noticed that the screen displays DTMF when I transmit. Why? Is there a set up problem that is causing this, and is this the reason I'm not getting any replies? Also, when i key up a local transmitter I get a reply in CW. Is this related to the same DTMF issue? thanks in advance joe AD2AI

    Hello, I am building a yagi with center frequency of 859 MHz for cell phone. It has 19 elements and is 80" long. It uses a conductive beam with the elements bonded. I have used VK5DJ yagi calculator for dimensions. I would like to support it near the center of the beam. I have made a non-metallic stub for it to mount to (pvc) which will be bolted to the mast with 2 quarter-20 bolts. I am wondering if using steel bolts to connect the stub to the beam will have an adverse affect on performance, as they will be in the path of the signal beam. Thanks...

    Hello all, new to HAM, studying for my general. I have no permanent base station at home currently, I just have a Baofeng 8 watt (forgot the model), FT3DR, and 400XDR in my jeep, so currently no HF capacity. I'd like to have a unit that is portable for HF so I'm eyeballing the FT818 with some accessories but it's low power. How feasible is it to use an HF amplifier on the 818 to get to say 50 watts, and then just grab the FT818 and a couple accessories for mobile base station operation? I don't know anything about amplifiers and I'm not convinced the 818 is the best way to go. Been looking on ebay and not coming up with much. KI5HPC

    Hi, I am a bit of a 'newbee' but noting in my training has told me how to estimate the power needed to get a signal a distance. I am not talking line of sight for which there are no doubt caculators. I want to get a reasionable signal to a friend in Finland about 2000km from me just outside london. Clearly this will rely on reflectiion and signal bounce (and of course atmospheric conditions etc), but how do I know whether to use 10wats 100 or 1000 (which I cannot because of my licence anyway). Is there a rule of thumb for this and where can I find it? best

I was able to receive crystal clear, but could not transmit. Iíve tried doing some research online, but conking youíre short on an answer. Anyone have an idea on what the issue might be? Iím suspecting I might need to program the radio somehow, but not sure. Again, total newbie here if you canít tell. Thanks in advance for your help. -Mike

    I am new to ham radio. I've purchased a Tecson S2000 receiver and would like to connect an improved external PLUG-IN indoor. Would like to improve all bands but especially extreme distance reception. Would like to use one that does not overwhelm the RF input, good signal to noise ratio. The antenna would be located near the unit. I believe the receiver has a coax input for this feature. However, I would need to know if the antenna coax needs to be grounded one end, both ends and information of that sort. Any help with these matters would be greatly appreciated. I've browsed around somewhat but have found no significant information that addresses specific brands and models of antennas for this application. If a small outdoor antenna is applicable I can mount such a device as well if the performance over an indoor would justify such a product.

    Hi all from South Africa I have a Kenwood R-820 Receiver that has developed a problem which I would appreciate some input on. I bought it some years ago for very little and have used it from time to time without issues. The rig works, and once it's been on for a while and settled down it receives beautifully though it does look like it has had some mods done to it by previous owners. The digital readout can be temperamental at times and I have sorted it out once before and will do so again. I live with it for now. However, if I feed a Kenwood SP-230 speaker from the speaker output at the back and turn up the AF output a little beyond a certain (fairly low level) point, the audio output suddenly becomes a somewhat squawky almost Klaxon-sounding tone (it sounds a bit like a drunken first-year university student barfing into the grass alongside the road somewhere), the digital frequency readout goes funny, the S-meter dips as the backlight dims, and then everything returns to normal if the AF output...
