10meter radio transcievers Alinco DR-135UK 25.000-29.90 MHz (programmable) - needs ALINCO ERW-10.Ham radio? 0-25 Watt USB/LSB (variable) not transmitting it blows fuse. right>? bad caps inside shorted too cause or bad DC power regulator ) assumes using right sized fuse. answers. it does need service, if blows only TX mode, antenna good. the fuse needs more amps to TX 25times more 12amp min, 15amp fuse or 20. one model said 15amp fuse. DR135, books on UK version not easy to find ask maker , they have vast manuals I see http://www.alinco.com/pdffiles/

This is a front end issue that has to be remedied by a radio tech or the factory. The front end is the receiver and it takes special tools and equipment to test and calibrate it correctly,, The only thing you can do is check the ICOM page to see where it can be serviced.

First, check all your antenna leads and connections.. that's where to start first.

I don't have much experience of radio transceivers but I do have a couple of ideas. The big question is how do you know your radio transmits 30 miles but receives only 6 miles? Clearly you have a friend with a transceiver and you have been playing around together until you formed those conclusions. What if the other radio received well but didn't transmit so well? Have both radios been checked with a field strength meter to ensure they are both radiating similar power outputs? Do you receive the carrier wave but no audio at a range greater than 6 miles? If so your friend's radio (and others) might have a modulation problem. Has the signal(s) been analysed with an oscilloscope? It is often imagined the transmission envelope is circular radiating from the antenna at the centre but that is often wrong. The radiation envelope is often distorted by a ground plane. Imagine an antenna mounted at the centre of an aluminium boat hull, the radiation envelope would be elliptical in line with the hull. Even with a fibreglass hull the presence of metal masses can pull the radiation envelope out of shape lengthening the range of both transmission and receiving in one direction and shortening them in another. There is another possibility to poor reception and that is a high amount of interference that might be airborne being received by the internal radio circuitry, by several means - antenna or the poor screening of the downlead and could be aggravated by poor grounding. Interference can also be on the supply line and both types can be generated by a host of electrical or electronic equipment. Generators and motors, voltage regulators or stabilisers, local oscillators, fluorescent lighting, inverters, computers... The basic radio of the old days could have the Squelch turned off and an experienced operator can hear much of what is or isn't happening.

sounds more like a thermal issue than a battery.

I really, really suspect your programming.

In the USA, repair and service of a radio frequency transmitter requires a 1st, 2nd, or 3rd class FCC license. The other bad news is the radio probably uses a solid-state chip for tuning, so special tools will be needed to remove and install a new chip. This is best left to a factory repair center.

did you check the manufactures web site ebay is your friend

It may have been PLL instead of PPL. If so, that stands for Phase-Locked Loop, and is the circuit that the transmitter needs to generate the desired frequency to transmit on. That being the case, there's no user remedy and the unit must be serviced by a qualified radio shop.

I thought it was the speaker

This is a HF, VHF and UHF transceiver. All of the specification are at: http://www.icomamerica.com/en/products/amateur/hf/7100/specifications.aspx

any ham radio store can fix them. or can send to the factory. and the good thing about amateur radio is individuals cant charge you to fix it.. LOL. just for price of parts.

Charging a battery requires two components. A working charger and a functioning battery. The concept is simple. A battery charger must output more voltage than the battery does, and at an acceptable current level. First determine the battery output from the ID sticker, then measure the charger output. It must be 1 or 2 volts more than the battery output. If the charger is working, charge the battery overnight. If the battery does not charge or runs down quickly, the battery must be replaced. All batteries have a limited number of charge cycles. The most common problem with Ni-Cad batteries happens when they are re-charged before they are completely discharged. Recharging a half used Ni-Cad sets up a short term memory and the battery discharges faster than normal.

The 705 will operate on (8) frequencies in the 446Mhz range and (5) in the 464Mhz range. The 708 operates on 446Mhz. Please note that the links provided mention they operate in "public frequency band" of South Africa. These radios were not intended to be used in other countries. See below for more. In the U.S.(and many, many other countries), the 420Mhz - 450Mhz frequency range is set aside by the FCC (and other bodies) for licensed operation by amateur radio operators. Portions of the 460Mhz range is set aside by the FCC for use by Public Safety Agencies - mostly local police and fire departments. In the U.S., the Family Radio Service (FRS is 462Mhz) is an unlicensed band and General Mobile Radio Service (GMRS is 467 Mhz) requires a licensed. As you might have guessed, unlicensed or unauthorized transmissions are ILLEGAL. You may be fined, imprisoned or both if caught by the FCC. If using these radios in a location other than South Africa, consult that county's communication authority BEFORE transmitting. You cannot transmit legally in the U.S. with these radios.

The answer is yes (sort of), PROVIDED BOTH OF YOU obtain at least a Technician-class radio amateur license from the Federal Communications Commission (FCC). To get this license, you will need to take some classes, then pass a 35-question mulitple-choice test. You will learn a LOT about your radios, and radio in general, in those classes. Many of the classes are free. Once you've passed this test, you will get your own call letters, which must be used to identify your station (walkie-talkie). You will be able to talk to other amateurs as well as your friend. You will get a lot of other privileges, too. As for the radios, you will need to have them programmed to the same frequencies, to enable you to talk to each other.Contact the American Radio Relay League (ARRL) for information on classes in your area. Talk to hams you might know. You could be on the way to a wonderful hobby...or even a career, if you take it that far!Notice I said, "sort of". These radios would both need to be programmed to the same simplex frequencies, to enable you to talk to each other. As such, you would find them of limited use on the ham bands, and you would soon want something a little better, to enable you to talk over repeaters as well as simplex (radio-to-radio). Fortunately, there are some quite-inexpensive handie-talkies available. Baofeng and Wouxun come to mind. I have a Wouxun, and it works quite well. A word of caution: Do not transmit on the Icom without a license and having it programmed to appropriate frequencies. Also, make sure the Zartek is programmed to GMRS frequencies before using it. DON'T (that is, DO NOT) mess with the FCC, as FCC fines routinely run to the thousands of dollars!!!Finally, if you just want to talk short distances, you can buy GMRS/FRS radios from places like Big 5, etc, for not very much money. You might not be happy with them for very long, though.

Try looking up the user manual at www.mods.dk they have many manuals. Otherwise you may be able to get the manual from www.icom.com.

It's possible because this would allow the RF signal to flood the circuit. I would suggest you try another antenna as a first solution. A bad antenna would cause the same problem. Good luck and let me know if it helps!

What is the actual question? You can get replacement battery chargers from ICOM parts depot, look them up at www.icom.com, or get a universal charger from a local Amateur Radio dealer.
