Re: Amateur HF Radio TS-140s
There is no reset for the transmit power. the only thing that effects the power is the slider control on the right hand side of the radio that is marked "PWR" and the ALC/PWR switch located under the clear button.

This would depend on which area of radio you are asking about. In FRS/GMRS there is no "low frequency" though some manufacturers may use those phrases. FRS/GMRS radios are all in the UHF range, or ultra high frequency. In amateur radio we use UFH, VHF, and HF or high frequency. Though the FCC does not allow amateur use of the LF range, there are experimental stations that are allowed to operate ther. See http://www.arrl.org/lf-low-frequency for an explanation of this. For an understanding of the range of frequencies and what is UHF, VHF, HF, etc. see the chart at the lower part of the page at http://en.wikipedia.org/wiki/Radio_frequency
This is an Amateur (Ham) Radio 2-meter Transceiver. It will only transmit on the 2-meter Amateur band (144-148 MHz) but has expanded receiver coverage from 136-174 MHz which includes Public Service and Commercial 2-Way Radio bands. Please note that an Amateur License is required to operate on the 2-meter Amateur Band.
Hi Andy, What you have is an amateur radio which requires a license to operate it. Having said that, I don't know where you got the unit from, but obviously, the unit has had the frequencies deleted, so you cannot operate it until you go to a radio workshop to have the unit re-programmed. You will only get receive(RX) frequencies programmed, no transmit(TX) frequencies. Sorry, but if you want to operate this unit, you will need to approach the Wireless Institute of Australia(WIA), who are responsible for licensing of radio amateur operators in Australia. web:www.vk6wia.net for all the info re: licensing requirements.
The best I can come up with is Try this: join yahoo group Specific to your radio Make/Model, the experts there will help you with useful info and you can download manuals, schematics and software, if available, for your radio and all this is free.
Firstly, I take it that you are a licensed Amateur operator, if not, you're breaking the law.
If, on the other hand you are licensed, then I would contact a friendly Ham operator, who would be only to pleased to assist, after all, Amateur radio operators spend most of their time doing just this kind of thing, as you well know, if you are indeed a licensed Ham operator.
Firstly, are you a licensed Amateur Radio Operator, if not, you are breaking the law buy transmitting on that frequency. The Amateur 2 metre band, which covers 144 - 148MHz is for the use by Licensed Amateur Radio Operators ONLY.
You are free to listen to these frequencies, because you are a listener, and the radio is being used to receive ONLY.
But you CAN NOT transmit on these frequencies.
If you get caught, you will be charged under federal FCC laws governing the use/misuse of radio equipment and a heavy fine &/or imprisonment can be expected. YOU HAVE BEEN WARNED!!!
You can increase the power supply to 15 Volts, but your rig is small to dissipate the cold air inside. Place a small fan in the rear. You not need more power and the difference is barely disguisable to the other part. Put your effort in a batter antenna. Regards. Edgardo LU1-AR
