Difference between high and low frequency


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

VHF/UHF RF Power falls to Zero when the Auto ATU tunr logo is on the display. When the tunr logo is off the VHF/UHF RF power is only 10 watts on 2M and 3 watts on 70cms. The Yaesu FT 857 D should have no...


Check for open or shorted Veractor diodes and steering diodes there may be no direct interaction as you say but if a diode is open or shorted the RF circuits might still be selected for the higher bands and the lower output power on your vhf/uhf is an indication of this.
If you do not have a service manual you can get one hear, you will likely kneed one

TV picture freezing


digital signals do not fade out and get snowy like signals used to do ... if the signal gets too weak then it just freezes .. you might say its either perfect or frozen .. sometimes it gets blocky .. where some sections of the screen freeze while other sections continue .. what that means if you are using an antenna is .. you need a better antenna or better aim for the one you have .. outside is much better than inside but just rabbit ears are ok for strong signal areas .. you can aim the antenna based on a signal strength meter usually provided in HD receivers in the setup menu .. you can also get an antenna map from "www.antennaweb.org" .. that will show you what direction to point the thing for each channel and how strong each channel should be ... if you are using Cable instead of an antenna then you should have good signal strength but there is a problem called "Crest Factor" .. that becomes an issue when they put too many signals on a given cable .. the cable handles it ok as long as there is no damage (bad ends, water inside, animal chews, corrosion) but the cable box or receiver may be overloaded as thousands of signals drift in and out of phase ... thats a cable company problem that might be getting worse as more channels are added .. the results are that periodically the picture will freeze or pixelate .. you probably have to accept a little of that but more than a little gets really irritating ....off the air reception with an inside antenna (like rabbit ears) you will find that moving around the room can effect the signal for channels in the UHF range (most are) .. aiming the antenna and getting it as high as possible will minimize that problem.. make sure whatever antenna you use is designed for UHF as well as VHF .. the little circle often found between the two "rabbit ears" is actually the UHF part of the antenna .. it can be rotated for UHF channels while the big ears are aimed and adjusted for VHF .. antennaweb.org will tell you which is UHF and VHF ..

Yaesu ft 50r


The FT-50R is an extended receive, but dual band (UHF & VHF) amateur transceiver. It is capable of transmitting between approximately 144Mhz - 148Mhz VHF and 430Mhz - 450Mhz UHF.

Typically, the radio will provide an audible warning whenever attempting to operate outside of its intended range(s). The manual has a section on maximizing battery life, and can be downloaded below:
