RE: [Repeater-Builder] Re: TPL amplifier - aka repeater operation at the 250 watt power lev

Exactly my thoughts , I would rather use a 30 watt rpt which is clean and sensitive than a deaf 250 watt widebander.. around these parts our rpt average less than 50 watts and can be heard well considerable distances (with lower power which in of it's self is a result of remote locations) T

I guess it's a different world out here in the wild wild west. Very few machines run more than 30 watts. Of course with our 10,000+ foot granite towers we don't need any more. Some machines have 100+ mile (radius) coverage. Keith McQueen 801-224-9460 [EMAIL PROTECTED] -Original Messag

Hello Group! Ive been working with a T-835-20 and attempting to re freq it down in the 143 band. Im unable to get V-Lock in that area. Does anyone have any experience in retuning this model. I did solder the jumpers in that the manual spoke of to lower the band. But that has not has not helped.

Don, Here at Repeater-Builder we have the same problem. Our solution was to re-produce the band-pass filter board and make an adaptor/carrier board for our AP-50 to allow it to plug into the PLL exciter just like the OEM processor. If you are interested in a few of either of these, let me know

Re: [Repeater-Builder] Re: TPL amplifier - aka repeater operation at the 250 ...

There is an additional factor that can cause deterioration of repeater coverage when PA power is significantly increased. It's broadband noise. Increasing PA power increases the intensity and coverage of the induction field which risks stimulating close aboard rusty joints and even dissimil

RE: [Repeater-Builder] Re: TPL amplifier - aka repeater operation at the 250 watt power level

Skipp, It is not just a cautious road to travel; it may also be an unnecessary one. Since repeater coverage is primarily limited by its ability to receive the low-powered distant stations, 250 watts of transmit power may be far in excess of what is needed for a balanced system. Even at sites wher
