Run COR into a 555 pin 2. Invert pin 3 of 555 with 2n. Run collector of for xmit PTT. Need 3 resistors, 2 caps, 1 diode, 1 555, 1 2N. Look at any 555 timer circuit. Put diode from pin 7 pointing to pin 2. (Actually, use COR not.) Of course this doesn't address the time-

RE: [Repeater-Builder] Re: GE Mastr II Power Drop

Does the amp have separate driver and final boards? if so you can take the final board right out and just run the driver it should be good for 15-20 watts on that size heat sink. If it is the amp I am thinking of the driver board is the same board used in MVP and Exec II's there are others out the

[Repeater-Builder] Re: GE Mastr II Power Drop

Thanks guys for the suggestions I do have 2 4" fans on the fins. I do realize about what you and Skip mentioned as well as far as running it below 50%. The PA...being "tuned" (with caps) on the 450 band...really puts out about 55 watts in the 440 band. I haven't ran this pa...but have ran

Re: [Repeater-Builder] GE Mastr II Power Drop

My guess is that its overheating and protecting itself.Are you using cooling fans? You may have a mismatch to the external PA. It is unwise to run any GE PA at less than 50% power,the controlled stage is a driver,not the final. There was a thread on here a while back about impedance changes an

[Repeater-Builder] GE Mastr II Power Drop

I have a UHF repeater made from a GE Mastr II converted mobile. The PA that is in it is a 75 watt turned down to about 20 watts. It is driving a 100 watt amp (30 in 100 out) so it is putting about 75 watts into the cans. The whole setup pulls about 18 amps. Recently I found the power to dro

When I lost my Mastr-II continuous duty PA going into winter, I swapped the board for a 110W mobile from an Executive-II with the TO-220 power regulation transistor, I just gobbed on some heat sink grease and bent the transistor slightly so I could use one of the original TO-3s mounting holes. A

I have a 100 watt micor continuous duty amp.  You would have to turn down your input power to .5 watts though as that's all it takes as input.  Of course I would like to get rid of the rest of the repeater too along with it.  Who knows maybe I can get more for it piece by piece.   T.J.Kevin Be
