I always match my resistors and capacitors as well to make sure I have a good balance. It wouldn't be a bad idea seeing you have to rebuild it. I use 1% resistors and 5% capacitors. Use your meter to find the components that are as close as possible. Good Luck !
You have 3 transistors for your AM mod amp. Use a voltmeter and take some measurements in AM mode on these transistors and compare with what I have below.
TR49 Base 6.10v in tx
Collector 12.10v in tx
Emitter 5.6v in tx
TR50 Base 12.10v in tx
Collector 5.60v in...
Physically they will drop in but the electrical characteristics are different. You would have to change input and outputs to accommodate the higher collector to emitter and collector to base voltages on the MRF454's. The MRF455/SRF2072 will work fine.
Here you go. 1 pic is of the 8 element quad on the ladders waiting for the crane to lift it up on the tower. 2nd pic is of it up on the tower. 3rd pic is after the ice storm. You can see the ice weighing down the spreaders and wires...lol
Just copy the LIGHTNING 4 element quad. Its a true full wave and beats any other quad out there. IMO I had an 8 element quad up north that part of the 42 foot long boom broke in half from a nasty ice storm. I was sent a replacement boom section and ended up making 2- 4 element quads from it. I...
Talked to a few stations in Texas this morning using a stock Galaxy DX-98VHP. It is a customers unit that was in for repair. It has rockin audio but hey, it's a typical Galaxy and needs the clarifier turned every so often to stay on frequency.
Tr36 must have 8v on the collector in receive mode and 0v in transmit mode.
Tr38 must have 0v on the collector in receive mode and 8v in transmit mode.
Please double check these and post back with your findings.
Yep. The MS-119 made by Antenna Specialists. A really nice antenna. I used to run one up 110 feet just outside Toronto. Still have one spanking new in the box and no it's not for sale :) I got that and the M-134 "Mariner" 5 element beam from a storage unit sale. The Mariner is what I just put...
I just picked up the export version with FM. Just finished recapping it today, actually. Going to start the alignment on it in the morning. It has the Hi/LO toggle for extra channels.
