Ok, here's the story.
I have an old COBRA 139 which works excellantly on it's own. with a stock mic. or with my cheap power mic. Great radio for local xmit and rec.
Here's what I'm trying to accomplish.
I picked up a PALOMAR TX100 Broad Band 3-30MHz Bi-Linear Amp, hooked it up to a PYRAMD PS-3KX power supply (Fully Regulated, 115VAC, 60Hz, Output: 13.8VDC 2.5 AMP Constant, 3AMP Surge)
for in house use. I also am
using a Radio Shack SWR/Power Meter, going out to a home brew 8'8" dipole, built to spec. ("I've established 2:1 SWR) The Palomar, lights up and when I dead key, reads 150W PEP on the meter (AM
) and of course fluctuates according to voice on SSB
. So the boost is there at the meter, however, people receiving me say that my voice sounds muffled. So, I installed a PARA DYNAMICS PC1089 LOW PASS FILTER, thinking that would help but I still have a problem.
Does the AC vs DC situation cause the interfereance? Should I use an antenna tuner? Is the COBRA's output sufficient for the Bi-Linear to function properly? I have all heavy coax jumpers between the radio, the amp, the filter and the meter, with 50ohm going out to the antenna.
Here's the line-up: Radio>Amp.>Filter>Meter>Antenna.
not a formally trained tech., so if I seem a little dense with my knowledge or lack of it, you'll know why and perhaps be kind enough to assist me. I know that there are many variables when doing this sort of set-up.
