[amsat-bb] Re: How the Amateur Radio OSSI-1 Satellite Works
Unless I missed it, the LEDs appear to be just 'light'. Had they turned the LEDs on and off at a defined audio rate, the signal could have been detected with a soundcard with a waterfall display giving an increase of x10 in sensitivity. Love the supercaps though. (vacuum tested?)

[amsat-bb] Icom AG-35 Preamp Question
I bought an Icom AG-35 preamp about a year ago. The fellow ham advertised it as virtually brand new and it was/is. I planned to use it this summer with a TS-2000 which doesn't supply 12v voltage to the coax to power a preamp as other xcvrs do. I used a Mirage KP2 unit to inject power to the coax to drive mast mounted the preamp. When I turn the power on there seems to be little or no noticeable difference in background noise and worse than that I cannot here any signals on FO-29 downlink, and I know the bird has been active. Any suggestions? Is the preamp fried? I can't even get the weather proof case off to trouble shoot, not that I'd know what to look for. Any suggestions on repair?

[amsat-bb] Re: Icom AG-35 Preamp Question
First, make sure that nothing else that might block DC is in line between the power inserter and the preamp. Then, have someone go up the ladder and listen as you turn the power feed on and off. They should hear a distinct click as the relays in the preamp engage. Tune to a distant repeater, and you should see at least a 2 - 3 S-unit increase when the preamp is on. How much current is the KP2 capable of supplying? If it can't pull in those relays, the preamp will remain in bypass mode.

Hi Rick Check the KP2RC unit output volt if it the same as the input supply volt ! This volt suppose to be same on both the input and output coax connectors of the KP2RC control unit . Check the RCA phone jack at KP2RC unit if there any bridge or metal twist any short in this jack will drop the output volt to Zero .

[amsat-bb] Re: Icom AG-35 Preamp Question
Rick, I suggest you use a VOM or DMM to measure the current drawn on 12 volts going to the power injector. If everything is connected correctly It will draw 30-200 mA. Confirm that you have continuity in your coax. Some lightning arrestors have a DC block built in. It is best to test it with a short run of coax between the preamp and the power injector at the radio while listening to a local repeater to see if the signal increases when you apply power to it. If it operates then you can proceed to determine if there are problems with the coax to the antenna, not carrying the 12 VDC. 73 Art, KC6UQH -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of Lawn, Richard Sent: Saturday, August 11, 2012 3:30 PM To: amsat-bb@amsat.org Subject: [amsat-bb] Icom AG-35 Preamp Question I bought an Icom AG-35 preamp about a year ago.
