The GX3200 allows you simply broadcast your DSS, DVDs, music, CDs, Satellite, Gaming console, [...]
The schematic show you a RF amplifier with very high gain. The feeding RF signal enter C9 to transistor Q1 which has a self biased working point. The gain and working point is set with the two resistors R1 and R2. FB1, C5, C6 works as filter for rejecting RF to power line. Q1 has a gain about 15dBm. The output signal can be found a the collector which then enter a second amplifier stage Q2. This stage also has a self biased working point. The gain is set by the resistors R3//R4 and R5//R6.Why do I have 2 parallel resistors like that?It is because I want to be able to change the gain of the amplifier. On the PCB below you will see that I only have 2 pads for the resistors. When I want to resistors I solder the two resistors R5 and R6 on top of each other and the same with R3 and R4.I advice
More photo goodies!If you've been looking for an alternative to the expensive Pocket Wizard radio flash triggers that currently rule the photo universe, you might just have a new 'expensive' option coming in the first weeks of January. Radio Poppers from Kevin King, Phoenix Arizona based wedding shooter, promises to be a revolutionary new transmitter / receiver flash trigger for working with E-TTL and Canon / Nikon cameras. His tiny Radio Popper receiver units promise more flexibility with shutter speed sync, increased transmitter working distance and flawless reliability in bright daylight. You can read more about his Radio Poppers on the STROBIST website, where you can follow links to an original article from September of this year.There still seem to be a lot of skeptics and Pocket Wizard true-believers out there who want to cast doubt on his invention and scheduled January 2008 release date. You can check out the Radio Popper Website and decide for yourself.* If you're readi
