I built the sequencer on basic copper strip board and added four relays and “jumpers” so that for each event I could either switch the line to ground, provide 13. Description. 3; Amplifier is now up running, hope it can withstand the harsh handling when I participate in NAC and hunting DX 🙂. The RF filter board sits on top of the main heat sink.

The specific control board discussed in this article, the GE WR55X10942 is commonly found in side-by-side refrigerators, and likely familiar to many readers. 2 with the exception of adding the 20-pin header connector, and substituting wire holes in place of the solder-to surface mount connection points. Am in constructie echipamentul pentru banda de 1,2cm, bazat pe un modul Wavelab ODU si un control board care contine PLL-urile, IF-ul si partea de alimentare, varianta PA0HME. When I assembled this, I used different values for the MMIC bias resistors to match up with my control board (8v for the L. PCB Circuit board, TC-350 material available through www. Thi is just a simple Zener diode Assembly Guide for the 70 CM 500W Amplifier Kit (using the BLF184xr) First, locate the 35pf trimmer capacitor supplied in your kit. 00 471. The main control board is also a circuit board, like the user control and display board we just mentioned. A 6 dB attenuator in the RF path is made up by the combination of R1 and R2. 5" by 4. Designed to pull a control line to ground (up to 28v @ 300 ma max) Event 3 is used by the control board to block RF from the driving radio at critial times (when antenna relays are switching state). 00am-12 Noon on Saturdays. • No Boards will be produced, however those Here is the all new custom 2 Meter Kilowatt Linear Amplifier built and designed by Jim/W6PQL.
