Thanks to David, Don and Gary for making me feel better this morning about my resistors. I have been testing each prior to installation but when came to that group, got lazy and decided to only check them AFTER installation...which then made me wish I hadn't gotten lazy!!! Great object l

Hi David I do not see any problem, at least for R6, 7 and 8. You have an M 10 db attenuator and mesuring R6 or R8 you have 100 ohmswith 168 ohms in parallel. So the result should be 62.68 ohms on you DMM! R7 is 68 ohms with 200 ohms in parallel so you should have 50.74 ohms! So as the series of

David, I am not sure how best to put this... Imagine you put a resistor of infinite value in parallel with your 100 ohm resistor and measured it at the ends of the 100 ohm resistor; of course, you would see the 100 ohms; what if the two resistors were 100 ohms each? well, being in parallel, y

David, Most all the resistors in the K2 (including R20) are 1/4 watt. The only 1/2 watt resistors on the RF Board are R50 and R58. To the best of my knowledge, all resistors shown in the schematic that are NOT 1/4 watt are designated with the power rating. In most cases, a 1/2 watt can be
