the correct message is that (with the correct link): hi i have constructed this linear http://tzitzikas.webs.com/linear__500w.JPG at 160m band. the problem is that the linear gives at output only 300
I would like to ask you if you have a schematic/idea for swr protection, which will cut off the voltage (under high swr) by using a relay. i would like to put a relative circuit after output stage to
hi. i have a transmitter 500w. When i give modulation to the pll i have problems with pll's lock. i believe that the problem is from modulation's coaxial audio cable. I think that it works like an an

I have problem with R.F interference from linear amplifier or antenna to pll unit. I believe that i have ground loops. I have read some relative articles: http://www.radioworks.com/nbgnd.html http://
thank you very much! so material #43 ferrite is improper? i have not other material. _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/
Hi i have a transmittre. I would like to put a low pass filter with Fc about 100khz or lower in transmitter's audio input to cut off the R.F witch is collected from 20meters audio coaxial cable and i
Hi, i have a transmitter 500w. I am using coaxial audio cable to give modulation to the pll. I have many problems with R.F interferences from my antenna or linear to pll. I believe that the audio cab
When i tried to connect my equipment with the ground rod, i have major problems, with pll's lock and the modulation. I have grounded my equipment to public power's corporation ground. _______________
here you can see all of you a schematic from my transmitter installation http://tzitzikas.site90.net/files/temporary/block_diagram.pdf I must use ground rod at the end of RG214 (at the feed point) be
no. i am not http://5-19lamia.blogspot.com/ . i resolve the problem with feedback in my pll. _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contest
