eb300-
Slawomir: Hello All, I ran SDR Angelia + eb300 PA. Order protect platine it contains error. There were no mounted ohm resistors 100 (R19 and R24). After their installation work and protect HiSWR PA does not want to key a PTT. I had to break the circuit unsoldered diode VD12 PA and now works ok, but the lack of protect. The second problem is the interference voltage of 12 V. SDR has its zailacz 12 V and eb300 also has a power supply 12 to TIP122. By DB25 cable is not served 12 V and yet without connecting 50 V for eb300 LCD lights up. Voltage probably passes through the control code BCD LPF in the EB300. Please colleagues who have such an amplifier for help in solving my problems. We are happy to talk on Skype. I know a little Russian language. My SDR and eb300 you can see on my profile QRZ.com. 0 (0.00%) Greetings from Wroclaw. 0 (0.00%) Slawomir SP6DLO
