Hi all, I have tested a mic compressor based on the VOGAD SL6270C (same schematics of its datasheet), and it works very well on the ILER QRPs. However when connected to the ubitx something weird happens. It works the first time I push to talk, I can talk also 5 minutes, and no problem, BUT when I release the PTT and then press again, it does not transmit anything. I did not remove R60 and put an electrolytic cap (the positive towards the ubitx) in the cable connecting the VOGAD and the ubitx. The VOGAD is always powered on via a battery or the same power supply and is DC isolated from the Ubitx. In fact the interconnecting cable also has an isolating transformer to avoid any possible ground loop. Should I really remove R60? Should I remove the DC power of the VOGAD each time I receive? Or should I simply add some polyester caps in parallel at the mic input?
