after a damage, I want to change my amp from DX-Patrol 12W Amp to a SG-Labs Modell. V2 has an Input of 500mW and the new V3 max 100mW. I look for the V3 Version but I don´t not know If I can reduce the DX-Patrol-Upconverter to abt 40mW out with the inside power adjustment.
Has anybody test the UpConverter V3, how deep you can reduce the output of the upconverter Version 3?
Although this is a thread from 3 years old, i can enlighten you with some information. I blew up the PA from my DXpatrol QO-100 groundstation (old version) and was also thinking of replace it by a SG-Labs V3 one.
The output from the DXpatrol transverter board is about 25-60 mW (P38). That is a perfect powerlevel for the SG-lab PA (max 50mW input). I tried already in lose components at the workbench, and it gives 12 real watts to the antenna connector at 24 volts into the analyser.
The original DXpatrol claims 10-12 watts, but I have never seen that on the analyser. 7-8 watts at highest level. For the extra PTT/VOX pin on the SGlabs is no need to connect somewhere. If the readings at the front are matching, I have still to discover that, drill the extra holes in the SG-labs ans so on.
Maybe someone out there is searching for this modification and can now find a acknowledgement for doing it .
My extra 2 cents:
An extra thought is placing an extra Chinese small amplifier PCB and an extra PCB fingerfilter and push it to 20 watts. But I suppose that it then suffers from enough cooling in the standard box.
