      Hi Gang,

      Yesterday I was at a very cold field day station with my softrock Mk.3 rig. It was the first outing for the integrated SDR-widget.

      The system is built into one box, and has a single USB cable connected to my laptop. So with the antenna and power supply, only 3 cables are needed to run it.

      I placed a photo in the files section under M0RZF.

          Very neat indeed. It's a pity the 20W amp is discontinued, especially
          the boards.

            Hi Sid,

            I would be prepared to sell the Gerber files, at a negotiable but reasonable fee, to anyone that wants them.

            The PCB had just one small track error on it, which took about 10 seconds to correct. It's a shame the technology I designed for the amplifier + lowpass filters got wasted. But using the RD16HHF1 FETs makes the price too high compared to designs using SMPS FETs.

              Hi Sid, Rob et al,

              Looking through my pile of unbuilt kits, I do have an unbuilt (but envelop opened) 20W amp kit (without LPF) from Rob.

              It has the pcb plus all the parts for the amp, but NOT any of the LPF components. I paid US$80 for it. I am willing to sell it for US$80 + shipping cost from Singapore (estimated shipping cost to USA/Europe about US$15, uninsured).

              I intended to use the amp with my own switched LPF bank for 160-10M coverage in 7 band groups, rather than the 4 band groups with the 20W PA kit. That's why I did not order the LPF parts from Rob.

              The reasons I have not built up the 20W amp are (1) I have been busy with the sdr-widget project, and (2) I find that I can operate without a 20W amp!

              The 20W amp is a very good complement to the stock Softrock v6.3 RxTx which has a 1W output, and I think it is very good for even the newer Softrock RxTx ensemble kits with about 1W output.

              However, several developments happened after I have purchased Rob's 20W PA kit: Mobo v4.3 and WSPR.

              Now I am operating with my SR v6.3 + Mobo v4.3 combo. The Mobo v4.3 has 5W output. So it works very well as a QRP rig and for WSPR.

              For QRO DX work, I connect the SR/Mobo to an external 600W PA (The EB104 from Communications Concepts). The EB104 has 22dB gain, so with the 5W out from the Mobo, I have almost full power output from the 600W PA.

              So for my setup, there is no need/place for the 20W amp which is caught in-between 5W and 600W.

                    Strange that as I have one of each amplifier sitting on the shelf waiting for me to finish the the matching LPF board.

                    Have you tried them with a Softrock or are using them with the Star radio.

                    I have filter sets around, so that's no problem.

                    I ve seen the 20dB attenuator on the LPF schematic. I ll first work out how much attenuation I need as I have a 0 - 59dB switched attenuator box I built many

                      I've seen the 20dB attenuator on the LPF schematic. I'll first work out
                      how much attenuation I need as I have a 0 - 59dB switched attenuator box
                      I built many years ago.
                      Eventually I hope to use the 20W PA to drive the AN762 with built-in
                      LPF's and to use the rig barefoot for driving the EB104. Many rigs on
                      hand, so the AN762 and EB104 can be switched between them.

                      The AN762 datasheet does not give any figures for input drive power, but
                      I calculate it's around to 20W input for 140W out.
                      73 ... Sid.
