73, Miro.

have you already tried to get in contact with the customer service of Funkamateur?
The output signal of the FA-SDR is quite good. So there seems to be a problem with your kit!

I ordered the FA-SDR kit and got it very quickly, within a week. Good service! Another highlight was that all smd’s were pre-soldered on the PCB. All I had to do was to solder axial components in place and other electromechanical components like relays, rotary switches and connectors. It took me one evening to complete the job. With software “Rocky” I was able to receive all amateur bands and the sensitivity seems to be adequate, too.

I also made an one-way contact with my ham radio fellow living about 6 km’s away. He relayed back my 10 mW signal on 2 metres…but it was really a QRPP contact.

Yesterday I received the 1W PA kit. It was also a nice kit, everything was straightforward and now I have the PA plugged in place. I also adjusted the idle current of the PA fets according to the instructions. It seems that I can get one watt or so out of the transceiver.

Which is really pissing me is the lack of instructions how to adjust the trimmers on TX chain. Nothing seems to happen when adjusting those damn things. There is a table which suggests to adjust them to certain voltages on a couple of bands but I think it is not enough. I also find the PA output very dirty. How do I adjust the phase and amplitude to get the mirror carrier at minimum, that’s the problem.

Can anyone help me please.

I’m not aware of any webpage / article which is comparing the FA-SDR specifically to other SDRs, but be assured that the measured results are very competitive.

Regarding the Amp: Harald, DL2EWN also published recently an article about a very linear 5Watt QRP PA. The kit is also available from Funkamateur at: http://bit.ly/9uaKJt

Thanks about your website and your newsletter

1 – I ordered a full Fa-sdr kit and i’m waiting for its delivery with impatience!

Do you know where we can find some feedback and comparison between Fa-sdr and the others SDRs ?
Are the users satisfied ?

2 – Do you know if an RF amplifier for increasing power to 15/20 w is in progress ,

sure, I’ll be glad to help, however I’m not sure if I understood your problem correctly. Could you please try to explain the software and the hardware problem to a little bit bigger externd? As far as I know, there is no English manual available until today. However it’s always a good idea to check directly with the kit producer at http://bit.ly/9riHtn
