Re: [GenesisRadio] Re: G11 not work
- Hi Bruce... GM...I expressed myself badly ... Where written audio signal, meant, RF signal ...The volume of Audio Speaker is at the end and also GSDR.I put my FT-2000 in the frequency of the station, and listen well, but GSDR, even with the total volume in both the computer and GSDR RF Gain maximum also the audio station was very low.I am now with a Delta Loop antenna for 40M in GSDR. So I believe the problem is not the antenna.Sorry I have expressed myself badly ...73 / TUCarlos Alberto-PY4XX2013/7/24 Bruce kf1z <kf1z@...>ALL Si570 need to be calibrated to be on the correct frequency.the audio being low.... well, windows volume controls, the AF and RF sliders in GSDR all should helpfor Si570 calibration see here:Glad you are making progress!brucekf1zHi Goran...Well... My counter is not very precision. I builded the Counter of DL4YHF but show me approximate the value...Where must be 56.080Mhz I have 56.040Mhz +/-Now, a good news... My G11 is listen stations, but.... ( always have a but ... hi hi ) the audio is very very low...I perceived too, that G11 is slightly off frequency.I leaved my other radio in a frequency ( 50.100Mhz ) sending CW beacon with 5W and the G11 received in 50.094Mhz.This may be due to the frequency SI570 be even a little off ?I believe that now missing bit, to put it correctly, and I can continue with the mounting the Kit ..TU / 73...Carlos Alberto - PY4XX2013/7/23 Goran <yt7pwr@...>
You can use very simple test method: with finger (or with small screwdriver or sharp needle) touch points in I/Q chain starting from G11 AF output (sound card input). Entire spectrum must react in chaotic way. If you have small AF signal generator inject very weak, several KHz sine signal and follow I/Q AF amplifier chain up to receiver mixer. Then check mixer and BPF (you need RF signal generator). Small surplus Xtal oscillator from old PC (4-20MHz) will do job just fine. Did you check Si570 frequency?
