I've had a Peaberry V2 kit on my shelf for two years and I am finally building it. I have it assembled through the the receiver section. The receiver works and tunes in HDSDR. I've tested it on 20, 30, 40, and 60 using a signal generator. The problem is the the image is as big as the the fundamental and the receiver sensitivity seems low. I checked all the solders, tried direct injection on C27, and rewound T2. No change.
Using the recording function in HDSDR I recorded some data with a tone 1 KHz away from the LO frequency. I read the data into Matlab for analysis. The amplitudes of the both I and Q are low but they are very close. The phase difference between I and Q is 50 degrees. It should be 90 degrees. Any idea where I am getting a 40 degree phase shift?
