I can see me messing up those I will rewind for grins. Tim

*** Does it tune smooth? No ticks? - Jerry, KF6VB

Doesn't the newer RF board have the solder holes in the middle of the attenuator pads? - Jerry, KF6VB

-78dB? My V11 : with HC125 buffer, no shield on display, and 12V switching power supply

That’s not bad… there is some low-level noise on the signal at about 400 hz and I wonder what that is? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner -

John… This is good work. I just ordered the parts for the Display Driver kits after I got good reports from 4 of the 5 kits I sent out for people to try. The parts for the remainder of the Drivers

What is coming out of the QSE after the BPF? The PA will amplify pretty much everything from 1-150 MHz (at different gains). If the input is not clean, the output won’t be that clean. Dr. William J.

The noise floor for the current V12 radio is better than -100 db as measured without the driver chip… My V11 with the buffer chip is nominally -78 db. That is ok for a test platform (toy level) but

Have you got a block diagram of this/ signal flows. Its something to contemplate vs. a FPGA and a Teensy. I’m formulating my next steps and want to get the next step absolutely perfect. Dr. William

May be a bad cable or on the wrong cable (remember… there is WINE, WIRE1, and WIRE2…. Three channels for the I2C comms so you gotta be on the right cable. See the development document on the

Thanks Oliver. I'll redo the tests next week. dave [email protected]> wrote:

The frequency calibration of my HackRF One is a little bit off, but here's what the audio sounds like from my radio (see attached WAV file). I haven't done anything to try to improve the mic.

If I connect a broadband power meter to the output of my radio I measure the following: State Power [dBm] Calculated RMS Voltage [V] Measurement configuration PTT not pressed -47 9.99E-04 No

Just a reminder that I will ALWAYS send out an invoice for boards and kits you order from me. Wait for the invoice. NEVER send me money without an invoice because it messes up my accounting system and

The only think that has changed on this list is the RF board… and that change was just to remove the divider circuit for the low-frequency operation that can now be done in software. The previous

I have four of the PA kits built here and I get a gain fluctuation of +0.2/-0.8 from 1-54 Mhz inclusive after a little tuning of the capacitor across the T3 primary. You might check to make sure you

Thanks, Todd...it's appreciated! Jack, W8TEE

Thank you, Jack and Al, for this labor of love! This has been a monumental contribution to Amateur Radio! 73 de Todd W2TEF

I am getting about 50mv noise out of the 20W amp in SSB with PTT engaged; no mic plugged in.? I'm running version 66.9 and am all calibrated.? Additionally, when PTT is engaged there is a burst of
