You need to calibrate the rig by setting the correct crystal oscillator freq. this is done more or less trial & error. It is a bit easier to do this by listening on another RX. Hans has a GPS RX that

Unsure of how to do that. I don't see it in the manual.

Did you calibrate the vfo frequency? justin.maynard27@...> wrote:

Nice job. You might want to consider adding ?some air vent holes around the 7805 regulator and also the three final amp transistors. -- 73, Bernie, VE3FWF

I just finished by 40m QCX and looking at the reverse beacon network, when I transmit my callsign on 7030.00 I am picked up on RBN at 7069.3. I have tried the factory reset and re aligning the radio.

Pat, Thanks for the info.? Mine is in the second batch. Ordered 5/31.? Vern

Vern, I ordered mine on day one, 5/29 out of the first batch. All I know is that there was a small stock left of the original 85 after my order was accepted. Once shipped, there was a tracking number

Pat , Do you remember how long ago your ordered your QCX case.? Did they provide a tracking number? I only have a PO box and check my mail once a week.?? I would hate for it to arrive and sit there

I mounted the GPS board within the U3S enclosure but brought out the antenna connection to an SMA and used a packaged GPS magnetic mount patch antenna (did not use the component patch antenna supplied

My idea to keep the gps with the U3S without adding heat to the U3S enclosure.

Nice! Roy WA0YMH

Hammond transparent blue box. Advantage: no display window is required.

Thanks, Hans. I appreciate the explanation and the fuse byte data. Gary brought his rig over tonight and we were able to get the MCU going with your help. He still needs to align it, but he can move

Erik The detector will receive on all odd multiples of the LO. However, as it is a sampling detector it means samples are missed. Even at 3 times the LO sensitivity is down by almost 9dB. 73 Alan

Thank you.? I'm working on your suggestions.? I appreciate the help, and I'm going to look closely at all of them.

When experimenting with BPF I noticed the receiver module will receive a station transmitting at 15.4MHz when tuned to an LO of 1.03MHz. Of course only when using a well tuned BPF to get rid of the

Tony, you may want to just cut off the old caps and solder new ones onto the pads to minimize potential damage to the pads -Steve K1RF Sent: Tuesday, June 26, 2018 9:23 AM To: [email protected]

Tony, N0PBA, no, you need to lower the value of C21 and C22 so paralleling additional caps with the originals will not get you there.? I also suspect that DC leakage that are a characteristic of

If you perform a RESET and follow Hans directions in DIAGNOSTIC mode there is a procedure to follow to fault find this. 73 Ken G4APB

In answer to your original question, manual entry of the maidenhead locator is for when you DON'T have a GPS connected. Once you add the GPS and select it in the menu it will automatically
