Don, do you have a way to download the PIC programming with a PICKIT3 and compare it to what the programming is supposed to be? I have checked, found errors in, and reprogrammed a couple others' units

Mine does. It starts out red and changes to green. It changes to red on CW transmit. It flashes red with the CW in the beacon mode. 73, Zack W9SZ

Sort of a combination. I removed R200 and L4. I put a jumper across the pads that are for R47 and C47 instead of the blue wire VA3TO showed. I also put a 68 ohm resistor across the OCXO input connecto

Hmm ... that's interesting. I ordered two boards, which I received last week. I did the OCXO mod on one board and swapped the bad one in my box for the new one with the OCXO mod. I put the 20 dB horn

I didn't do the exact mod that VA3TO did. I removed R200 and L4. I did not put in the blue jumper wire, as it appeared to bypass the R45 and C40 (or R46 and C41). I just put in a jumper across the pc

Looks good Don. Very similar to mine. 73, Zack W9SZ

I was wondering this, too. Have any modifications or improvements been done to the circuit in the boards that were just sent out? 73, Zack W9SZ

I received mine. Thanks Tim! 73, Zack W9SZ

I built a 76 GHz station but don't know if it works or not. Nobody nearby to work. I used a DB6NT basic harmonic mixer board. Probably just microwatts out and no receive preamp. 12 inch dish. Since th

You can at least look at the path on Radio Mobile (or Google Earth for that matter). You're most likely not going to work someone if there's a mountain between you and them. 73, Zack W9SZ

Is this just a path loss calculator using distance, or is a terrain calculator? The thing I like about Radio Mobile is that it uses .hgt files (data from the Shuttle Radar Mapping Project) and calcula

OK thanks, Mark. I have seen people ask for boards with parts mounted and just wondered if the board had anything on it I couldn't handle myself. i do a LOT of surface mount construction and have sold

What parts need to be mounted on the board? I haven't been able to determine that. Any SMD IC's with over 40 pins? 73, Zack W9SZ Virus-free. www.avast.com

I've used it through 24 GHz and it seems fairly accurate for paths with no enhancement. As with any similar programs, some band enhancement can change the whole scenario. 73, Zack W9SZ Virus-free. www

Thanks Tim. Still lots of time as far as my use is concerned. My microwave operations won't start until the weather warms up some in the USA and will possibly be curtailed by COVID for a while. Will t

Can I get one board? 73, Zack W9SZ

No, enabling the PTT and the Keying line at the same time puts the unit into beacon mode and it will send the call of whatever is programmed into the PIC in the module. You can hand key it or use an e

If you have a PICKIT3, you can update the firmware in the board to allow you to change the callsign in the CW beacon via the RS-232 port. Or you can just change the callsign in the assembly language c

The file I just uploaded isn't chopped off for my PDF viewer. I think it should be readable OK, It's in the main Files page for the group. 12-OK1DXD_GPS disciplined XCO.pdf Zack Virus-free. www.avast.

If it's what I think it is, it was the MUD 2016 Proceedings, which I put together. I also have the PDF. I will upload it to the group files. 73, Zack W9SZ Virus-free. www.avast.com
