Thanks Alan for the tip with the dummy load. Will build one to do a few tests on the WSPR. So I turned on the WSPR with my Antenna on and everything. Also did the programming as I had it before and it

Stephan, This dummy load http://qrp-labs.com/dummy.html has a power measuring circuit and instructions how to use. You could copy it, make a QRP one. As the others said when bias is set to zero 70mW i

Hi Guys, Thanks for all the advise and options that I can still try. Just an update on a few things. The GPS is connected to the Ultimate3S. I had a thought that this might have caused this in the beg

Before you start pulling the rig apart, keep it simple. Why do you think that the processor might be faulty. The timer counting up is indicative of no GPS signal to give timing info. If you don't have

Stephan You didn't mention how you are measuring power, and our meters can vary from one another. I am using a WM2 power meter designed for qrp, I won't say its perfect. As Andy mentioned, do check th

Hi Stephan, The counting is simply because the time has not been set in the menu, I assume you are not using the gps? As for power, this could be a number of things, check that you have it biased prop

Hi Guys, I have a very weird problem with my Ultimate3S. I have build everything together and started to transmit on 20m which was great. A few people could get my signal which was great. Did not have

Matt I am using a commercial EFHW with my 80m QCX+ (its from myantennas) - no issues operating with or without the matching PA (at about 20 watts) - but I do have a ground rod near the transmitter loc

I had exactly the same happen on my last SOTA outing. SWR was around 2:1. I couldn't fix it in the field, but set up the same way at home, a few loops of the key lead around a toroid fixed it. Then I

Thanks for the quick answer. I have plenty of ferrites at home, so I can knock up a CMC choke no problem. I was actually outside using a Fuchskreis antenna tuner, which I assumed would not suffer from

The "G" is the QCXs way of indicating that it thinks a GPS is connected and puts the radio in the GPS mode which locks the TX. The keying circuit and the GPS share several pins. As mentioned above, if

The common misconception is that the end fed half wave antenna with a 1:49 Voltage transformer does not need a feed point ground or counterpoise. That is false. In order for the transformer to properl

Hi Matt It means RF is getting into your keying cable. You can solve this by winding the keying cable around a ferrite toroid. Even better would be to solve the common mode current problem which you p

I was testing my QCX 80m today and had problems on transmit. After a few characters, a G would appear as the last digit in the frequency and the QCX would lock up and only transmit an E every five sec

Mark, Were you able to try picking up the 27 MHz signal on another receiver? I checked mine and had to hold the tip of the PL-259 connector about 1/2" away from the synthesizer chip. If not, you might

I am going to replace the 27MHz crystal. It should be here in a fews days. I will also call my local store and see if they would be able to assist with an oscilloscope. I'll post some updates when tho

Mark, The message simply means that there is no communication between the Si5351 and IC2. IC2 is working. IC1 is not. Yes, listen for the approximate 27MHz, often around 27.004 with a RX. I'm not sure

Thank you guys again for your suggestions, I've tested the radio under a few conditions. The radio does not work after being powered on from cold (room temp without having power connected), all I get

Hi Mark, Do you think it might be heat related? If you leave it sit off for awhile, will it work for a short period before resetting and failing? Do you have a can of compressed air, like the ones use
