Ahh, Could pipe a little energy from one of the reference oscillators on the Raduino to the RX antenna port for demodulator checkout. Either the 25mhz reference for the Si5351 or the 16mhz for the

RF problems. Try a quarter wave piece(s) of wire for the bands where you suffer interference connected to the cabinet. An old but useful trick

End fed dipole should be good for HF plus 6M but some things have to be done to make it so. Here's the one at my location that I use mostly on 60M and 17M but while it seems to load on 160M, it is not

Remember after each change you have to power down the ubitx and close memory manager -- 73 Mick VA3EPM

All the RF sections of the receiver except the demodulator could be checked out by driving the BFO from CLK#0 into the antenna jack. Need a pretty serious attenuator, of course. Perhaps remove the

Jim, A few posts back I was suggesting that we make use of the Raduino's Nano to drive an Si5351 on the test set board for use as a signal source. A 4th output allows the rig to remain operational,

I built a signal generator using a spare AD-9850 Direct Digital Synthesizer that I had and an 16x2 LCD. It produces a clean sine wave from DC-daylight. That and a step attenuator produce any signal

Evan, Bob, Meanwhile, I think I finally found what I was looking for to replace the rotary encodeur , with an UP DOWN encoder with 2 buttons + ADD a 3rd to validate. It seems cool to me, instead of

I have a SWR meter and Antenna Tuner attached to the rig. The Antenna is an end fed and I have the Balan about 4 ft away from the rig. I had this problem from the beginning. But I work 80 and 40

Evan, Bob, Test made with an other power without earth connexion. it's the same. Click when digit change. last test to do, pull resistor and diviser with capacitors on line TX, RX. cdt

The scan on my Xiegu G90 also has multiple scans and repeats until you punch the Quit button. There are two scan options for Fast and Slow, also. A Tune of the radio then another scan to see the

Bob, you have to use the tuning knob to scroll through the menu, set the center freq and span. then highlight plot and press the encoder knob to start the plot. In the older version it a single scan

Evan ,Bob, Evan, I checked the earth ground of the oscilloscope, it’s well grounded. For the power outlets, both are on the same connection. I checked my home made power supply I built. I see

Jerry, Thanks for pointing those out. I just ordered some for my parts supply. Looks like the price is a 50% off promo price. For just a little more in shipping, less Than $0.50, it can ship Banggood

I know that programming is limited to code limits but this would be a nice V7 attribute, to me anyway... When going to Split, an option on the screen would be "A = B" or, in other words, the operating

Thanks, Raj. I'm still wondering if you press the word "plot" on the screen or if there's a button on the case that is not visible. If you press "plot" on the screen, it must be sensitive to the

Bob, It has SMA connectors two of them. One output and one input. When you press plot, it plots on its own screen. No PC required. No touchscreen. No freq. counter but you can measure indirectly in

This looks very interesting. One specification was not shown, however. In the Antuino write-up, you show it reading the SWR but also shown is the frequency readout. It then acts as a frequency

Jerry, We do sell a test set, it is called Antunio! Except for the dummy load, the Antuino is really all you need to align any HF radio set. It can be used to test any radio well into UHF range as
