Hello Nick, I am very interested in knowing what results you get.? My main objectives in not placing it in the Tx path are to reduce the toroid size and to avoid introducing extra mis-match as I

Getting closer ordered mine the 18th

Why replace everything? You can probably put it in place of the 510 (making sure it is pinned correctly, of course). I am waiting on a pair, myself, that I will be stuffing into the ubitx. I want

I might be willing to swap your Ubitx for mine. I haven't touched it yet still new in box. I'm working on modding my bitx 40s for now. If interested let me know we can work out the details. James

Hello, My shipment of replacement RF Mosfets have arrived and I want to replace the on board PASection with one based on the RD16HHF1. It will be a separate small PCB based on the reference design

Hi Chris -? Replying to your suggestion to check DC path.? Unfortunately there is a path to DC no matter if it's TX or RX.? The RX path goes through K1.?? I have verified 12v across D7 (K1)

Jack, Nope, it has its own processor that takes care of the refresh. With the downloadable software you define touch areas, display areas etc. This is downloaded to the onboard processor via

Which display width did you procure for the NEXTION? Pat, VU3PAT

I had a bit of time up my sleeve today, so I have drafted one of the guide pages on the http://www.ubitx.net website: ??? http://ubitx.net/wiring-up-a-paddle-and-straight-key/ I need better

Hi John, Ill get it installed tonight... However, I do have one already installed using T37-6 and tantalum caps that seems to be working fine. It is on the ANT though, So I am hoping puting this new

I soldered it at the board. No issues. Marco - KG5PRT [email protected]> wrote:

Should be fine, only concern might be if your soldering iron was faulty and the tip was not at ground potential.? In fact, installing the 4.7k at the Raduino may be slighty preferred, as there's less

There is a 4700 Ohm pullup resistor that must be installed between +5 V and the key line.? The wiring instructions show it being installed at the key jack.? Is it OK to install it on the Raduino

Hello Nick, This is looking very good. I will try a quick version tomorrow with T68-6 toroids (the smallest size I have handy) in the antenna circuit just to see how much attenuation I get. I am

I believe you will find that the front and rear panels for these cases are isolated electrically from the rest of the cabinet. They nestle into the plastic rim around the front and the back.? If you

I have one on back order. I have the smaller one and I just can’t get the ubitx in it. However it is a nice case so I backordered the bigger one Bob W5rkm

If the IRF510 gate is driven hard with a square wave, it switches fine at 7mhz and beyond, showing a nice square wave for drain voltage (0-24v) and drain current with troughs all the way to zero.?

Jack, I am using the serial connection. No drivers needed. v/r Fred W4JLE Sent: Wednesday, January 31, 2018 14:48 To: [email protected] Subject: Re: [BITX20] Nextion Display Fred:
