I haven't seen mine in Winnipeg as of today (Sept. 6) for serial #64 Gerry Sherman Sent by the Thunderbird

They are tricky little critters! I had to put two in series for exactly that reason in a uninterruptible power supply/charger system that I designed.

Thanks Jerry, since I know nothing about these devices I had to ask. Max

You can't fully turn off the PFET in this application since the intrinsic body diode allows current to flow from the battery to the rig.? You could add a second PFET in series with this one but this

The trick to searching on Mouser is to select large fields of values for the various parameters. For example, I selected all values of Rds that were 5 mOhms or less by holding the Control key down

Bill, The code is already integrated. Bob, Goody and I are changing the plumbing a bit before we add more modes. FreeDV, js8call and FT4 are at the top of the list. I would also love to do NBFM and AM

Has there been conversation or mention of FT4 inclusion into Sbitx. So much faster and probably cooler on the finals ..... bill NY9H

I'm curious if a switch could be added to this circuit to turn it on and off? Or better still, could it be controlled via 3.3v or 5v logic with a few extra parts? I need an electronic switch and the

One of the simplest ONE component protection is a Polarized Relay. All the rigs I tinkered with in the 80-90s had a polarized relay on the TX final board. Raj

That's FANTASTIC of you, Jerry. Much slicker with the online stores than I had been. I ordered 8 of the IPP80 version just to have a few more around the house since there are hundreds of them -- BUT

Dave, Congratulations on the build! You can also move the IF to 4.915 MHz. It makes the frequency display a little more complicated but it is always a good idea to have an IF unlit by any of the

Dear Members, I just finished wiring up my receiver modules and taking care of this and that? when you first light of any home brew project.? Us Amateurs on this side of the earth have the US

Right now this is intended just to view all the settings. I think Ashhar has some ideas for implementing a settings load function which would enable profiles.

Indeed. I will work on that.

interesting "\settings" - so in the future you could save those settings to a file and implement a settings load function to use them as saved profiles? 73 Lou KI5FTY

The \settings can just loop through all the controls.

John, I do not know the rationale behind needing a full Linux on a Windows PC to run an X-Windows server.? Before finding the VNC option on Raspian (one of the official Raspberry Pi OSes), I used

I see you sensibly did a bulk shipment to the USA and then had them posted to individual addresses from there. Did they also get posted to non-US purchasers? Bill VK7MX

Here's a quick search on Mouser for an enhancement mode PFET with an Rds of 5 mOhms or less and a continuous drain current of 50 Amps, must be in stock:
