This video shows the details of adding a switch to the HF Packer V4 Amp to switch between CW and SSB mode – which was normally selected via an internal jumpe…

Another most enjoyable, video, Alan, your channel is the only one of two
sites that appeals to me the other is a UK fellow radio amateur . As a
Radio amateur and hobbyist I enjoy the building circuits, so please don’t
change your format. I want to build a simple tracking generator , do you
have any idea’s of circuits that are around please.
What do you want your tracking generator to track?
Yet another excellent video Thank you
I don’t play in the ham world but I like your ham videos for general rf
info. If you didn’t have that watt meter could you check the power with
your oscilloscope or spectrum analyzer? I used a spectrum analyzer once but
it seemed like the info was relative and hard to quantify.
An
Are you doing high-side switching, low side switching, or maybe
bidirectional with an H-bridge?
Hey, could you please do a tutorial about driving MOSFET transistors
properly using TTL PWM signal? Can’t find a decent tutorial about that
really and I’m in a middle of doing a project that involves driving a big
24V DC motor. I’m sure that alot of people would find it useful. Thank you
in advance!
Really nicely done – But wouldn’t you recommend the use of the PTT input
over the RF sense anyway? A cable to the TRX with an integrated reed relais
with integrated diode is done quickly..
It comes down to personal preference, especially considering how much gear,
wires, etc. to pack when running in the field.
Thank you! This will be a great help.
Actually I will need a bi-directional control but I planned to do that
using relays. I think that H bridge with 4 MOSFETs would be a better
solution though, I will control it using PWM signal from Atmel’s ATMega
microcontroller.
Yes you could, but you would have to be especially careful about loading,
impedance matching, etc. And, you would most likely need appropriate
attenuators to bring the power level down to a safe level that will not
damage the scope or spectrum analyzer (especially the spectrum analyzer)
Alan, this third video brings everything together. What a super job. 73
I’ll add this one to my list…
