Display Advice
After a year of emergencies, I am back at trying to put together a T-41. I purchased the following display from BuyDisplay.com, but do not know if it will work with the T-41. Also, I got the new Display Driver from Bill and don't know if I need that for this device.? Any direction or advice will be greatly appreciated.
I search for the data sheet on BuyDisplay's website, but only found different models. I wrote them, hopefully they will reply. Thanks in advance.? Low Cost 7 inch TFT Touch Display Module for Arduino I2C/SPI Interface

Re: lpf l44
开云体育I used #20 PTFE for the single winding (carries the RF current) and #24-28 transformer wire for the secondary windings.? Its actually not that critical.? I used PTFE wire for the primary because I built the transformer for 100W.? You could use just regular hookup wire for 20W. ? ? Dr. William J.

Re: Kits and parts.
开云体育Ok John… I just sell the latest T41 V12 boards and semi kits… not full sets of parts.? Justin AI6YM sells Kits with all of the parts… but I don’t know how up to date his boards are (need to ask him).? In any case here is what I sell below.? I’m in the process of prepping for HamVention so have closed sales until I’m at Hamvention (and FDIM).? If you attend HamVention or FDIM you can see the stuff first-hand before you purchase and you can get it on the spot (not paying shipping or PayPal fees).?
