No problem...thanks for buying it!! Jack, W8TEE

Yes Chapter 20 is included. My mistake. Tom Mongold W8DLR

Did you mean Chapter 20? If so, good! Thanks! Jack, W8TEE

Jack: I ordered the book on April 12 and received it on April 14. It has the black T41 on the front plus chapter 12. So I am good. Tom Mongold W8DLR

ALL: Has anyone received a copy of the new T41 book? The new version supposedly became available after April 4th and has a black T41 on the cover and Appendix C on Calibration has been expanded to a

Hi Harry, Thanks for the note. I just checked my records and I sold a total of 218 full sets of V10/V11 boards (plus odds and ends of full sets). But that was two plus years ago. I may still

Thought putting together a simple schematic and some notes would be easy.? It involved way more than I expected. Attached is a zip file of a package of information on how to construct a test stand

I came across the attenuator problem chasing another problem ... probably didn't need to change U21 and U12 ... Thank you all for your help. Tom

Found issue not sure of cure! The Mic 1/8 IN socket is not chassis grounded on grounded to Mic Ground on Audio Hat. So PTT on mic panel jack is not chassis ground, and if you connect the Mic and PTT

Except that modules that have not been released yet are not part of the connection sheets. Ask though if you are interested. The big ones will be the Tuner, the 100W module, and the VHF-UHF

Ah ok that’s for the clarification. I had remembered that process working. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal

To be clear: the software is there to control the output attenuator. There was a bug when trying to use the menu to do so, but this does not affect any of the calibration routines.

ALL was fine until I tried SSB TX. PTT will not go into TX, CW keys up just fine. I went directly to 1/8 input socket and tried grounding PTT there and still no luck. Tim W4YN

Hi David:You might also want to join our site, too. (/g/SoftwareControlledHamRadio) There is a boatload of information there plus a lot of stuff in the Wiki and Files sections that

I can control output power. Am not near my T41 so can’t test voltages dave, n3ds

Ok so the software wasn’t there to adjust the TX attenuator. How the heck did Al calibrate the output power then? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ

When RX_BPF is LOW/FALSE/0, S21 between J23 and J18 (assuming receive is bridged to transmit in the TR switch) should be low, meaning less than -45 dB. That's what is shown in the plot on the
