That almost sounds like the keyer is on. Jack, W8TEE

Oliver, here's a recording of my T41 on 17m being driven by a carrier from a signal generator. Roger G8JWT

The BOM for the LPF Filter board lists all of the caps as 200V but the schematic shows 100V. The 200V and higher caps are almost non existent on Mouser or DigiKey and the few values there are $1.00+

Al I noticed that the Hilbert filter coefficients in v66-9 don't exhibit the same structure as in v50 where the negative 45 phase shift coefficients are just the reverse order of the positive 45 phase

V12? I'd check U8 on the LPF control card. It got fried on mine, and it caused transmit oscillation on the higher bands. - Jerry, KF6VB

John, We are developing a new website highlighting te T41. We would like to include some user implementations, including yours. If that is OK, please send me a photo and brief writeup about your

Jerry, We are developing a new website featuring the T41. There will be a page highlighting User rigs. Would you possible send me a pic of the T41 and a short blurb about your implementation to

I forgot to mention that the $8 shipping offer is for the US only. Outside the US, international shipping applies, and cost depends on the location. Al

Mornin' Oliver: Sounds like a terrific plans and just confirms that Al and I picked the right people to take over the reins. Jack, W8TEE

I don't hear any audio artifacts on 17m on my radio and can't make those that I do hear on 15m go away by turning the radio off then on again. Can you record a short audio or video clip of the

software is version 66.9. Only RF board with RX component installed No BPF or LPF board? installed No SHUTDOWN component installed I can receive stations via RX. Turn radio on, set to band 40 No

Sorry, forgot to add that the software is version 66.9.

1) Turn radio on, set band to 20m 2) Turn radio off 3) Turn radio on, note no audio pumping 4) Change band to 17m, note audio pumping starts 5) Change band to 15m, note audio pumping 6) Change band in

Awesome work Oliver!

Oliver, Based on my 30+ years as an embedded firmware engineer, I think you're on the correct path! The path is somewhat slower up front, but will prove to be faster overall because debug will be

Update time! I've been working steadily on the code changes for the last month. I've taken this as an opportunity to learn more about test-driven development and the concept of writing unit tests for

Can you please give an exact sequence of steps to reproduce this error, starting with a radio that is turned off. I think I can reconstruct it from your description, but want to be sure. Please also

This is from the manual on the one with SA functions ①The amplitude gain scale value of the output signal relative to the input signal, which is linearly distributed. ②The amplitude gain curve of
