No SSB output

 

I have output in CW mode, but 0 in SSB.
Even doing TX IQ with 750hz tone or 2 tone TX 0 output.
FW is the 66.9?

Re: The T41 from 4SQRP and V11 boards.

 

Bill

Thanks for the long list of specs of the T41-V12.

I suppose that Andy G8HCK passed on my inquiry to him for a couple of V10/V11 QSE PCBs and you may be wondering why I¡¯m looking for such old technology. ?I¡¯ve been using my original V10 QSE board so much for hardware development that it is starting to fall apart with all the cut traces, solder jumpers and extra mounting holes.?? Fortunately, it still works in its original form.

For my purposes, the V12 RF boards are too dense for much hardware experimentation, particularly with 4 layer boards.?? I feel that they don¡¯t encourage the original ¡°EP¡± concept that Jack and Al first promoted.? I see the V12 concept as almost a pre-production prototype for a commercial radio with very tight specs.? I really admire the way that your team are striving to make it all work and I wish you all every success.

My T41 interests now lie in the direction which Greg KF5N is taking both for hardware and software development.? Of course it is a positive sign of an on-going healthy project like the T41-EP that it can and does evolve in several directions and long may that continue !

Re: Trying to build a AM Demod so I can see my CW signal

 

Thank you,? yep I want the envelope.?? Appreciate the fast answer!!
Re: Trying to build a AM Demod so I can see my CW signal

 

¿ªÔÆÌåÓý

You don¡¯t actually need a demodulator to see your CW signal on your scope¡­ you just need a scope that is capable of displaying the fundamental frequency of the transmission¡­ so any oscilloscope capable of displaying a signal up to 30(-50 )MHz will cover the entire range of the radio up to 10(-6)M inclusive.

?

You will need the demodulator if you wish to see the audio envelope of an AM signal.

?

BTW there are lots of good replacements for 1N34 (germanium) diodes¡­ 1N270, BAT46, 1N5711, etc.? The BAT46 is bar far the closest to a substitute and is currently available from Digikey and Mouser.

Noob trying to learn here:

It looks like I need to build a demodulater to view my CW signal with my O-Scope.?? (I found a circuit that I can build,? but it calls for 1n34A diodes.? What would be a good substitute?? I was thinking maybe a BAT46?? I'm hoping to use this on a QRP rig.

Any assistance will be greatly appreciated.

The Wiki needs a good scrubbing.? There is more obsolete stuff in there.? I fixed only one of the most serious problems.

Well... Apparently it didn't work as well as I thought it would... because you didn't know it was there in all directories... I guess I could say something about that in the wiki...

Re: Encoder question

 

Thank you, Oliver.
Re: Encoder question

 

There's a flag in the Config.h file that sets the steps for the encoder. I think that you need to comment it out if you're using the 4SQRP encoders. This line:
https://github.com/KI3P/SDTVer066-9/blob/d6351b5d936f2514e001ad4b337e39e10358ed75/SDTVer066-9/Config.h#L49

V66.9. I'm using the encoders from my 4SQRP kit in my V12 but it skips a lot of counts unless I turn the knobs slow. Do I have a hardware problem or a software problem?
Attenuator problem

 

V66.9, V12.6 RF board: In the 'RF in atten' sub-menu I get the proper 3.3v outputs on pins 21-26 on U21, but 'RF out atten' doesn't show any outputs on pins 1-6. I'm missing something simple, right?
Re: The T41 from 4SQRP and V11 boards.

 

¿ªÔÆÌåÓý

Well Harry¡­ here is a list of the differences between the V10/V11 series RF boards and the V12 RF board.? Just for reference:

?

?

1. Functions of the QSE and QSD combined into one board for synergy.

2. Si5351 LO is on the RF board to keep RF lines short.

3. Quadrature LOs are generated in the si5351 directly allowing much greater frequency span of base-level transceiver, now covers 600KHz-150MHz+.

4. Improved anti-aliasing filters using reformed filters and ultra-low noise Op Amps (AD8599 and OPA2209)

5. TX to RX Feedback line to facilitate auto-calibration.

6. New MMIC RF front-end gives flat gain over entire receive range and better than 0.5uV sensitivity.

7. Ultra-wide band impedance matching RX Input transformer facilitates isolation and static drain. ?

8. New high speed CW key-shaping circuitry for perfect keying.

9. Optional 32 dB in half steps RF gain control on front end (PE4302).

10. Optional TCXO for less than 0.1ppm frequency drift.

11. Optional precision-adjustable RF power output from exciter in 0.5 dB increments (PE4302, 32 power steps from for 1mW to 1mW)

12. Compatible with V011 hardware (but requires V012 Main board).

13. 4-layer board for reduced RF cross-talk and IMD.

14. Built only what you want/ need concept.

15. Same size as V10/V11/V12 Main board.

16. Single 12V connection. Onboard voltage regulators just for RF board. Distributed power model.

17. Works with either V10/V011 LPF and PA boards, or with enhanced V12 LPF and K9HZ boards.

18.? Optionally add a second RF board for second RX (great for DXers).

?

?

I may have a few V11 boards left¡­ I¡¯ll have to look.? If not, the Gerbers are out on my GITHUB for those who must have them.

I was interested to read Neville's comments re /g/SoftwareControlledHamRadio/message/33358

?

I haven't used T41/V12 boards at all but, looking at the circuits, the V12 RX circuits seem almost identical to the V10/11 in every way that matters .? My experience of the V10 RX performance is very positive, similar to Neville's.? The main? changes I have made and experiments I have tried relate to the TX side of my T41/V10 rather than the RX,? ?I've (successfully) tried some of Greg's hardware mods by hacking my V10 QSE board which now has lots of cut tracks and extra solder links on it !

?

I also use Greg's excellent T41EEE software.and have replaced the original T41 V10 PA by the K9HZ PA.

?

By the way, I think Neville did his own thing building his T41 rather than building a 4SQRP kit.

?

For me, T41 EP V10/V11 has been and remains a great project.

?

Thanks.

Re: Need Solution

 

I am a happy camper I am. Install new teensy, need a new audio hat, and I have a video display. As soon as the audio board come I will test the RF board along with the main board.? Will be working on the filter board. As of now my problem seems to be solved.
