Re: It's all gone quiet on ATS V5

On farther testing, the compander AGC is a bust. It’s got two problems. One, I can’t get the attack time fast enough. It takes 3-4 cycles for it to respond and that causes a heck of thump before it kicks in. Which is part of problem 2, it wants to try and make the output level 2 V p-p, even the noise. Oh well, it seemed like a good idea at the time…

 

So, back to the drawing board.  Diode clipping followed by the band pass filter sounds good. Instead of back to back silicon diodes for clipping, like on the MTR and original ATS rigs, I’ll use Shottkey  which will start to clip at a lower level. But that level is a bit low to use directly, so it will be followed by a ‘386 amp with a trimmer resistor under the front panel to set the maximum volume. That way various levels of hearing and headphone sensitivities can be accommodated. I think that’s a reasonable compromise.

I know Steve doesn't "do" lists, but your (Scott) are absolutely right.  That first thread he started when he announced it is a sort of list of orders.  It would be nice if Steve used that to sell the first batch.  As I, and others have said, definitely in for me.

Hi Steve,
With so much anticipation for your new rig, I suspect there will be more demand than supply.  Will this be first-come-first serve?  This may be disappointing to a lot of people who miss the notice (I suspect within hours you'll have your quota).  If you plan on a limited one-time production, have you considered some form of lottery to pick the lucky recipients of this little gem?  Just a thought.

That finished rig looks amazing.  Your workmanship is excellent.  I'm looking forward to  owning this beauty.

Sascha,
It doesn't seem that it is that far off. The adjustment of the bias trimmer is very touchy. A very careful nudge should bring it up another 30 milliamps. As for the lack of modulation, that is something to trace down.
Congratulations on your progress! Yes, a wonderful rig! 73, Don

SB II #112 nearly done / searching the last building mistakes

Hi everybody,

Though it took nearly a year now, I am finally almost done with my  SBI kit. Thanks you Steven for this really great ( or better small ) highly portable and multifunctional tranceiver.  I will use it a lot.

I first had some problems receiving anyhing but a rattling noise, but noticed only shortly after that I had wrongly turned X7 around 90 degrees. No wonder  After changing this the  RX worked immediately and I was happy.

The transmitter still has a problem, which I will try to pin down with the voltage chart shortly.

With the bias poti turned fully Acc , the current is only 120m  during transmitting. If I adjust it , I can turn it up quickly, but that does not solve the problem. Somewhere 30 mA are missing, I could imagine in the driver stage or so. I will measure  power tomorrow, when I got more time - the MOD LED does not flicker either, whatever position the mod poti is

I hope I will have sorted it out soon - I will report in again:-)

No, because there are five connections needed. Reset, Serial in, Serial out, serial clock and ground.

 

A place to plug in a standard 10 pin ISP header is built onto the board, so connecting up a programmer is not a problem. You just need a programmer.

 

Steve KD1JV

 

I know it's a bit of a kludgy hack, but could you hook up the ISP pins on the ATMega328 to the 3.5mm jacks?  I'm not sure if those pins are otherwise occupied or if they could safely be shared, or maybe you could program it through the 3.5mm jacks and then cut a couple of traces.  Anyway, just a thought.

Cheers,

Because otherwise you’d need to program it. Which isn’t all that hard to do and many of you can, but for others it would require getting a programmer like the Olimex AVR-ISP-V2 or similar. And you need to be able to program the fuse bits.

Why is there a need to program the chip before soldering to the board?

Howdy Steve.

Haven’t been following this rig as closely as I should have so regret the following dumb question.

Will the new rig be single-band for, say, 40M?

Many thanks for any info.

Looks like another winner!!!

Here’s a few more pictures. I haven’t tested the RF deck yet. Yesterday I was focused on getting it built and doing the mechanical aspects to make sure it all fit in the tin. Which I’m happy to say it does.

Now I got to figure out how to program the processor without mounting to the board first. And start on the documentation – that’s the hard part.

I just got a new set of boards in yesterday and I’ll warm up the workroom and build one this afternoon. The front panel board came without the display window cut out. Must of accidently deleted the board outline for the window.
