i finally got tracking on the replacement uP for my QCX40, looks like it will be here in a week or so.?? That shipment also includes a new QCX 20 to build after I get the QCX40 percolating.? Today I ordered a uBITX (via DHL) which may get here from India before the QCX20 makes it from NY.? Oh, also have a BaMaTec QCX cabinet due any day (should have bought 2.....).
I'm going to a very busy boy here ......"SOON"... group... "how soon?"? (great big grin). REAL SOON!!!
Meanwhile back on planet 10.... I'm digesting Jack P's excellent book on Arduino C and ordered a few Arduino's to play with.
I was pretty good with Fortran and DEC PDP-11 assembly language around 3 decades ago..? Hopefully it's like riding a bike and you never really forget how.

Jack / KZ5A,
It's more like riding a 'unicycle'!? I'm 'here' to save you from
hours of frustration!? I have a box of IBM cards (new) and a FORTRAN
coding ruler so you can find coding errors!? :)
Sorry, I couldn't resist!!? I programmed in FORTRAN (IV/VII/95) for
20 years!? USAF B-52G/H, F-15C/E flight simulators, and F-15S
maintenance simulator.

Ten statement Fortran plus Fortran IV for the IBM 360, featuring the WATFOR and WATFIV compilers.
1st ed. 1970 - my senior year in high school.
Hard to believe I was perusing that book nearly a half-century ago, wondering whether I might like to become a programmer.
Majored in girls instead...lots more fun !

Garry,
My coding wasn't nearly so
interesting.?
I was building one of the first
generation "Network Operations Centers" for the Telco? GTE of the
SW in the 80's.?? We primarily did remote monitoring and control
of the first gen of computer controlled Central Offices.
Pretty mundane but we wanted a lot more
out of these PDP-11 systems than the vendor wanted to supply, so I
was tasked with developing the desired "enhancements".?? It went
pretty well, I got some good training, and my stuff got adopted in
several other of the GTE Telcos.?
I never did any more commercial coding
but that work set my career path, I was the head technical weenie
for the NOC's for the first few gens and also got to design,
implement, and support the associated data networks (remember
X.25?)? Toward the end of my career I pulled a stupid move and
took a job as a NOC Director for Verizon Wireless, a job for which
I was not well suited due to my complete lack of social skills.? I
knew it was a dead end job for a number of other reasons but it
did get me a company paid relo back "home" to the DFW area and
gave me an oppurtunity to help advance some deserving
associates.?? After about 2 years to "Sopranos" wannabe's in New
Jersey that run Verizon closed my NOC, and pissed me off, so I
pulled the ring on my golden parachute and retired at 54.
These days I'm looking forward to
coming up to speed on Arduino C and seeing if I can gen up?
something useful and fun.?

Well, if my dad were still here ( W4MAI - sk 2006 ), he could tell you about how a single 8-bit accumulator would fill an entire equipment closet :0)
Many years ago, he worked for IBM? somewhere in upstate New York.
Eventually, he became a college professor, teaching a bunch of kids all about highs & lows and a whole lot more.
Anyone remember the Titus bros and the Bug Book series?...

Started on IBM 650 with direct machine instructions.? Then FORTRAN (no #), FORTRAN II on IBM 70954, 7044, PDPs 1,5,6,7,8,9,10, CDC6600, C on various microprocessors and Postscript (yes it''s a programming language).? Now content with Linux on IBM PC, plus R-Pi and Arduino.

I was lucky. There was an extension computing center in the basement of my dorm at Case (not CWRU then) in '67 with keypunches, and a window with a reader and a printer maned by a bored student. I could pad down there in my jammies at 2 a.m. to do my homework. As I recall I was an expert at duplicating a punched card just past the character I was trying to correct.
Then:
Hand soldered a mole of connections to build a Digital Group Z80 (bus but not S100) with 2K memory and computer controlled cassette tape drives. Programmed Z80 assembler
Commodore 64.? Programmed basic and 6502 assembler
Commodore Amiga: bitmapped graphics, multiwindow multitasking UNIX like OS. Programmed Fortran and FORTH, wrote a programming column for AMIGA Project magazine. The AMIGA had a modern file system, visual editor, symbolic debugger and optimizer for FORTRAN. At work I had an IBM dumb tube and a user hostile programming environment (JCL, no tools).? I wrote a transient coupled heat transfer and chemical reaction FEA code for process optimization at home and convected it to work. With the help of a plant db expert the optimizer was hidden under a simple interface for cure press operators. First deployed in '86, it's still in use in plants.
After that I convinced management to acquire some SUN workstations. That's when I started getting Jack's books that are still on my bookshelf and recently used.

Egads! In a couple of years from now the C Programming Guide will be 40 years old! Man, I'm so glad I haven't aged during those years...

Parts came in today, hoooray.?? I put the new uP in my DOA QCX 40 and it came up running.? Got thru the alignment, sort of OK but haven't got a distinct null on phase Lo.? R24, ends with up a minimum at full CCW.?? PO is abt 3 watts on 13.9V.?
I re-filtered it for ~600Hz and there may be some config parameter I missed.?? Anyway I'm listening to W1AW, sounds great.??
Couldn't use the keyer, almost impossible to make a correct character, so I put it in St Key mode and plugged in my trusty LogiKey K1 which works great.? No idea what the deal with the keyer is but I'll look into it later.
Also got my "practice Arduino" today and got stated on Jack P's book, got "blink" to work.WooHooo.

The key input is designed for a straight key or a paddle depending on what is selected in menu.? It does not work well with most keyers. If using a? paddle mode B seems to work best.
|
I just turned it off, set it for
straight key, and started using my usual shack keyer Logikey K1.
The internal keyer is not usable,
impossible to send coherent code.?? Not even close to being
usable.
I noticed one of the QRP kit sites has
a board to "fix" QCX keying and apparently I need one.
Same key works fine in my K1.

Try the Logitech again, with a mono plug.?

I got the internal keyer issue
resolved.?
Oddly enough, it seems the problem was
RF feedback related to running into a dummy load that was setting
too close to the rig.? Later, when I put the rig on my dipole the
problem went away.? The long cord on my key probably didn't help.
The QCX 40 seems to be working great
this AM, heard? Chinese and Marianas Is. DX.
Power out is abt 3W on 13.8V, probably
try 16V later but want to make some heat sinking upgrades first.?
I rough calibrated it by zeroing my SDR
on WWV and then calibrated the QCX against the SDR on 40.? It's
close enough to find spots where they should be.?
The radio seems to be working fine but
the R24 and R17 adjustments did not go right.?? Both adjustments
are at minimum with the pots full CCW.? I can't "hear" any trace
of the other side band by ear, but I'd feel better abt the
situation if I could get a null.
There was a recent thread related to
that issue I'll review. ? Also could be my selections of R's
trying hit a 500 Hz CF,? might re-do those for 600 hz and see if
that flys straighter.

I have seen RF on the paddle cable mess up other rigs even elecrafts. Using a shielded cable between the paddles and rig has worked.
