IIRC this is the place where I bought SMD parts some time ago.  They still have the day planner hole pattern.  I find that very convenient.  I put the resistors and caps in one binder and whenever I need one I just go leafing through it.

I wish someone would put together an assortment of, say, 40 common values, quantity 100 of each value and market it for some reasonable markup for resistors and caps. For the club build, I'd prefer 1206 since this is a huge step for some of the club members. 

BTW, today I just got 40 clear plastic 1.25"x0.75" cosmetic sample jars (eBay #332506418787). Tomorrow I'm going to Target and buy Velcro sticky tape "dots" and place one half on the bottom of the jar, and the other on a piece of plywood which hangs on the wall. Now if somebody has an assortment of 40 common values, they go into the jar and I'm ready to go. Each jar will have a small Avery label on it.

at

They are the ones who do the purple PCBs which look really great and
also pretty cheap, only a few dollars (around $9.50) for three 35mm x
35mm
boards with shipping included.

I am so pleased that the price for creating PCBs yourself is now this
low, up until now I have been carefully making my own by etching them
but
now I can get them in a few days if I need them fast or a couple of
weeks if
I don't mind waiting. There are so many different fabrication sites
there is
always going to be a great deal to be had if you shop around a bit,
the PCB
Shopper site I mentioned above is really great for this.

I used a separate power switch, that way I can use a normal volume pot with 1/4 inch shaft if I wish. Also means that if pot gets noisy, I only have to replace with another audio pot.

They are the ones who do the purple PCBs which look really great and
also pretty cheap, only a few dollars (around $9.50) for three 35mm x
35mm
boards with shipping included.

I am so pleased that the price for creating PCBs yourself is now this
low, up until now I have been carefully making my own by etching them
but
now I can get them in a few days if I need them fast or a couple of
weeks if
I don't mind waiting. There are so many different fabrication sites
there is
always going to be a great deal to be had if you shop around a bit,
the PCB
Shopper site I mentioned above is really great for this.

So noted... I'm gonna have to give them a go for the next revision of my uBitx top modifications... $50 for 10 PCBs vs $105 from DFrobot is a pretty significant price difference...

They are the ones who do the purple PCBs which look really great and
also pretty cheap, only a few dollars (around $9.50) for three 35mm x 35mm
boards with shipping included.

I am so pleased that the price for creating PCBs yourself is now this
low, up until now I have been carefully making my own by etching them but
now I can get them in a few days if I need them fast or a couple of weeks if
I don't mind waiting. There are so many different fabrication sites there is
always going to be a great deal to be had if you shop around a bit, the PCB
Shopper site I mentioned above is really great for this.

Re: Multi band Radiuno V2.0xz

DuWayne Schmidlkofer
 

You could us a 2 pole multi throw switch as a andswitch.  One pole switches in the appropriate relay for the LP/BP filter.  The other pole connects to A2 and each position on the switch connects to a point on a voltage divider from 5v to ground. Each time through the loop, look for a change in voltage.  If it changes use the map function to determine the band and switch the 
VFO frequency.

Re: Creating Gerber files for pcb construction

n5ib_2
 

I visited the EasyEDA site this morning and noticed they have changed the portal for submitting gerbers for fabrication. It now brings you to a JLCPCB page with a gerber viewer that is different from the previous one.

Previously I'd had some problems - the previous gerber viewer provided on the site did not properly display copper pours on the bottom layer, and did not recognize drawn circles or ellipses unless they were converted to polygons. Sufficiently confidence eroding to tread carefully.

This problem seems to have been corrected with this new portal.

I received a small order of boards from them yesterday.(checked with the old gerber viewer) Very simple layout but with all of the elements in place - top&bottom copper, masks, and silkscreens, with edited features in the mask, and V-cuts to separate individual boards. Fabrication was satisfactory in all respects. I was contacted with some questions and requests to verify that my somewhat "unusual" features were intentional and not errors. So it appears their checking is more than just perfunctory. I will probably send them another more complex and fine-featured layout soon.

Re: Oscilloscope for Beginners - A story

Robert D. Bowers
 

I remember the first digitizing scope I heard or read about - one made by Heathkit and sold many years ago (when they were still in business).  It had a 50mhz bandwidth and communicated by serial port.  I wanted one in the worst way... both for ham stuff and for my industrial electronics repair business (CNC/NC).  I never owned one (too expensive), but later acquired a 7000 series digitizer plug-in (with docs and spare for parts) to add to my good (analog) scope - sold as untested surplus and required repairs.  The digitizing stuff came in REALLY handy at times (I also owned a analog Tek 7900 series storage scope for several years - impressive bandwidth and it worked great, but big and heavy!)

I lost all of my equipment (plus radios, equipment, parts and manuals) in a fire, but since then lucked out and picked up a 500mhz digital and a 35mhz analog in recent years.  The thing is, if you have an idea of what you're going to 'look for' with the scope can guide you to the one you want to use - digitizing scopes can do things (like capture glitches) that are relatively difficult for analog scopes to get, but at the same time they have their limitations.  I'm not back to near what I was before the fire, but at least I can do some stuff...

At the time they were $299 new, I bid $260 on eBay.  What a deal, and you get 4 new probes!  No tax and just a little shipping.

There are tons of information out there on the DS1054Z.    Lots of reviews.  Only big complaints are too much on the screen and it is very small.  The encoders have small knobs, and you have to push just right or the encoder might move?  There is a hack out in the wild to change the options yourself, so you get 100 Mhz and special triggering functions, and deep memory.   You do it at your own risk.  You can find info on lots of sites.  I doubt if their newer models have this "feature"?

I just wish it was a little bigger.  I hope it stays working now that I am bragging about it!

I really hated my $65 PC connected scope mentioned to start this thread.  Hantek had NO support and no Firmware

updates.  I had to carry a big 600V 1uf cap to AC couple it.  The triggering options were very minimal.

Like you I really like Real Analog scopes, but their day is gone.

Anything moderately cheap is "parts only", refurbished you spend about
as much as you would for a new Rigol.

Unless you get a really good deal on one you know works,
I can't recommend an old used scope to the typical hobbyist.
Fixing those old scopes with all their custom parts can be non-trivial.

Re: Can uBITX be modified for AM Phone operation?

Dexter N Muir
 

In principle, TX is simple. Bypass the filter and feed the audio on top of DC (to unbalance the modulator). RX better by a small SW set: feed the converter from the IF and BFO (suitably offset ) and the audio back in to the vol. pot.

I tried very tediously to Calibrate it.

Re: The case of Two Raduinos

Jerry Gaffke
 

I'd guess it is a calibration issue, the BFO is at a different frequency on the different Raduinos,
either because the reference oscillator is different or (more likely) because the Raduino shipped with the uBitx
had a correct calibration value stored in EEPROM to compensate
.
Try moving the BFO around using the calibration routines. 
The frequency of the BFO relative to the passband of your crystal filter 
will determine how the audio sounds.

Ok you could do what I did and use a band switch. You can order a multi poll bandswitch and do it manually for the bandpass filtering and use external low pass filter for say 80 and 160m.

Band (filter) switching would require some IO pins to drive relays.
Unfortunately there's only one free IO pin left: pin A2 (previously used

With just one IO pin we could only switch between two bands.

Would it be feasible to add multi band options to the Raduino 2 software?
It would keep the same IF shift etc but have extra controls for band up /
down and to switch in the different BPFs / LPFs? It would also need to
reverse the BFO side for USB / LSB for bands above the IF I guess.

Any my advice would greatly appreciated!

Re: uBitx TX performance with frequency

Henning and all,

I am not sure the individual-chokes-method is a mistake: my understanding is that technique results in a substantial improvement in IMD.

Remember, every design decision is a tradeoff.

I guess that there are two design mistakes:

2. the input cpacitance of the FET´s do a big harm

Please have a look on the often cited WA2EBY amp: he uses the choke (T2) on the output and in addition he is using inductances from the gate (L1, L2) to the bias feeding resistor (27 ohms). To my understanding the inductor forms a parallel resonator with the input capacitance of the FET thereby flattening the frequency response.

In Part 2 of Mike Krossors article (fig 4) the "bad" frequency response of "normal" IRF510 amps is clearly shown, so it seems that L1 and L2 togehter wit the series inductance of the input balun are upgrading the performance.

Please have alook on the Philips (NXP) app note NCO8701. In this app note they are also using inductors in the input and even from the drain to the balun on the output. Design formulas are also given there.

I am not sure if the drivers are "good" enough for driving the high capacitive input of the IRF510.

I recently read an article (EDN) about the 2N2219 als vidoe amps, they do not perform very well, althoug I remember that this transistor (two in parallel) was used in a 2 m AM transmitter (german company Semcoset, MBS22?, about 1969, the year I got my ham radio license). A 2N3866 is preferred even for video amps in the 50 MHz range!

What about a BFG135 or similar for the driver? Or: RD00HS ????
