No worries, just thought I'd take a shot at it! I, too,

have a 30 meter 1-Watter from Diz that's half-built, a
20 meter OHR 100A from Marshall that's half-built, a
Norcal 40A (Wilderness kit) to start, a qrp-tech 40A
that's built through Chuck's first phase, a QCX that
will be built when the Enclosure arrives from Hans (it was
handed off to the Turkish post office today!) and I will
definitely be ordering a QSX after the initial rush quiets
down, you know it's going to be a massive hit if the QCX
serves as any indicator!

Man, typing this all out tells me I need to get

slop bucket assembly

Michael Maiorana
 

Just a quick question for those more experienced than me. I'm finally getting to assemble my slop bucket kit. Reading through the instructions made most things clear, but I had a question. Is it better to place all SMD parts first, then use the hot-air rework station to "solder" all the parts down at once, or is it suggested to solder them in steps or sections as the parts are placed?

I've done a limited amount of SMD, but this is my first big SMD kit.

Thanks, and thanks Steve for a cool kit.

Mike,
I have done it both ways - all parts and sections (IC's, resistors, capacitors). Sections is much easier for me (less likely to bump the parts around). I use a skillet and hot air to melt the paste. When I do the backside, I suspend the PCB above the skillet with a couple pennies at each corner of the PCB. When doing the backside,  DO NOT TOUCH THE PCB UNTIL IT IS COMPLETELY COOLED! If you do, the parts on the other side are liable to fall off and/or move.
Good Luck!

Re: slop bucket assembly

When I built my ATS3B kit 10 years ago, I did it in sections. 8 or 10 parts at a time. My soldering station was the hot plate section on a coffee maker for pre-heating, followed by soldering with a hobby store embossing hot air gun. It was all together too easy to disturb SMD parts on their dabs of solder paste. 

Enjoy your adventure.

I prefer to do it all at once and be done with it. Plus I’m in a hurry 😊

 

If you do it in sections, it would be best to do the passive components first and finish with the semiconductors.

 

But once your set up to start placing paste and parts, it doesn’t take much longer to just do the whole side. Plus your less likely to loose parts. Unless you can leave everything set up and undisturbed until you get back to it. You probably already know to keep the cat out of the room…

Slop bucket trouble shooting

John KG9DK
 

I have my slop bucket 20 meter board populated, how ever there are some problems. 
With power applied I get the display to show the 160.0, at TP1 and TP2,  I get 9.00079Mhz and 23.1606Mhz.
At about 12.6v in current is 140ma, that is about 3x to much for receive if I read the specs right.
Notice Q3 is getting hot to the touch, not any good audio either.
In checking the diodes I found that,,,,
Schematic U9 pin12 to D9 to RIT control.
PCB U9 pin12 to D10 to CAL control
I think I remember reading that there were some discrepancies between the board and the schematic so I am assuming that this is one.
am now in search of some trouble shooting aids.  Has anyone created a resistance / voltage charts.  If so I would appreciate a copy will need all the help I can get.  Other suggestions are welcome too. thanks

Re: Slop bucket trouble shooting question

John KG9DK
 

More info.... discovered that what I took to be  a power on led was transmit led... that is bad news but explains the high current draw...maybe??  while measuring voltages on U1, micro I found some discrepancies in the schematic vs pc board overlay.  On the overlay it shows pin7 and 20 connected to the D5v, on the schematic it show pin 7 and 21 as being Vdd.  I also check the TXEN (pin23) and it measured 5v I assume that is high / turned on.  Also pin 27 and 28 were high.   Now I am wonder if I have the latest documentation??? What I have is dated "revised 3-3-18 schematic updated, 3-20-18 Q2 color code corrected.  I am going to read the instructions again to see if anything enlighten me....and go thru the post for the slop bucket.

I miss titled my 1st post, I titled it Slop bucket trouble shooting.  It should have been Slop bucket trouble shooting question.

Slop Bucket?

Hank Greeb
 

Have I missed out?  I deliberately avoided the first run of slop buckets because it was a short one (50 I believe) and I figured the "Experts" would want to sn*p them up.

I thought there'd be additional runs of them.  Did I miss out?  Or, is there another "run" in the works.  I'd like to get one of these just for the "fish" (halibut), since the name sounds interesting and the author usually produces rigs with GRRRR8 performance.

It was a short run, hope there will be more though.  I'd jump on another.

I did get one and it was a good build for someone that can solder in that 5351, small SMT.

Its a really nice radio, I do use it often or my FT817 or the Argonaut 505.  Has a decent RX
and good TX power.  Runs real well on battery power with a low drain receiver.

My only complaint is from W1 land it only gets across the pond stations. Some
day I hope to work someone local with it. ;)

Re: Slop bucket trouble shooting question

John KG9DK
 

update.... seems that I did not understand the correct position for the VOX jumper... I have found out that it should be open for normal operation.  By doing that the xmitter led went off, my current draw is now 50ma. and I am able to tune the display.  will continue to check out, calibrate and make an enclosure.

The Slop Bucket SSB rig wasn't an instant sell out like the CW rigs always were. So, I wonder if I doing another batch is worth the investment of time and money. 

I'm thinking maybe a 40M version this time? 

If I get close to 50 "yes, I'd definitely buy one", then I'll go ahead and start ordering parts. If not, well, guess we'll move on.

I would be interested in one.

I have no idea which band at this moment, though.  Almost prefer 30m.  Anyway we can choose at order or build time?

This is a SSB rig, so 30M isn’t in the mix. Although it does do CW and digital modes, so I suppose it could be.

 

The main problem is a 30M version would need another IF frequency. 9 MHz is too close to filter out. I can use 9 MHz for 20 and 40, so that will be the two options for the next batch.

 

Don’t know when I’ll have time to make up more of these, I guess once I hunker down for winter.

Why would you want an SSB rig on 30m?

I'd be interested in one. Not sure what you're planning on doing, but I like building these things, and I don't have a kit-based SSB rig except for the uBitX (which is dead and needs me to resurrect...need to put on my cleric hat for that one) and the K2 I built moons and moons ago. I'd welcome an SSB rig of whatever band.

My partner will chide me that we just got a KX3, but like I said I do like building these things.

Forget that KX3, it's so much more fun to use a rig you built, and especially if you can show of the burn marks from touching a circuit board you just reflow soldered with a heat gun :) 

I would put my name in the hat for the 40m version.

Nah, Karl, I already have keloid scars on two fingers and a thumb from picking up a soldering iron I didn't remember was plugged in...by the wrong end! I respect hot things far more these days!
