W8TEE Pricing for Foreign Orders

Jack Purdum
 

There's been some confusion about foreign orders. The weight of the boards is such that I can send up to 4 boards for the same mailing cost. Therefore, in an effort to try and save you some cash on multiple boards, use this schedule of (US$) prices:

? ?Number of Boards ? ? ? ? ? ? ? ? ? ?Cost
? ? ? ?1 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? $15.00
? ? ? ?2 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? $22.50
? ? ? ?3 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? $30.00
? ? ? ?4 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? $37.50

Clearly, if you have friends who want a board, bundle the order together to save a few dollars.

W8TEE TFT /VFO BOARD Features?

 

Jack,

Thanks for the latest releases....

?
I have been going over the new manual ?and have the board nearly all done..
Just waiting for some chokes and some 78L08..
?
I have a few questions:
?
1. In the manual, on the display there is sw1 sw2 sw3 ? what is that?
?
2.How do I select USB /LSB? I use the digital modes such as jt 65
?
3. Is there a vfo option - more ?than one vfo? vfoA / vfoB etc or freq storeage so one can jump to saved locations.?
?
4. When putting the bitx in tx is there tune option ?(a carrier for the tuner tuneup)?

Re: BITX40 package size

 

The good news is that D7 blowing makes a whole lot more sense.
The bad new is that it blows if the power supply leads to the Bitx40 are reversed.
I'm having a hard time imagining any other reason for it to blow, except maybe a faulty diode to begin with.
I suppose it could have been stuffed backwards, though a quick power-up at hfsigs should have caught that.

Ok, I feel like an idiot now...

Re: BITX40 package size

 

L3 is fully isolated for DC by the three caps around it, so shorting L3 to C130A1 should not have done much.
Make sure both wires of L3 are still soldered to the board or receive will be deaf and transmit dumb.

Are you sure it was D6 (into Q6 collector) that was fried? ?
If so, this is all very puzzling.?
Any other hints as to what was happening when D6 blew?

D6 is only powered when the rig is transmitting, when it blew the TX rail likely had power on it for some reason.
If the IRF510 is only powered by 12v or so, it's probably fine even if it was transmitting into no load.
If it did blow, they are very cheap and easy to replace. ?The damage would be confined to the IRF510.

At any rate, so far so good.
I have no reason to think you did serious damage.

Probably also worth mentioning that there was no antenna/dummy load attached so maybe the L3/C130A1 short put the board into transmit but there was no load?

Hi Jack

I think a little more clarification on the international order cost would be helpful.

"4 boards go for the price of 1"

That suggests that 2 or 3 boards? could also go for the price of 1. If that is so, what would be the total price be for 2 boards ..... $15.00 for first +$7.50 for the second, $22.50 in total? $30.00 total for 3, $37.50 for 4?

By the way, my earlier offer to act as a VK/ZL group distributor, at cost, stands although I fully understand if you prefer to use the direct mail approach you have outlined..

Attached is an updated assembly manual for the TFT/VFO PCB I talked about at FDIM. Read the manual completely before building the board. I am also attaching the code for the TFT display and the VFO. There are two code files and there are directions for setting up those files for the Arduino IDE in the manual. Hopefully, the code is fairly easy to read. Some things I'm happy about; others I'm not. First, even without calibrating the AD9850, the frequency error is only 0.0000087% at 7MHz. After calibration (as explained in the manual), I cannot measure the error...if there is one. It looks dead-nuts on to me. Second, the keyer is simple, but works. I haven't told how to add the CW message switches yet, but most of you know how to do that. (I will be adding it to the manual, but wanted to get this out there ASAP.) Also, you can add paddles from your keyer and use the rig as a code practice oscillator right now. Dennis is finishing up the CW (and other) mods so I will have to change the code what that gets finished. And that's what I'm not happy about: The AGC, S meter, speech compressor, and CW mode is not implemented yet. You'll have that as soon as we get it done.

Note, the code is NOT a replacement for the work done by Allard. My PCB uses the Arduino MEGA 2560 Pro Mini and the Ad9850 (Type II) board which is vastly different that the Raduino board shipped with the standard BITX40.

I have more PCB's now and can begin shipping those. If you wanted multiple boards, but only got one before, please reorder. On foreign orders, I tried sending two orders as First Class mail in an envelop to get the costs down. One came back; hopefully the other one made it through. But, I'm not going to take the chance. All boards will go Parcel Post from now on. If you are in a foreign country, 4 boards go for the price of 1, so combine orders if you have a friend who wants one. Sorry guys, but foreign orders are $15, period. The additional postage averages about $11 and I have to fill out the export forms, which is a pain in the butt. Trust me, I'm not getting rich on you guys. US orders are still $7.50. Please note:

1. My paypal account is: ? econjack@... ? ? ? ? ? ? ? ?(please don't use any other account)
2. When you pay, there is a place where you can add a note: please write your shipping address in that note.

Re: Raduino V1.01 vs V1.14 Birdie at 7.200

 

As mentioned already please try v1.14.1
Please also make sure you're using the correct SI5351 library. It MUST be v2.01 (later versions are known for strong tuning clicks).

If it doesn't work for you you can always try earlier versions with less functionality.
All earlier releases are available at

For example v1.04 supports 10-turn tuning pot, but it doesn't have all the extra functions yet.

Right, taken another look at the board and the good news is that I didn't reverse the polarity! There are no obvious solder bridges or damaged tracks etc either which is good, however I did notice that one of the inductors (L3) was bent over and resting against the relay side of C130A1 (photo hopefully attached).

Probably also worth mentioning that there was no antenna/dummy load attached so maybe the L3/C130A1 short put the board into transmit but there was no load?

Would appreciate someone with more knowledge than me assessing how extensive the damage is likely to be?

Many thanks!

working now, I even attached the re-claimed S meter from an old Trio transceiver. Alls works well now, just have to make a

This bItx40 just keeps getting better, could take a while to get it into its case tho.....

there is only VFO, Cal. Button and Mic. connected in my Bitx40, I am only going to use it on LSB !
I have a lot of 7MHz CW Rigs from about 200mW to 750mW and there is a Regen set on workbench for CW ( 7.000 to 7.100 MHz ) in two version..... one for about 2 W and one for 30 W

Hmm, surprising.
The sketch provides more functions, but if they are not being used they can't generate extra noise or birdies.
Did you use v1.14 or v1.14.1? There was indeed a small bug in 1.14 which caused some ticking noise, and it was corrected in 1.14.1.
And have you tried different VFO drive levels to minimize the birdie?

Another thought: Perhaps the noise comes from the hardware modifications related to the sketch. Perhaps some extra noise is picked up by the wires to/from the function button, PTTsense, CW carriers ,etc?
