It reduces signal coupling, IE RF getting into the audio via the pot leads for example. On caution about the storage bins. The type of plastic they are commonly made with grows brittle with age and UV exposure. In normal use it takes some time for this to be a problem. But drilling holes in it will cause trouble sooner. I think one fan should do, if that is even necessary. Drawing off the radio¡¯s 12V supply shouldn¡¯t be a problem. You might want to check once it¡¯s all working to see if the fan causes in noise in transmit or receive. Try monitoring an ongoing QSO and disconnect / connect the fan to see if you can hear anything. You may want to run the fan off the transmit power contact on the relay. Ideally the fan would run a few seconds longer but it should work pretty well this way. |

Re: VFO Display - DDS

The Beta I refer to below is for the B40 rig, as I'm using an AD9850 and a TFT display. The AA code for the QRPGuys PCB is stable. Jack, W8TEE From: W6IDS <w6ids@...> To: [email protected] Sent: Wednesday, March 15, 2017 4:22 PM Subject: Re: [BITX20] VFO Display - DDS ?

it:

Was on vacation with no
internet...a promise to XYL.
I used the
MAR-3SM+ part for the antenna analyzer (AA) project because it's easier
to find. Right now, I'm using the same AA board for the display/VFO and it seems
to be doing well taking the VFO output via RG174 to Farhan's input pins. That
said, Farrukh is redesigning the board to bring almost all of the Arduino Mega
2560 Pro Mini pins out to header pins to make it easier to experiment with the
BITX40 (I'm lazy...B40). You can see pictures of the AA board that supports the
AD9850/Mega and the TFT display by looking at the assembly manual on QRPGuys.com
(look for the Antenna Analyzer menu option). The beta for the new board is being
tested and I would guess it will be three weeks before we have the "real" board
done. I have the code done so that it will autosize to a 2.4", 2.8", 3.5" and
3.95" mcufriend.com TFT displays. That should give some case flexibility.
?
Dennis Kidder (W6DQ and my co-author on the Arduino Projects book) is working
on a CW and AGC options for the B40. I'm working on the code for a capacitive
touch keyer (from the Projects book) which will do away with the need to
drag a paddle with you. Setting CW speed and other menu options as well as
tuning it done via a rotary encoder. The code provides for three CW messages to
be tied to 3 NO switches on the top of the case. Each switch is tied to one of
up to 50 canned messages (changeable at runtime). Press one of the switches and
that message is sent via CW. The currently-selected message is displayed at the
bottom of the display. It also monitors input voltage and has an S meter. (A
repost of the display is below.) I don't know what we'll charge for the board,
but it is a little bigger than the AA board to accommodate the different display
sizes. All I can say at this point is that it will be less than
$10.

Wiring up/assembly questions
richard kappler
All, I'm a computer geek, not an EE, so some of this is not obvious to me. 1.? The volume pot has 5 leads, 3 around the circumference and 2 out the back. Am I correct that the two out the back are for the on/off function? 2.? I've seen mentioned here and on a coupla youtube vids that one needs to wind ones wires. Is that all wires? And why do we do that? 3. I seem to recall reading in one of the recent posts that the instructions at HFsigs are incorrect for one of the wires, but darned if I can find the post. Can somebody shoot me a clue? 4. This is my first ever build, so I'm doing it in a plastic case, essentially storage bin with the slightly larger footprint as the shipping container but about 4 times as tall, to make it easier on me (no workshop at the moment) and to save a few shekels. There has been a lot of talk lately about heat issues, so I've ordered a heat sink for the VR on the raduino board, and concurrently ordered a pair of small (25mm iirc) fans for the case. I intend to use one to blow directly on the AMP heatsink, perhaps the other to exhaust air from the case. Any issue with just tapping off the 12V main for these? Obviously it would work voltage wise, but would it interfere with the radio? regards, Richard - W2KAP |

Bitx40 TX Pop
philip yates
I know its been discussed, but I am struggling to find a solution to the TX pop. Anyone ??? Taken me a while to get started as I had to start ordering components, so I could actually do some modding, ?couple of nice resistor, capacitor and electrolytic kits now on the shelf,? threw my old collection of parts away when we moved.

I remember mailing stuff from Canada to the US when US postage rate was $.24 and Canada was around $.45. When asked why rates were so high in Canada, our Canadian friends would tell us is was $.02 for delivery and $.43 for storage. Given that it often took 3-4 weeks, it may be true.

Re: Raduino
Search and then pick US only for US suppliers.? They usually charge more. But you will get them in a few day or week. Order 1 from them, 5 from China. I usually see a month on the ones that predict 2 months.? They don't want bad feedback because of shipping that they can't control? Also, I have used the "Mini Pro", it is cheaper, but you have to buy a serial programmer board.? They do not have the USB connector. Probably not worth it, as cheap as Nano has become? Mike, WA6ISP |
