Re: I find the Transmit audio is a bit muffled has anyone else found this?
Thanks to the group for this thread, I just installed a 15-60 pf trimmer at C103 and adjusted for crisp receive audio and the transmit audio sounds great now!
Hoping for some contacts tonight on the 9PM get together around 7.277!

Re: source for AD9850 DDS module for W8TEE TFT/VFO?
Doug,
I actually
received the "Right" AD98590 module pictured in the listing from these two Ebay
sellers:
?
http://www.ebay.com/itm/172381520736

On the

Re: BITX QSO Night, Sunday, May 28, 9pm Local Time, 7.277 MHz
My observation might be a confounding two cents, but here it goes. I don't hear the kilowatters other nights. We might be the QRMers stepping on their established nets or whatever. I think another night as well as other frequencies should be considered.
I plan to participate again tonight. de KG5KYJ, John, Oklahoma City.
I'll be working 7.178, 7.277, 7.285, as needed.?

Re: BITX QSO Night, Sunday, May 28, 9pm Local Time, 7.277 MHz
Just a reminder that the QSO night will happen this evening on 7277 in North America and 7177 elsewhere.? 9 pm local time.

here is a simpler way,? 1. change the band pass filter to 28 mhz. take the tap off the antenna end of band pass filter, modify the sktech to work on 28 mhz and you have the base of your transverter ready.
2. look around the vhf/uhf books and find stripline filter that makes a bandpass filter with just an etched FR4 board. no tuning really needed. now, add two 1N4148 as anti-parallel diodes, take an additional clock output of the raduino running at 202 MHz and use it as the LO (the anti-parallel mixer needs the vfo to be at half the LO frequency). you are on 70 cm!
3. to improve noise figure add a one dollar MAV-11 or MAR6, between the mixer and the band pass filter. Wow, now you are transmitting a full milliwatt
if this is all too cumbersome, just go and buy an RFM22B for three dollars. you don't know what that is? have you been living under a stone?

Good Idea...if I can remember it! I'm trying to limit the emails sent to the group. It should become less and less.

Jack, It might be easier for us to search for all the posts related to your board if we agree to suffix them the subject like with "w8tee vfo" or something. that way, the those how come in later will be able to search and read these posts sequentially.
just a suggestion, it will involve reposting the questions under a new subject line, but the categorization will be worth it.?
the other way is to add an easter egg '#w8tte-vfo' in the reply itself. those who search for this term will find these posts. it is a way to hashtag within the posts of this group.

Re: source for AD9850 DDS module for W8TEE TFT/VFO?
SainSmart has them, but pulled the old switcheroo on me. I ordered 25 of the Type II that I need and they were advertised at $12.73. I got them down to $12 for 25. They then informed me that the shipment was delayed. Later I got a shipment statement with their part number. I went to their site to compare the number with my order and discovered that the part number was for a Type I, which wasn't even on the page before. The Type II was also listed on the page, but for $23. I raised Holy Hell and they said they would "fix it". I don't know what that means yet, but will let you know what I've found out.
One of my User Group members (SoftwareControlHamRadio) is making a PCB that takes a Type I and fits it into the Type II mount configuration. After he reports back, I post his contact info here. He feels it will be under $2 for the adapter. We'll see.

Has anyone found a reliable source for the correct version of the AD9850 DDS module for Jack's TFT/VFO board?? I am dreading waiting a month for the slow boat only to find out I got the wrong one.

There seems to be some confusion about how U2, the SMD part, is oriented on the PCB. I've attached a photo that should clear that up.

Re: Baofeng microphone mod for BITX
DJ4MU, and All,?
While I didn¡¯t try too awful hard to figure out how to make my Baofeng work UN-modified, I was not having much luck, so having a handful of these on hand, I just opened one up, disconnected the speaker, cut traces, removed SMD devices and made sure the PTT and the MIC wiring and traces went only to the devices and indicated pins, while retaining only the shortest possible runs. ?I also made sure my jacks were mounted to plastic and not grounded to a metal chassis. ?I also drilled out the tiny hole in front of the mic element.?
I used two Radio Shack square panel jacks to plug mic plug into. ?If you turn the flat sides against each other that are 180 degrees away from the solder rings on the jacks, then the mic plug will slide into place perfectly.
So, while my mic is not interchangeable any more with my Baofeng HT, I sure don¡¯t care, as it fits my description of a junk box find @ under $5. And the jacks are part of my multi hundred part cleanup of multiple Radio Shacks. Below is my prototyping set up.

Despite the posted diagram i'm still not sure how to wire up the unmodified Baofeng mic to the Bitx. the speaker connections seem obvious, with ground on the sleeve of 2.5mm and other speaker connection to tip. the mic + connection seems fairly obvious too , on the ring of the 3.5mm. But where are the mic - and PTT wires from the Bitx connected, and do they all use the same ground? Which Bitx wire connects to the tip of the 3.5mm (v+) ?

What spec am I looking for regarding the display, have seen a red on a black background somewhere.
But do not really know anything about them.?
Must be 2 line as the menu, comes up on the lower line, and would rather just a plug in replacement.
On the search for hardware, seems to be a bit of a short supply, mainly knobs. Need a decent sized knob for the tuning control.
Just trying to work out the front panel layout, and either front or back may have a USB socket for updating the Raduino.

Re: doTuning() mod, utility, vanity
Bob:
There are several other options like the PIC32 based Fubarino Mini(32 Bit, 40 MHz, massive RAM & Flash).
And like you pointed out there is the 5v/3.3v issues. There are also pinout issues, delay loop timing, and more importantly library incompatibilities. Many "standard" Arduino libraries do direct Atmel register access that won't run on other architectures. There are hundreds of posts on the chipKIT Forum from folks having trouble using Arduino libraries on the PIC32 family of chipKIT boards. You can't assume it will work across processor architectures. Some library rewriting/porting may be required. As they say YMMV...
That said, with good Eagle-Fu you could layout your own 32 Bit "Raduino" on an architecture of your choice.

Re: BITX40 Microphone options
On the Yaesu speaker/mic I have, the MH-57, it looks like mic and PTT are on the same ring, third down from the top.
Will this not work with the BITX40?? Do PTT and mic need to be on different circuits?
