Dear Farhan and friends, Hi! A BITX for 144 would indeed be a very satisfying project but as Farhan has rightly noticed no SSB activity on 2 mts. My IC275 has hardly done any QSO in that mode. I

Hi Peter, It is a bit disappointing to me to find out that no one replies on your question. Of course the possibilities are discussed what all can be done with the x-tal, that a soldering iron can

hi, let me apologize for having turned a lurker on the the list. i was co-opted into becoming a wedding co-ordinator of sorts for three marriages in the family. the indian weddings are a long drawn

Dear Rahul, Thanks for your quick response. I had sent you another email after reading the vuqrp group as well. Today I found both the vuqrp and the bitx groups and was very impressed. I talked to

Hi all Have I missed something but what is an NP0 capacitor and where is it (or are they) in the circuit ???? Charles G4VSZ

Dear Jay, Sorry to hear abt your unsuccessful trips to the mkt. I dont think any one is making a BITX at Mumbai. While you are there I suggest giving a call to my good friend Charu VU2UPX. Ph:

Damn, its done it again. ( always the computer at fault :-( ) sorry for the multiple posts. Mike --

Thanks Indra for your $ which arrived here this morning from Indonesia. I'm sending this to the group in case anyone hasn't yet paid me for the component packs - I think you all have but due to

Hi, I am currently on business in Mumbai and wanted to interact with BITX builders in Mumbai. This project is interesting since all components are available in India and I happen to be in the

Hi Folks, I've just received my new Temp. Controlled Soldering Iron from Maplin UK. It is currently on special offer, and what an offer !. Previously sold for 29.99 its now on offer for 9.99. It has

Several builders are examining other bands with alternative intermediate frequencies. When doing this, it is vital to look for potential spurious transmitter outputs. Ashhar noted that this can

Hi Just a quick thought regarding improving or modifying your particular BITX20 transceiver: Since the BITX design includes a 10 MHz oscillator as the BFO, it would not take much circuitry to send

dear forum, as an interested reader of this forum, and beeing someone who's aiming to build a bitx in the near future I wonder if there are already people who have finished the building of this

Hi! The more I think more I am convinced that this is indeed a simple way experiment with modern techniques. If we plan to go SDR route along with downconversion then we find the critical Xtal

Arv I just had a quick look at this. With the current group settings, any member can create directories and any member can create files in any directory. What you cannot do is edit or delete an

Rahul VU3WJM That is the beauty of the BITX design. It has so much potential that it gets one to thinking about all the interesting possibilities. Here are some more "ideas" that relate to the

Hi! Arv, Baseband...... This is good thinking. I was wondering on a 2.5Mhz If for BITX and 10Mhz xtal clock for detection and rest thru SDR soft. Only a couple of more diodes to add (I Q

Wow !. Thanks Arv :-) vy 73 de G8NXD, Mike W --

Hans I think that either yourself or Farhan will have to build any "group writable directory", if it is even supported by Yahoo. In building my K7HKL directories in the Files and Photos sections I
