Hi all I have been reading through the threads and have found that there are several Ferrite cores suggested fortunately I have them all ... FT 37 - 43 T 50 - 6 T 50 - 2 BUT can anyone sugest and

Mike Thanks for the great idea. Sub-circuit PCB layouts using Farhan's bi-directional amplifiers should find application in many other designs as well as the BITX series of transceivers. This

Hi Mike. Thanks for reply .Well i think it will be simple to post the files in the group's file section, if you didn't get it, ask for help.Someone in the list must know how to do it.Thanks also for

I've just uploaded to my website http://www.qsl.net/g8nxd/bitx/bidir_pcb.zip The files describing a small pcb for the bidirectional IF amp used in the BITX20 Tranciever.

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
