Dear forum, How do you select these xtals, I mean 2, 7, 8, 9 sort by "one leg to ground" or 1, 11, 2, 9 srt by "one leg to ground but via cap 33 pF" ? Thanks. Yours, Milarepa

the previous site http://farhan.net.co.nr has had too much traffic. now i have setup a new site with unlimited bandwidth at http://www.phonestack.com/farhan. the new writeup has an updated circuit

Hi people, havent been this excited about homebrew since I was a kid and built my first (totally illegal) valve CW TX - thank you Ashar, do you realise what you have started? Have done the VFO and

Just a quick introduction - I'm David G3RYP and am currently building the BITX20. My usual breadboard construction method : a sheet of wood onto which scraps of pcb are held by drawing pins -

Hi all My BITX20 is at an advanced stage of construction, but due to family commitments I won't have very much time to finish it off over the next few weeks. I used a modular construction style,

Hello fellow constructors! What a good idea Hans to set up this group! Just to say I am logging in and I am keen and excited to start building this brilliant bit of kit! All the best. Duncan G4DFV

guys, pete joins us on the group. he has details about substituting the tv baluns cores with FT-37 cores. he has also pointed out that the receiver gain is low. anybody else too who has experienced

Much as I would like to be able to take credit Duncan, unfortunately it wasn't my idea: I first heard it from Andrew VK3BFA on the rec.radio.amateur.homebrew newsgroup, and think even he was

What are members doing about component sources? Keytronics has 10MHz xtals at ?1.00 each (ten required) and the 2N3866 seems to be obsolete. Do others see any difficulties in sourcing

I'm confused about the 2N3866 - what's it for? I see no mention on the circuit diagram; the nice thing is that a variety of transistors will do in this design. Rapid Electronics

Dear All I looked at Farhans site and found http://www.phonestack.com/farhan/xcvr1.html In that he says:- Substitutions The BF195 transistors can be substituted with any other HF transistor

Dear All, I'm sorry I have confused the BITx20 with an earlier transceivers of Farhans which does use 2N3866. I'll have to lay low for a while. Dave M1DGS

Dave, that's another of Farhan's transceivers, NOT the BITX20, that's where the confusion arises. That transceiver us dual band and doesn't use the same bi-directional amplifier architecture. 72/3

If anyone has managed to buy anything from Keytronics I'd be interested. I was told after placing an order that he was too busy doing some plumbing! David

Hi! Friends! It is a pleasure to see a dedicated group for Farhan design. I did make the last transciever designed by OM Farhan and also enjoyed a long chat with him on LL abt the same. BTX is

we have om wes, w7zoi on the list. we all know him like an old friend from his books and articles. this is a remarkable moment. - farhan

Hi Pete, congratulations Pete - looks like you are the first! - did you use the PCB layout, or point to point. How about posting a few pictures for inspiration for the rest of the group. 73 de VK3BFA

HI all just an introduction as requested. Name Mark, QTH Derby - central England. Been looking for a QRP SSB project for a while and this looks just the job. Not started yet but will find some time

Hi Hans Happy to go for a 6.21 order from you! Regards, Mark G0MGX
