Re: Recycling monitors

My VFO uses just a simple 74LS04 inverter, and it's surprisingly stable even at 10MHz, after some warm-up time. Perfectly adequate for a CW QSO. The main problem with it is that I did not gear the tuning knob, so the tuning rate is very fast! By the way, speaking of recycling - that tuning capacitor came out of a 1970's radio tuner which I dismantled. I found it at the rubbish dump a year ago. I had a car full of garden waste which I was dumping there. I saw this thing on the ground next to the door where you pour the waste in. The strangest thing happened! All by itself, it just jumped off the ground and into the boot of my car! All I know about the Tweenies and Teletubbies is that in both cases, they wear ridiculous suits in bright colours, have silly names, and dance around singing funny songs. My daughter is the expert ;-) 73 Hans G0UPL -----Original Message-----
From: Ron [mailto:pa2rf@...] Sent: 11 February 2005 07:20 To: BITX20@... Subject: [BITX20] Re: Recycling monitors Good morning OM Nice 30m rx Hans! Similar to the dc rx i built, altough i used an old so41p (which are not produced anymore). And i have used to x-tals for the oscillator instead of a free vfo. Ordered them from Funk Amateur a magazin in Germany. The complete trscvr is in an old CD-player housing now. With a nice Aluminium plate on the front, it looks brand-new (Where did you buy that ...) Sometimes there is some broadcast breaktrough but not often. I discovered that around 11 o-clock in the morning and 4 o-clock in the afternoon i get the best results. Stations seems to be around the corner. I worked with 5 watt station from Poland which was awfully loud. If condx are there it is a great band. During evening the band seems dead last couple of weeks. I think G - PA is too short distance for 30m but we can try if you like. I only have 10,108 and 10,118 on cw available...OK, i asked my son about Tweenies. He said they are similar to the Tubbies and further refused to talk about it :-(( He is into Yu-kiyo, Spongebob Squarepants and The Karate Kid these days... bye ron --- In BITX20@..., Hans Summers <Hans.Summers@t...> wrote: transceiver for 30m. Nice job on the 30m rig, I hadn't seen that on your sitebefore, I think it is newer than when I previously visited. I have a 30mdirect conversion receiver see <> but it suffersfrom plenty of broadcast breakthrough. Nevertheless I had some nice QSO's on itget my station QRV again on 30m we can try a QSO! PA might be a little tooclose for 30m though, except under unusual band condx.1st April. Only problem is, she gets very angry when the programmefinishes and blames it on me. What does she want me to do? Telephone the BBC andask them to play it again? Ah well, guess I shouldn't have dismantled thevideo recorder ;-)> . < ure/ji bjabinaugural.html> Jab's 'Second Term'< ure/ji bjabinaugural.html> Jab's 'Second Term'< 6/D=gr oups/S=1705063108:HM/EXP=1108130267/A=2532114/R=2/SIG=12kg7r4ig/*http: //clk. atdmt.com/NFX/go/yhxxxnfx0020000014nfx/direct/01/&time=110804386715136 4> Service <> .
