Hi BITX'ers and fellow homebrewers
Apart from making snowmen and throwing snowballs with my son today? I experienced some promising results with the receiver chain in my BITX17. I?completed most of?the front-end part with the filter components and hooked up the rig to my (random length) 14 meter longwire antenna in the garden. Up till now I have spent a total of 6 euro's on the rig (only bought the 10 MHz x-tals brandnew, rest of the components comes from the junk-yard
). Anyway..during daytime I've been able to receive?ssb phone,?CW, RTTY and PSK31 signals.?Some signals were very strong. I was amazad about the clarity of the SSB voice signals. Also the simplicity of decoding the RTTY signals surprised me. The amount of PSK31 stations was a little bit dissapointing. But I've been spoilt today! The promising conclusion; small digimode signals which require a good freq. stability (appr. 5 Hz) ?can be decoded with
the BITX in combination with the proper decoding software. I used MixW2.1 for this purpose, but programs like digipan (psk31) or CWget (cw) should also be able to do the job as well. An overview of the results is given below.?The 17m band apparantly is a day-band with lots of opportunities and quite a range in modes. After 6:00 PM UTC I did only pick up some interfering broadcast stations; no more 17m signals. The band had closed!
Some things that need to be improved in the rig; (1) in my PSU the 7812 regulator got quite warm, probably due to an unwanted?hi-consumer (2) In 80% of the time the huff and puff circuitry took care of a good stable vfo signal (better than 5 Hz) ; 20% of the time the freq. slowly walks away from its main setting (medium-term drift of appr. 100 Hz). Improvement?required !?(3) an internal frequency counter would be great (4) I like the blue LEDs. Must be?fantastic to have it in the front as TX indicator. Does anybody know where to buy them for less than 3 euro's?? Conrad sells them for 6 euro's. No way !!
When these items have been fixed I am ready for the TX chain !
Anyway have a look at the results? and hop to the URL give at the ssb voice part in the rx results overview?to listen to one of the CQ's I heard today. ?
Best regards, have a?fb weekend and enjoy the radiohobby,
Ron
