Re: beacon receiver
Hi Mike, Paul et al Certainly the frequency of the 5068.8 rocks can be pulled easily. One thing to bear in mind: This receiver is a very basic design utilising two SA602's. The strong signal

MIke in the bfo circuit you could replace the trimmer cap with and inductor and move the bfo freq to the lower side of the "window" of the filter and rec upper side band ala Bitx20. the first mixer

Re: beacon receiver
I've seen this too. My thoughts were to use the 18.138MHz crystals from Genesis radio (http://www.genesisradio.com.au/order.html) for the LO, and an 8 MHz IF. Clayton VK1TKA

Re: beacon receiver
I don't know, using 5068.8kc rocks would end up with a 2.4kc center freq in the audio output. Hans, what do you think? Mike WE0H Paul D wrote:

I found a link to n3zi's site where he has a gen coverage rx kit suitable for 30m beacon op with dds or xtal control. I will have to check microprocessor xtals for combo that will cover 10.140.

Re: 30m beacon on the air
Hi Newt, Cool, glad the Grabber is of use. When your signal comes in here it is strong. I see it is gone right now but I'll watch as the night grows older...I will test and calibrate my Grabber daily

Re: 30m beacon on the air
I cut off a bit of the 'gimmick' cap and adjusted the signal to ride between 140077 and 140082 according to the WE0H grabber. Thanks Mike - I did my adjustment this evening using your grabber as

Re: 30m beacon on the air
Hans and group, Sorry about taking up so much bandwidth!! - I will lop off another bit of the trick cap this evening when I get home. I will target 5 Hz for my FSK CW. 72 (+30) Newt k0nwt

Re: 30m beacon on the air
Very hard to figure out the message with his signal being so wide. Looks like my Grabber is running fine. Calibration is within 1hz calibrated to 10mc WWV signal daily. Mike WE0H EN35hj hans
