Mike Don't think Bob ZL2CA has resubbbed to the list yet but he has a TS850 and would no doubt be able to shed some light on this. He has measured DDS errors at less than a few tens of mHz I think, b
It would be interesting to have the details of the frequency measuring setup for the stations measuring with the 1 Hz error. Is there a common factor? DaveB, ZL3FJ Hi Peter, I have carried out the sa
I ran Cons clicklock program for a couple of months monitoring JJY on 40kHz-works very well. Interesting to watch the phase plot come 'out of the noise' each evening and disappear each morning. With
Hi Nic- any action on the LF band front in VK yet? 73 Dave, ZL3FJ What design is your PA? 73's Nic McLean VK2KXN / VK5ZAT 1200W out and the rain is sizzling on the coil... silly boy...won't you ever
Pictures of Frank's LF setup are herehttp://homepages.ihug.co.nz/~tractorb/frank%20PE1RRF%20pix/ Well worth a look. That LF antenna tuning coil is very nice. Looks like it would be better spaced furt
Certainly Frank-send them direct and I'll see what I can do to make them available. 73 Dave, ZL3FJ Hi Dave, Is it ok that I send the pictures to your private e-mail adres? Now at this time I dont hav
Frank How about a picture of the ballon/corona ring -I think we all would like to see what it looks like. Someone here can no doubt post it where we can all access it? 73 Dave, ZL3FJ Hi, Thanks Micha
Has anyone done anything along the lines of the subject line using a mechanical switch/relay arrangement? I expect that any electronic method would add considerably to the capacitance from the probe
**SNIP By The Way : Are there any other counties out of the few have within their allocation to cover our 501 - 504 KHz or are we on our own on this one. I am happy to see OFCOM etc allowing this slo
I have a box of probably that many somewhere-but need to find it first! <g> 73 Dave, ZL3FJ Does anyone know of a reasonably cheap source of large Ferrite Rods for LF/MF up to a MHz or so? eg approx 0
John No problems on 182 kHz with 800 watts into a 50 by 25 foot loop and neighbours within 10-30 metres on all sides. I can't recall any interference issues over the last 15 years with any of the oth
Thanks for all the comments on this-Jay and the others. Those of you who have a protective relay in service in an E probe-have you any recommendations to make as regards the mechanical layout? Keepin
So just how stable are the resulting outputs using these things? Anyone looked at that yet? Its a given that you will need very good to excellent frequency stability once things go beyond the aural C
I've not found a s/mode wall wart yet that was adequately quiet, RF wise. Most are quite 'nasty'. Same goes for a lot of laptop AC adaptors/chargers, as well as quite a few mains driven battery charg
Is the Panasonic system capable of being operated from an external battery supply? A lot of the modern ones can use a backup battery but are not designed to operate from an external DC source. But if
Very interesting experiment, Jim. Did you try checking the coil output with it positioned alnogside one of the trees, as opposed to actually wrapped around it?(i.e. wrapped round an imaginary tree tr
Dave I have the service manual for the SPM-3 here in electronic form - BUT- I have not processed the scans etc yet so it's still rather large at about 140MB total for all files. It should be somewhat
