Sam, Good copy in the hour or so before sunrise, almost O copy by me, and also by ZL2BBJ. The attached pic was captured at 1833 UTC. I'll send the second capture as a second email. 72, Bob ZL2CA JPEG
Sam, The attached pic is the one where sunrise causes cutoff (only part of the R was received). Nothing seen from other than RB6BN. 73, Bob ZL2CA JPEG image
Hi all, Andrew ZL2BBJ and myself both live in Wellington, so it is of interest to work out who has the longer path length to RN6BN. It is of course the short path. A detailed check for differential p
Sam RN6BN, See attached the first appearance on my setup. It shows the very narrow shift. It also shows the first element of the R has somehow been clipped. The good initial copy from 1600 UTC sugges
Sam RN6BN, Copy varied from O to M to T over your three hour transmission. Frequency shift was far less than previous tests, only 0.02 Hz shift. See attached the last N received at ZL sunrise (just b
Sam, OK on 30 second dot length. 73, Bob -- Original Message -- From: "Sam" <[email protected]> To: <[email protected]> Sent: Friday, April 16, 2004 8:15 PM Subject: LF: beacon RN6BN Hi Bob, Mike a
Sam, Yes! 16-19 UTC Ah well, last night was probably the worst for DX propagation to ZL since the tests have been run, but still encouraging as I have yet to find I receive nothing at all from RN6BN.
Sam RN6BN, Hello Mike and Bob! Thank you very much for nice LF DX experiment. I have no right to hold frequency 137700 for beacon. I hope to hear your signals by this summer. 73 and DX! OK, and thank
John, I was checking on your frequency from 0930 but nothing received. Mike, end? It ended at 1000 UTC. Concentrate on VO1NA -- he has many dB over me. My EU receptions have been marginal, and there
Dick and Alan, I agree with comments from Alan, it does seem your core is either lower permability material, or there is still some unintended "air gap" (I have heard of gaps being set by glass beads
Dick, well I rewound the ouput transformer. Again I have problems, and when checking the signal on a spectrum analyzer I found that it is peaking on the second harmonic. So it transmits the main sign
Dick, I will put it to rest now......hope to have more luck in the coming weeks. 73 Dick, pa4vhf Just a thought, how about considering another call sign, as you obviously want a PA for LF ;-) 73, Bob
Joe, I've had a look for your beacon since 11 May, and also one previous occasion, but got nil results so far. The path to ZL has around 2 hours of darkness, starting from our sunset and ending with
Joe, I suggest you leave the schedule as published for the time being. Testing with QRSS30 is more realistic if the path is a contender for trying a two-way QSO. .... With winter approaching you, per
Hi all, We have changed the booking for the next Quartz Hill LF activity night, from Saturday 19 June to Saturday 26 June. We are developing a mixed programme involving: - DFCW120 beaconing most of t
Hi all, I've been experimenting with high stability crystal oscillators for methods of fine tuning by external electronic means. Varicap diodes are nonlinear for voltage and temperature, so I was wan
Dick PA0SE and others, An interesting contribution. My pushpull bipolar QRO PA can run to near squarewave performance, and I have successfully used an inductor input low pass filter for many years. T
Laurie G3AQC, I'm pleased to hear that you have made use of the idea. My original objective was to be able to readily adjust the frequency of a calibration grade oscillator, for which fractional ppm
Hi all, The Quartz Hill ZL6QH club station will be activated on LF this coming Saturday night. The usual 137.7890/137.7886 kHz DFCW120 QQQQQ... beacon will run from before ZL sunset till after ZL sun
