Hi Chris, what sort of 10 MHz OCXO do you have? The little canned industrial types (eg. http://www.kvg-gmbh.de/10.0.html?&L=3 STRG + Klicken, um Verknüpfung zu folgen http://www.kvg-gmbh.de/10.0.htm
Hi Chris, I think DFCW-600 or even 2400 is a good compromise between a constant carrier and some ID but 60 is probably to fast. Jim received you in less than 2 mHz if i remember correctly. QRSS60 is

Chris Some sort of ID is necessary. I arranged with OE5ODL to cut carrier for pos id. A continuous carrier needs regular cuts. QRS is preferable to DFCW as an ID tool. also regular feedback reporting
Hi Chris, I also think that a carrier interruption may be more suitable than DFCW, because it's easy to retain the carrier phase phase, such that a narrow FFT can integrate across the gaps. For this
Chris Manually cut the carrier, that is what ODL did and so I was absolutely sure it was him that I copied. For me QRS 600 and longer is too slow to wait for an ID. I shall be looking in QRS 60 - QRS
Chris, My system is on now (from 0900) and screenshots are being uploaded to https://dl.dropbox.com/u/15047843/xbm_grab.jpg. 73s Roger G3XBM On 10 February 2011 14:42, Chris Osborn <[email protected]
LF, I hope to be transmitting soon, at least by 10.00 Z Conditions are not ideal with light drizzle and freshening breeze but we'll give it a shot. The measured QRG is 8.976 642 kHz Thanks for all ef

Hi Chris, what sort of 10 MHz OCXO do you have? The little canned industrial types (eg. http://www.kvg-gmbh.de/10.0.html?&L=3 ) will stay within about a couple of ppb over hours, translating to some
Hi Chris, Very good luck. I'll be looking for you and hoping for success this time. An email direct and to this group saying when TX starts/ends would be helpful. Don't suppose you can send QRSS60 or
