I will continue to run a beacon overnight for a few days. Mode is DFCW 60, Frequency is 136.3183 dash, 138.3180 dot. DX reports welcome. One complete callsign per hour on the hour. Mike, G3XDV ==
I have not seen a reference to it here, but 9kHz enthusiasts might like to read the fascinating RSGB book 'Radio Nature' by Renato Romero, IK1QFK. This covers the frequencies below 30kHz. Several 136
After many years of using QRSS, I have been spurred into modifying my DDS to give me DFCW capability for the first time. Would experienced DFCW operators please give me the benefit of their experienc
Stefan, Thanks for the advice. It looks like I have probably got it right. The DDS mod just moves the frequency up or down one step, which gives me 0.25Hz shift which is OK for QRSS30 or 60, or 2.5Hz
An excellent day's activity on 137kHz yesterday with 5 countries received, the furthest easterly station received here and a QSO with a new country. In the morining, OE5ODL and DJ6GT were received. D
It is interesting to read of M0BMU's use of a limiter to reduce the QRM/QRN levels at 9kHz. I have recently experimented with this sort of technique to improve my 137kHz QRSS reception. I have added
Warren is right to say that transatlantic QSOs on 137kHz have been rare but he underestimates the facts. There have been around ten two-way contacts between Eu and NA, all with VE1 or VO stations. Su
Last night's 'fire' seems to have been a false alarm - someone else burning something, so I will be testing again tonight. The plan is to transmit an 'X' on 137.7757kHz at QRSS120 at the start of eac
Well, it is possible but I can't confirm it. I think many LF operators have had small fires because of the very high voltages (especially on the old 73kHz band) which often make conventional insulat
Last night there were four countries active - SM, UA, DL and G. Thanks to those who provided reports and grabbers. I will be active again tonight from 1700 to 0900 UTC, transmitting 'X' on QRSS120, o
I shall be testing using QRSS120 this evening. The transmission will be an 'X' starting at each hour from 1700 with the last one at 2100 UTC. Frequency will be 137.7755kHz. A 6WPM CW ID will be at th
Scott, If this evening's tests are OK, I will look at extending the time (possibly tonight). I am wary of too much beaconing in this part of the band in case it QRMs those in Eu monitoring for NA sig
Test transmission stopped at about 2000UTC after my wife complained of a burning smell coming from the garden. Couldn't see any flames but it is best not to take any chances. Will check the loading c
I will be active tonight from 1700 to 0900 UTC, transmitting 'X' on QRSS120, once each hour starting on the hour (except the first transmission at 1710). ID will be in 6WPM CW at start and finish of
I shall be alternating between 136.3182kHz (Mon, Wed, Fri) and 137.7752kHz (Tue, Thu, Sat) this week. Mode is QRSS60, text is 'X''. Each transmission starts on the hour. Beacon on 136.3182 will be fr
I will be transmitting on 136.3182kHz tomorrow morning (20th) using QRSS120, and sending 'X' at 0600, 0700 and 0800UTC. I expect to send one or two test transmissions on that frequency this evening (
