Hello Laurens, So far T/A propagation has been about the worst I have experienced for years. However, since a week ago, I have daily reception of LT-305, Alert, CAN NU at 82 degrees north. Today I ha
Hello Laurens, Yes, location seems to be the most important factor. I am living 10 km from the coast and have e.g. a 2200 km unblocked sea path to Jan Mayen. Regarding Alert, it is just 4000 km away
Hello Graham or anybody else using OP8, Forgive my complete ignorance, but are my OP8 decodes uploaded like WSPR spots and if yes, where can I find them. 73, Roelof, PA0RDT
Hello Jan, The best I received Joe last night was -16 dB. The signal was audible in mode USB and a bandwidth of 2.4 kHz Though we live only 80 km apart as the crow flies, progagation can be very diff
Hello Alan, Thank you for the information. That implies at least two hops and the second reflection point in full daylight. However, at this time of the year "full daylight" is something different th
Hello Clemens, They might be very real, albeit on an other band.... It happened to me one day, when actually listening on 477 and the software still set for 137! 73, Roelof, PA0RDT
Hello Joe, I am running a PERSEUS overnight spectrum recording from 200 - 600 kHz each night. So, it is no problem to run OP8 on 477 kHz whilst these recordings are running. Looking at last night's r
Graham, Thanks for the info regarding immunity to static for OP8. I noticed last night, high background noise , and Joe's signal dropped at one point , that may of been a Ae change ? The Kyoto Dst dr
Hello Joe, Last night catches: 06:34 477 VO1NA de PA0RDT Op8 -32 dB F:8% in Middelburg 05:33 477 VO1NA de PA0RDT Op8 -33 dB F:8% in Middelburg 05:03 477 VO1NA de PA0RDT Op8 -27 dB F:3% in Middelburg
Hello Laurence, Yes, it is kind of weird. The Aurora Index was 8 today and dropped to 6 now. I still have a weak but steady signal from NDB LT on 305 kHz from Alert... 73, Roelof, PA0RDT
Hello Stefan, Congratulations with this excellent result! Regarding conditions, I noted at the time that northern propagation was good, whilst east-west or west-east propagation has been very poor! T
Hello Dennis, RTE 252khz is said to switch off soon. Due to much opposition of the Irish community in the UK, this has been postponed, so I have heard. The next scheduled date is January 19, 2015. As
Hello, Talking about RTE on 252 kHz, I just saw this message on the NDB list sent by Alan Gale. He won't object if I re-sent it here: (We will have to wait a bit longer for this one!) The RTÉ longwav
Hello Stefan, Excellent copy, albeit the signal is just 8 dB over the band noise in a 1000 Hz bandwidth. HSP does the rest! Roelof Bakker, PA0RDT JO11tm
Hello all, I wonder how many dB you will gain when the solar cycle be minimum in the years 2018 â 2019 ? HI. Someone mentioned here that there is a tipping point in regard to propagation at about 180
Hello Markus, The German Broadcasts are off and I have now an S8 signal from Romania on 153 khz. There is a weak carrier on 177 kHz and on 207 there is now a mixture of two stations. The strongest is
Hello Alan, I have been given your article "A possible way of Forecasting good Radio Propagation conditions on 136kHz" a good thought over. Generally speaking the Kyoto Dst figures are a good indicat
