All Since the unusually good condx a couple of weeks ago the band has reverted back to normal. I have not heard Uncle Sams boys. since then and I dont suppose they have heard me. When condx on 500 ar
I received a dispatch from abroad that some UK stns are being heard in VE. There are some VE/W stns listening for G stn acty and will work xband 3533 and 7033 Kcs. A good time is aroundf midnight ie
Hi Ha-jo You went qrt too early and missed all the action. I had a QSO with VE1ZZ at 0117utc I was on 502.5 khz and VE1ZZ 3534 khz. Good copy in both directions. This past few days propagation has be

Hi all I always check 3533/7033 khz plus/minus qrm when active on 500 khz. This has been very rewarding with lots of real time reports from EU stns not active transmitting on 500. I likewise also lis

Hi Marco. Tnx for the call on 3533 khz and the successful QSO. Sorry you did not work GI4DPE earlier. I got into the shack around 10 pm so missed the earlier activity. I always listen on 3533/7033 kh

Hi all Tnx to all for the information, but some of the figures do not work out. How are the % figures measured. One simple method is to calculate the DC input PWR in watts (I x V) then using an RF cu
Try CW which is the norm on this band, lots of QSO'S within the UK and xband DX galore, at least as far as SV/YU and 9H1. Most UK stns active on CW are being heard in those places. All class A UK rad
