Recently I came to the digital modes (again) on 6m, after I had seen in DX cluster entries, that activity had increased significantly. Here is something on my impressions.

Here is the source for the latest experimental version of WSJT-X (1.7.0-devel-alpha):

14 August 2016 Was out of the house and when I returned, I saw, that I had almost missed a good opening to US. I let the JT65A machine going and it received VA2SS (FN45) and WU1ITU (FN65). Great.
12 August 2016 Heard I, SV and worked EA and EI9E via meteorscatter.
11 August 2016 No Es. Made some testing with G and LA using the new WSJT modes like QRA64A.
10 August 2016 Some EA, I, EI, and the daily SV9 were heard. Worked EA1. Not much of Es.
9 August 2016 Received SV, YO, I, F, G ... Worked HB9, DL, EA, EI9E (IO44), CU2ZG (HM77) and S01WS (IL46) finally :-) I played with the different WSJT (JT6M, JT65a, JT9Hfast) modes a bit.
8 August 2016 Heard SV, EA, EI, CT via Es and worked SM6CMU/2 (JP85co) via Meteorscatter. The US opening in the evening just did not reach me.
7 August 2016 Early I worked several UT and later, when the band opened more, I got YU, EM2, F and 4X4DZ (KM72). Heard were F, S5, HA, LA, SV, 5A, G, GM, GI, EA, E7, K1TOL and more.
6 August 2016 Band was dead and came alive in the afternoon. Heard were SV9, SV, F, UT and TF and more.
5 August 2016 Big opening all day, but did not have all that time. Many countries were heard with best of all S01WS, whom I could not get worked. But I got some F, G, UB7 and others in CW.
4 August 2016 A good Es opening happened in late afternoon. I worked SV9, F, SV, DL, IT9, I, Z3, IS0 in JT, SSB and CW. Heard were 4X, LZ, YO, UT, G, GW, EI, LA, SM and more. Some weak aurora signals appeared as well.
3 August 2016 Only one F was heard with CQ.
2 August 2016 Lots of activity in CW. Heard F, EA, CT, CN, EI, GW ... Almost the same countries in JT65. No QSOs
1 August 2016 Came home late. Heard SV9, SV3, EA, EA8, OH, G, EI and more in CW and JT65. Only short and spotty openings.

144 MHz
4 August 2016 Aurora heard, but transceiver has a defect.

30/31 July 2016 I ran JT65 in listening mode. Only some DL, OZ and PA via tropo.
29 July 2016 Listening only. Heard SV, I8 and EA in CW.
28 July 2016 Not much on the band. In a mixture of probably Es and Iono propagation I worked EI.
27 July 2016 Good opening with many stations. Worked EA1,3,5 and CT in CW mode. In JT65 I read I8, SV9 and EI.
26 July 2016 Heard stations from I, EA and England in CW and JT65.
25 July 2016 No contact but I heard G on backscatter, EA5, I, SV, SV9.
24 July 2016 The Sporadic E season seems to slow down now. Less signals are heard. Worked OH2 in CW, shortly heard CT beacons.
23 July 2016 JT65 contacts primarily via tropo up to 700km. SV, EA, F and 4X were read in JT65.
22 July 2016 A few SporadicE signals heard, no QSO.
8..21 July 2016 ... Hiking in Austria ... ;-)
7 July 2016 Was on all afternoon, but not a single bit heard.
6 July 2016 Had JT65a running on RX. Around 15 UT I received NA6L (DM12) with CQ throughout several periods. First thought it might be a fake. I contacted him, and he has definitely been active CQing at that time. Nothing else was heard by me and others at that time in that direction. Surprise, surprise.
3 .. 5 July 2016 Only short openings. Nothing worked.
2 July 2016 Got JW7QIA (JQ68) in a late night opening.
1 July 2016 Switched on before I left home at 04:30UT and there was already one Ukraine CQing. But by returning in the afternoon, band was dead.

Days Off. So I am back from a hiking trip in Austria. Some wonderful days we spent in the Alps in St Martin / Lofer. Only the first day weather was good enough to climb up to a summit. Then a very severe storm destroyed some hiking trails and we preferred to walk through the woods. Our guides were well prepared and all of the group (18 persons) were in a good mood.

30 June 2016 What a day: Heard/Read OH, EI, EA, SM2, G, UR, GM, LA, OZ, I, S5, F. But then suddenly the band opened to West Coast USA and I worked K7CW (CN87lj) and heard N7NW (CN87). Having discovered as first operator that such a path is possible in year 2001 (see First ever West Coast in 2001), I am finally happy that I could work West Coast 16 years later. During that period European backscatter signals were extremely strong.
29 June 2016 F and EA worked in the evening. Read W3CP (EM74) in JT65 with CQ several times, when there was no opening to the west at all recorded. I contacted him and he confirmed having been active at that time.
28 June 2016 USA was worked from PA, but I heard nothing. Later I worked 15 stations in G, GI & GM.
27 June 2016 Some listening in JT65 mode.
22..26 June 2016 Was away for some days...
21 June 2016 Was on short only and worked SK0TM (JO86) via tropo and strong (JT65a).
20 June 2016 Many stations heard - best UN3M in JT mode. Worked a few in JT65A.
18 June 2016 First time listening JT65A for DX and immediately copied JE6AZU (PM51) with CQ in four periods. Not one else except some UA video signals was heard.
17 June 2016 Worked Ukraine and A92GE (LL56)
16 June 2016 Worked EA7 on Es. Got LA/DK2BJ (JP42) on Meteorscatter.
14 June 2016 Band totally dead
13 June 2016 What a day on 6m: USA wide open! Came home a little late but I worked: W2SM, K1WHS, K1ZZ, K4PI (EM73), W3UR, K2MUB, W3EP, W3JO, K3WW, K1RO, K2DG (EM12 ODX 8103km), KA1R, KA1W, W1FV, KSIX and KD5M (EM60). Hrd : NN4X (EL98), KA2JA, NT2X, VE1PZ, W3CMP, N6RW (DM34 !) and KC2TX (DM42 when 1st time trying to listen Es in JT65a). I felt, I was sitting right on the edge of the propagation. Others with a similar antenna just a few km west copied a lot more. My takeoff direction US is very good. The band went up and down for more than 3 hours.
Although I recorded everything I have some incomplete callsigns I even cannot figure out from the recording: a VE3, N8, N9 and K5.
European backscatter signals were weak this time compared to similar openings in the past years.
12 June 2016 Good opening. Hrd S01WS but too weak for QSO; EJ7NET (IO55) loud, but RX "kaputt?". Worked EA8CQS (IL18) and some G, GM, GW, EI, F and EA5
11 June 2016 Heard many form the South-East
10 June 2016 Many stations heard. Worked only YO and RK6
7 June 2016 Open to south-east; worked S5 and Z3.
5 June 2016 Short time on and got OH1.
2 June 2016 Heard TY2AC, but he never became strong enough. JT1CO was only weak and worked over my head into PA.
1 June 2016 Only some listening. A big bunch of I stations on the band

144 MHz
29 June 2016 Listened during opening and heard one weak station, probably CT1HZE. (My 2m TRX shows strange behaviour - it is old.)
10 June 2016 Only very weak signals during SporadicE Opening

Wow, what a thrill. The whole weekend (10 .. 12 June) we were busy recording our first CD in the recording studio. No, we are still far from being ready, but the main stuff is recorded and sounds already brilliant. On sunday evening we were exhausted but happy. Next steps will be intensely listening into the "takes" and adding tracks that are still missing. A booklet has to be designed and printed, photos have to be taken and, and and ...

Nothing special yet. There was a good aurora and I worked a few stations on 2m. On 40m I ran WSPR for 2 days in January, but for some unknown reason my computer rebooted several times which stopped the program. Some humming was discovered on the WSPR signal and I have not found the source of it so far. I did not change a thing, but somewhere it is different to before.
A strong storm broke the rope of the 40m dipole, but this is already repaired.

16 February 2016 Some Aurora going on in the afternoon. Worked SM5, LA and ES.

Another busy time ...
144 MHz
14 December 2015 A good Aurora. Stations heard down to Southern Germany.
25 October 2015 The reflection Zone has shifted and SP9, OK and OM were heard. Also some SM4 and SM5 were worked.
24 October 2015 Big tropo opening to Southern France and Northern Spain. Some EA1, EA2 and F were worked at S9 level. Absolutely phantastic.
08 October 2015 Another Aurora. SK4MPI beacon was strong but only few stations were heard.
07 October 2015 Good Aurora opening with strong signals.
03 October 2015 This unbelievable opening continued and the tropo Zone had moved east. This morning UA3WM (KO84) was worked with a strong Signal. Later band opened into SM4 and OH6. Then all over sudden it was over.
02 October 2015 The band was already wide open in the afternoon and it became better from minute to minute. Scotland was in at very high level very early. I worked stations from GM, G, GI, GD, GW and EI4DQ from IO51. Then it opened to the east as well and I worked SP, EU, YL, LY and UA3LID. And I heard both UA3 and G working over 2300km. I could make over 75 DX contacts over more than 700 km.
01 October 2015 A very good Tropo opening; I worked LY, YL, SM1, GI, GM and G. Some Aurora going on as well, only heard SM4IVE strong. It was visible as well.
20 September 2015 Worked SM4IVE via Aurora, LA and GM heard
9 September 2015 Low activity on 2m and heard LA and SM.
7 September 2015 Strong Aurora signals heard on 2m in the evening; I preferred to go outside and to observe the stunning Aurora. (IMAGES HERE)
