Well, I am running around 400mW ERP (as stated on my Opera beacon) from a transmitter with 800W RF output giving 3,2A into an inverted-L 14m high with 5x14m parallel top wires. Antenna efficiency (as
Sorry for the off-topic post but I know there is a wide range of knowledge in this group. I am looking for information on amateur radio apps for mobile phones and/or tablets. The apps must be used fo
Very likely a false decode. The clue is the two question marks. In my experience, almost every decode with question marks is false, and there are very few cases where these particular decodes are use
Excellent signal from SAQ, 17.2kHz, at 1130-1210UTC. Key down was 30dB above noise, space wave also several dB above noise. My equipment far from optimum, Afedri SDR (specified down to 100kHz!), LPF
Stefan, there also appear to be some more Alpha frequencies in use occasionally this afternoon on approximately 12.50 (F6) and 12.70kHz (Fx) (single transmitter seen here). These are in addition to t
I shall be active for 24 hours on next Sunday's Activity Day, announced by Dave, G3YXM. All my operation will be on the 136kHz band. If you have not tried the band yet, now is the time to see what yo
There is one more 136kHz activity to those I have already announced. I will be monitoring 137.777kHz plus or minus 7Hz from 2200UTC Saturday 8 Aug to about 0800UTC on Sunday 9 Aug for QRSS60. Mike, G
I am active on CW this morning on 136.8kHz (too much QRM on proposed frequency of 136.5). Already worked G3YXM who also received me on his remote rx in GM. Any takers for this rare opportunity? Liste
I was active on receive and transmit from 2200 Saturday 8th to 0700 Monday 10th (not always awake, of course) on the 136kHz band. Unfortunately, bad QRN in mainland Europe killed most activity during
Graham, night time conditions involve single and double-hop sky wave which can be very selective. Stations only a few kilometres apart can experience completely different results. Anyway, nice to see
I agree with others on this. I get "do you know these friends" messages from Facebook at least once a week from signing up several years ago. I have never sent a single message to Facebook apart from
Marcin, My experience is that a few earth rods work much better than electrically short radials on 136kHz. But when I operate on 160m, radials are much better than the earth rods. My soil is 1m of cl
Received VO1NA last night on 137.777kHz last night but with a lot of fading. Good 2305-0140 then signal went down and noise went up (US sunset?), and a reprise at my dawn 0510-0555UTC, Nothing yet se
Excellent solid signal from VO!NA (without yesterday's chirp) on 137.777kHz from what appeared to be the start of transmission at 0040 until a sudden fadeout at 0620UTC. Still nothing seen from WH2XI
