Network radios

A network radio has been owned for several years - 5 to be precise! Mine looks just like a 2m or 70cm handheld complete with PTT and antenna. It has been used on Echolink, and on DMR with an app called Droidstar.

The phone is essentially an Android smartphone, so it can run all sorts of apps too.

I'll be honest, I prefer "real" radio where the link is open to the variations of the ionosphere or troposphere. I can see they have their place where conventional RF radio is not possible such as in hotels or care homes, or where external antennas cannot be erected. At the depths of solar mimima, I can see them having a place too.

10m 500mW WSPR TX (Saturday)

For about 2 hours I have been on 10m WSPR with my 500mW beacon. Lots of Es and F2 reports already as the table shows.

UPDATE 1400z: So far today, 45 unique station spots of my QRP with the furthermost FR1GZ (9724km).

UPDATE 1853z: 48 unique stations have spotted my 500mW 10m WSPR beacon today (see table).

8m QRP FT8 (Saturday)

Since about 0950z, I have been on 40.680 MHz FT8 (DF about 1950 Hz, TX first). It is now 1038z and no spots.

UPDATE 1153z:  Spotted by S50F (1205km).

UPDATE 1402z:  Now EI1CAH (690km) also spotting me.

Stations spotting my 2.5W to
a low dipole on 8m FT8 today

UPDATE  1822z:  6 stations have spotted my 2.5W 8m FT8 to a low dipole today. There are some notable stations missing this year. G9PUV and EI9KP have not been seen on 8m TX this year.  G3WCS appeared briefly earlier in the spring, although I have not spotted him recently. So far, today has been a good day with plenty of Es on 8m. 

Es promising (Saturday)

As the indications are that we could have a decent day in Europe with Es, my proposal is still to try 8m FT8 on 40.680 MHz and 10m QRP WSPR with my 500mW beacon. I shall probably turn these on in the next 10 minutes. Later, I might try 8m WSPR on 40.680 (DF about 1550 Hz)

Sunspots - Saturday May 27th 2023

 Solar flux is 149 and the SSN 127. A=6 and K=1.

8m Saturday

Today seems to have been the best Es day in Europe this season. 

Even on 4m with an 8m dipole (tuned via an internal auto-ATU) I have been spotted widely in Europe and I have spotted 4m FT8 stations all over Europe.

So, assuming Es will be as good tomorrow, I hope to try 8m QRP FT8 on 40.680 MHz. I may also try some 8m WSPR.

I am convinced that very low powered 8m stations operating on WSPR using ISM rules will be widely copied across Europe. 

In many countries a licence is not needed for beacons on the 40.66-40.70 MHz ISM band as long as national rules are followed. In many countries this means 10mW ERP. On 10m WSPR just uWs have spanned Europe. We know from Australia that 5mW of 8m WSPR has spanned 5000km.

10m QRP WSPR TX (Friday)

As my 10m antenna is free, I am on 10m WSPR TX with my 500mW WSPR TX beacon.  Already, a couple of Es spots.

UPDATE 1024z:  Already 10 unique stations spotted.  Es seems good today.

UPDATE 1517z: 31 stations have spotted my 10m 500mW WSPR beacon today. Most are Es. See the table.

UPDATE 2120z:   62 unique stations have spotted me today. I think this is a record number.

4m FT8 (Friday)

 As I have no 4m antenna, I am using my 8m dipole, tuned via the auto ATU in the FT-710 So far just spotted today by G3SHK (200km) and no Es.

UPDATE 0935z: One G QSO with a station in the UK near Coventry - G4AEH (124km) and again a spot of me by EA6SA (1423km).

UPDATE 1030z: 3 spots of me with 2 QSOs, the furthermost being EA6SA (1423km). Several spots of Spanish stations plus ZB2GI (1848m).

UPDATE  1301z:    Spotted by 10 stations on 4m FT8 (see map). As HC02 (Portugal) was concerned by my timing (even though it should be sync'd to internet time), I have just done a re-sync.

UPDATE 2012z: 65 stations spotted my 4m FT8 today, even with my 8m wire dipole (see map)!

Gobbledegook - NOT amateur radio

I have just received an email from Google AdSense and I am none the wiser!  In my view it is total rubbish. To my mind, it was total gobbledegook.  

Please may I have this in plain English?
