Storm tonight? - NOT amateur radio

In East Anglia there is thunder, lightning and heavy rain due overnight. Quite often we miss the worst. Just in case, I have disconnected antennas, PSUs and PCs. Some areas are due to get nearly 2 weeks of rain in just a few hours. Better check the rain gauge tomorrow!

ICOM IC-905 GHz transceiver review

The latest RadCom has a review of this ICOM microwave transceiver. 

At £3549.95 without the 10 GHz transverter I cannot see them selling many, let alone make a profit. It would not surprise me if this product quietly disappeared in 2024. There is a theory that this product is a free trial for a later commercial product. Watch this space.

It is an interesting product, but would you pay this much to cover essentially line of site and rain scatter QSOs? Perhaps "appliance operators" with deep pockets might buy as the latest toy.  This is not for me unless a fairy godmother waves her magic wand, HI.

HF, 8m and 6m

 Well, today was pathetic on 8m FT8 and 10m WSPR. 

The main Es season has now ended and the main F2 peak is a few months off. Most of my reports recently on 10m, 8m and 6m with QRP were via Es. 

These openings will occur, but not with the frequency we were used to in May, June and July. Probably 10m FT8 is worth a try as there is far more activity than WSPR. Also, the far shorter TX periods of just 15 seconds means that very short openings may be caught. FT8 is about 8dB worse than WSPR mind you.

OFCOM reminders

This is a weekly reminder that OFCOM updates the data it holds on licences etc. every week. They also have a new publication about 28 GHz satellite gateways. As always, look on the OFCOM website for details.

Anglesey Abbey roses - NOT amateur radio

The roses at nearby Anglesey Abbey are in their second flush and look stunning. The dahlia garden there also now open  ..... at last.

8m QRP FT8 (Friday)

Been on with 2.5W and the dipole since about 0856z, but no spots. 

UPDATE 1627z:   No spots all day again.

10m QRP WSPR (Friday)

Been on 10m 500mW WSPR TX since about 0856z. No spots. 

UPDATE 1304z:  So far, 3 stations spotting me. These look like F2 and not Es.

UPDATE 1840z:  It looks like there was a very late E s opening. 13 unique stations have spotted me. Most of these were just before I went QRT.

8m QRP FT8 (Thursday)

Once again, I am on 8m QRP FT8 on 40.680 MHz USB dial. Most days even my 2.5W to the dipole is spotted across Europe by about 3 stations.

UPDATE 1740z:   No spots.

European Es season

It looks like the main Es season in the northern hemisphere is just about over but, as I remind people, Es can occur at any time. OK, the days when 10m or 6m may be open for hours may be over for this year, but there will still be times.

This is why FT8 can be so useful, sniffing out very brief openings that in the past would have gone unnoticed. Frequently, the 27 MHz CB band is busy, yet 10m is quiet. This suggests decent propagation, but a lack of activity. These days, there is little excuse. Just 15 seconds of FT8 transmission is all that is needed to prove a path is "open".

10m 500mW WSPR TX (Thursday)

My QRP 10m WSPR beacon was turned on at about 0850z. No spots yet.

UPDATE 1034z:  Just spots by local G4KPX (14km). No Es.

UPDATE 1741z:  Spotted by 3 stations. Marginal conditions.

Sunspots - Thursday August 17th 2023

 Solar flux is 180 and the SSN 140.  A=8 and K=1.

ATS120 Receiver

This is a handheld radio available from AliExpress for less than £67. I have no idea how good it is. The Chinese will soon will be a real challenge to the Japanese in the years ahead. In my view the Chinese have more work to do on quality control, but they will get there.



Any ideas? - NOT amateur radio


Most definitely I am no flower expert! We saw this on our walk this morning. It had flowers about 5cm long. I expect some expert will say it is "common xxx" and they are widespread!! 

Wicken Fen walk - NOT amateur radio


One of our favourite walks is to Wicken Fen where we get a coffee and something to eat. At least the sun was shining today! 

10m 500mW WSPR TX

My 500mW 10m WSPR TX beacon has been on since about 0900z. At 1217z, 4 stations have spotted me

UPDATE 1555z:
38 unique stations have spotted me today.

8m QRP FT8 (Wednesday)

Once again, I am on 8m QRP FT8. As the Es season is drawing to a close, it may be harder to get spots now.

UPDATE 1221z:  No spots.

UPDATE 1443z: Spotted by EA3ERE (1153km).

UPDATE 1619z: Spotted by 3 stations. (see map).

Sunspots - Wednesday August 16th 2023
