Posted: 23 Jun 2022 01:42 AM PDT
http://g3xbm-qrp.blogspot.com/2022/06/10m-qrp-wspr-tx-thursday.html
Already at 0836z, today is far more promising than yesterday. 3 stations already spotting my 500mW QRP WSPR beacon.

My QRP TX has been on 40.680 MHz USB dial FT8 TX since just after 0800z. Already spotted by HC02 in southern Portugal.

Poor Es day?

Certainly here, today was a very poor Es day, with no spots of me at all on
10m WSPR or 8m FT8.
As the season progresses, I guess we will get more poor Es days. Hopefully tomorrow will be better, although with sporadic-E (Es) things
are "sporadic".
I have seen 6m Es QRP SSB as late as September. The main season is May,
June and July.

10m QRP WSPR TX

Although I have had my 500mW beacon on most of the afternoon, nobody has
yet spotted me. It almost feels as those long days of Es are coming to a
close. Es will still be around, but we have to expect days when it will be absent.
In my experience, I have worked 6m SSB QRP DX as late as September.

Oscar 100 activity

Every few weeks, I give an update on activity on the narrowband transponder
of this geosynchronous satellite. The last time I checked was early evening
in Europe on Wednesday. Activity is still low.
As an example, 3B8GL was calling CQ on SSB with a decent signal for ages
with no takers!

8m experiment (Wednesday)
Posted: 22 Jun 2022 08:03 AM PDT
http://g3xbm-qrp.blogspot.com/2022/06/8m-experiment-wednesday_22.html
Later, I hope to be on 8m TX on 40.680 MHz USB dial FT8 (first). It is now 1243z.
UPDATE 1439z: Now on 8m FT8 TX. Intensely frustrated that in the UK we have
to pay for access to 8m, when OFCOM could have allocated 40.680-40.685 MHs (just 5 kHz), by NoV, to the amateur service, narrow digital only, no
speech, to encourage self training and research. Frankly I find the OFCOM
and RSGB position totally and unbelievably bizarre! No, totally STUPID!!!

Accessing DMR via your PC for free ?
Posted: 22 Jun 2022 12:45 AM PDT
http://g3xbm-qrp.blogspot.com/2022/06/accessing-dmr-via-your-pc.html
There are great opportunities with DMR. However, like many, I have no wish
to get a DMR portable or external to the PC unit to act as a bridge.
What I am wondering is is it possible to access DMR via the PC alone using
some kind of gateway? If you know of a way, please let me know.

10m QRP WSPR TX
Posted: 21 Jun 2022 12:07 PM PDT
http://g3xbm-qrp.blogspot.com/2022/06/10m-qrp-wspr-tx_21.html
My QRP (500mW) beacon was turned on at 0808z. No spots yet of me.
Yesterday, I only had spots from the Canary Isles on 10m. These could have
been F2.
UPDATE 0824z: One spot from Denmark.
UPDATE 1326z: 11 stations have spotted my QRP WSPR today. These look like
Es.
UPDATE 1905z: 38 unique stations spotting my 10m WSPR today. Not bad.

8m experiment (Tuesday)
Posted: 21 Jun 2022 12:32 PM PDT
http://g3xbm-qrp.blogspot.com/2022/06/8m-experiment-tuesday_21.html
My QRP TX was turned on at 0807z on 40.680 MHz USB dial FT8.
UPDATE 0815z: No spots.
UPDATE 1257z: 3 stations have spotted me so far on 8m FT8.
UPDATE 1920z: 6 unique stations have spotted my 8m FT8 TX today. I have
now been spotted in 11 countries. Not bad for a few watts and low wire
dipole. I just wish the UK had a very small 8m amateur allocation by NoV, digital only. Stupid, short-sighted, OFCOM and stupid, short sighted RSGB.
We need self training and research....and real RF engineers!!
UPDATE 1932z: This will probably not happen with my low ERP, but I still
hope for an FT8 spot by a station in the USA. I live in hope!!

Super DX at VHF, UHF and microwaves?
Posted: 21 Jun 2022 12:54 AM PDT
http://g3xbm-qrp.blogspot.com/2022/06/super-dx-at-vhf-uhf-and-microwaves.html
On my website there is a page about super DX on VHF and UHF. Most, or
every, summer there are 6m openings from Western Europe to the Far East.
These are thought to be linked to noctilucent clouds in the mesosphere. It
is possible these openings may occur at far higher frequencies. I am
surprised nobody seems to be trying as there could be new records galore.
I am not sure how FT8 works with noctilucent clouds, although I have
certainly copied Japanese stations on 6m FT8 by this mechanism with a very
poor setup.
