QMX+ transceiver

My thanks to Steve G1KQH for bringing this to my notice. 

QRP Labs have the QMX+ multi-mode 160-6m transceiver on sale. Hans makes some really good kit and I have no doubt that this rig will also be great.

6m QRPP FT8 (Sunday)

Yesterday I was surprised how well 6m FT8 worked at 10mW, so I am again trying 6m QRPP (10mW) FT8 today. 

How do I work out 10mW?  The rig is set to the lowest power setting (measured 500mW). There is a 15dB pad right at the antenna connection of the radio. My 6m antenna is fed with RG58 coax with a loss of 2dB at 6m. Assume 0dB gain on 6m from the V2000 omni antenna, although it probably has a loss in many directions on 6m!  

So just 10mW to the antenna.

UPDATE 0855z: Already spotted with 10mW pretty well in Sardinia by IS0AWZ (1599km). Really, with good Es not much power at all is needed! Even at 10mW 6m FT8, I probably had 8dB in hand.

UPDATE 1141z:  8 spots of my 10mW 6m FT8. Who needs power?

UPDATE 1726z:  24 stations have spotted my 10mW 6m FT8 to the V2000 omni antenna. The best DX is western Ukraine. I am amazed how little ERP is needed at times on 6m FT8. Judging by the results on 6m FT8 with 10mW, perhaps I should try 10m FT8 with 10mW?

6m FT8 today

UPDATE 2020z:  I can scarcely believe this!!  My 10mW 6m FT8  has reached Brazil!  In all, I have been spotted by 32 stations today with the furthermost PY1EME (9453km). This is with an omni vertical antenna too!  I guess this was TEP and Es. Truly amazing for a VHF band. The antenna and take-off at PY1EME must help as must the electrically quiet environment. Many of PY1EME's spots were in South America, so I am pretty sure this is genuine.

10m 500uW (0.5mW) WSPR (Sunday)

 10m Es looks promising and my 500uW 10m WSPR beacon is on.

UPDATE 1457z:  Despite Es being excellent today with 24 spots across Europe in 6m 10mW FT8, I have received no spots at all of my 500uW 10m WSPR. This is 13dB less power, but I was surprised that not a single spot was obtained. This must mean (1) 13dB makes a lot of difference, (2) many more are now on FT8, or (3) the 15 second period of FT8 catches more very brief Es openings than the 120 seconds of WSPR-2. It is probably a bit of all three.

UPDATE 1838z:  GM4WJA (624km) has spotted my 500uW (0.5mW) 10m WSPR several times.

Sunspots - Sunday May 19th

Solar flux is 194 and the SSN 166. A=12 and K=1.

End of the road?

Overnight just 2  stations spotted my 10mW ERP 630m WSPR. It looks like the season is ending as noise levels increase over the spring and summer making the reception of weaker signals much harder. It was fun. 

I shall try again in the autumn. 

A new challenge calls!

630m QRP WSPR (Saturday)

My 10mW ERP from the earth-electrode "antenna" in the ground was turned on at about 1910. So far, spotted by just G6AVK (78km).

8m FT8 QRPP under ISM rules

My 10mW 6m FT8  tests have already exceeded my expectations. I am very tempted to try 8m FT8 (not WSPR) at 10mW ERP on under ISM rules. Perhaps I should try to mend my 8m dipole tomorrow?

New ICOM HF transceiver?

On John's blog he mentions a new concept radio from ICOM called the X60. This is on show at the Dayton Hamvention this weekend. The main unveiling will be at the Tokyo Ham Fair later this summer.

The Dayton Hamvention is probably the biggest amateur radio show in the world. 

I have not yet heard if Yaesu will announce anything. Personally, I think they are in a total muddle and it would not surprise me if Yaesu and Kenwood leave the amateur radio market within 5 years.

Blog numbers - NOT amateur radio

One of the things as a runner of a blog I can see is how many visitors I get each day. Basically these numbers are unreliable!  

Yesterday, for example, the number of supposed visitors tripled within minutes only to go down again later. Today I have already well exceeded the number seen yesterday. 

Basically they are rubbish.

European Es

At the moment, things do not look too great. However, with Es, things can very quickly alter, so I shall stick with 10m and 6m QRPP WSPR in case things change.
