An oldschool Imax 2000 is a solid vertical endfed solution for 10m, but also sufficient in resonance for the 15m band. Wideband for sure on 10m, with a good radiation pattern for DX.
Now, I tweeked the SWR a bit better for 15m by the lenght of the top section, so the reflection dropped below 1.3 in the phone section of that band, moving the rings way up to keep it fine in the 10m band. Changing the inductance factor here, on this glassfiber whip ;-), getting the best of both worlds.
The base of the antenna is also at a 15m hight in wavelenght.
Made some QSO's on 8W with CS7/DO5EB and R6OBP for a test, propagation not being at it's best about an hour ago.

Life is good !! 73 !

The X6100 down to it's minimum on 10m !!
Got a 11m telescopic laying around so I decided to make things work as a "pedestrian QRP " unit :-) .
The LiPo battery fits your pocket and I ran this like a walky talky, after some antenna tuning. Now, by looking for the SWR dip ( the R1CBU firmware offers a nice interface to do that ), I saw it becoming resonant in my hand after shortening the antenna by 2 segments. Being the counterpoise myself, it is reasonable at a max of 1:1.5 over a bandwith of 400 khz.
When you put it down, the SWR stays ok, but it becomes narrowbanded ! With the ATU on, you really go down to a perfect result, but it's perfectly manageble without.
Sooo, a cheap 30 euro telescopic for 11m is my new adition to the "micro-kit to go".
Did some FT8 with it this afternoon with the R1CBU firmware on the X6100, on 3W.

Life is good, 73 !!

Rain is pooring down this evening, high winds are gone.
Running the CQ calls in auto, why not... for a change ;-)
At a modest 20W on 20m, resonating on the vertical CP6SR2 multibander.

Back to the roots today !!
Plugged in a 11m transceiver today, stuff laying around, for fun.
I spend decades on 11m before I became a ham operator and all HF bands are filled with contests today.... not my thing.
This tranceiver is a genuine President George II, not being messed with, so I managed to get a solid 10W PEP out of it on SSB ;-)

Just crazy to make a couple contacts with it on channel 39 with operators from the States, good propagation on 11m taday. I made so many contact on QRP in those days, literaly with 5W or 10W on some dipole wires.

Never forget where you're coming from.
73 !!

First time into the small state of Lichtenstein on 20m for me ;-) , thx HB0WR !

15m is open, using the CP6SR2 antenna.
Nice contact with the beautiful island of Madeira - CQ9A on the Yeasu FT891.

Life is good, 73 !!!

The 1.0.7 firmware upgrade for the X6200...
Installing and upgrading : no issues.

Activating the 3D waterfall is kind of tricky : selecting the 3D option in the GEN menu, gives an empty waterfall display. No worries, leave it selected and turn the unit off. After turning it back on, the 3D waterfall appears.
The battery indicator issue is fixed, I tested it with my 3 battery packs. That was a uge problem, glad it has been taken care of.

That 3D waterfall is kind of a gimmick to me, but that choice might be different for you.

73 everyone !

No no no.... not quiting the game here ;-) .
All my antenna's are rebuild for quick removal and deconstruction in partitions, with a reason...
Got a lot of radiators broken here in the past during high wind and storms. Specially the long HF vertical antenna systems and horizontal radials. Wind seems to circulate here like madness.
The weather forcasts are clear about another heavy storm coming up, so... within 15 minutes everything is indoors.

HF remains operational on the wire antenna's ;-) and a V200 for UHF-VHF operations.

73 !!!

Awsome QSO on 10m this afternoon, from the site of the Vlooybergtoren (Tielt-Winge, Belgium ), with my micro- kit", as I call it ;-) !!

Best QSO of the day : A 10 minute contact with WY7AC in the States, with a S55/R57 in beautiful conditions, running the Xiegu x6200 with the basic telescopic antenna and 1 wire radial.

These are the days !! QRP LIFE !

Monitoring HF and a repeater at the same time ? :-)
After getting the weird 3.5mm jack issue fixed for the antenna, it runs great !!!

15m is noisy on my side, but opening up for QRP ;-) , it has been a while !
Working the vertical CP6SR2 today on 8W.
73 !!!

QRP from the Ourthe riverside in our Belgian Ardennes !

Got the Diamond V30 dualband antenna up making connection to the VHF relais of ON0LTV Baracque de Fraiture possible with a CRT portable unit, nothing fancy but solid !

With the CP6SR2 telescopic in front of the caravan, I worked 20m and 40m. Not a walk in the park again on 5W, due to the load of contest activations... propagation was solid on 20m but loaded to much.
Adjusting to 10m, the activation was saved ;-) .
R1CBU firmware runs fine !

Life is good, 73 !!
