40 Meter Top Loaded Vertical
Works good using 20 watts into the East Coast and Ohio this morning
I use #18 for 100 watts and and a #22 for QRP

Field Operations Radio Checklist
Get outside and operate from a park, a picnic table, your backyard, or rest stop mobile.
Choose QRO or QRP operations
QRO – Get a 100W portable transceiver like a Yaesu FT-891/857D/897D, Kenwood 480SAT, or Icom 7000/7300. Get a 100W antenna like a SuperAntenna vertical, Chameleon Antenna, Buddipole, Dipole, or Hyend end fed. Get a 12V 30/20Ah Lipo battery like a Bioenno or a 12v car battery.
QRP – Get an Elecraft KX2/KX3 or a Yaesu FT-817/818ND. Get an Alex Loop, LNR Precision end fed or a dipole. Get a Zippy Flightmax 5000 mah 3S1P 20C battery or a Bioenno battery.
Thanks to Bonnie for clearly explaining what all this solar index stuff means
40m has been opening up in the evening and even cases of 20m opening up in the evening. 20m has become a daytime DX band lately and when conditions are right 40m is showing VK and European stations. The following explains why
How To Read HF Propagation Numbers
The A index = LOW is GOOD.
1 to 6 is BEST
7 to 9 is OK
11 or more is BAD
SFI index: HIGH is GOOD.
70 NOT GOOD
80 GOOD
90 BETTER
100+ BEST
K index: LOW is GOOD.
0 or 1 is BEST
2 is OK
3 or more is BAD
5 is VERY VERY BAD
A low “A index” is most important!
For Low Power Portable DX openings at 10MHz to 30MHz, look for an A index LESS THAN 6.
73—Bonnie KQ6XA
Right NOW the conditions are: A-SFI-K=OK, Not Good, Best
Data provided by N0NBH |
SFI=75 / SN=27 / A=3 / K=0.
A-SFI-K=Best, Not Good, Best …………means bands are open for DX (usually)
