More night, less daylight = Better HF conditions!

3.925 MHz on the IC-7200

Here’s the good news about the autumn equinox here in the center of North America:  HF conditions are getting better quickly.

With the longer nights and shorter days we are beginning to see fewer thunderstorms with less QRN on bands like 75, 80 and 40 meters.  In fact, absorption is far less as well, and that means the 75/80 meter band is open more hours.  If you are interested in working all states, that’s your band.  You’ll have to start listening early in the morning before sunrise.  Here at WA0TDA, which is east of Minnesota’s capitol of St. Paul, it is easy to hear stations across the continent before sunrise.

Don’t forget to try CW.  The WA0TDA HF remote is CW-enabled.  You can use the RCForb Windows application or the RCForb Android app, which is under $10 in the Play Store.


Maintenance outage – Post-Field Day

Now that Field Day is behind us, the WA0TDA HF remote will be down for routine maintenance.

Bad HF Conditions Persist

Conditions on the HF bands seem to be pretty bad, then they get even worse! Noise abounds as oddball skip conditions make for some surprising HF paths on 80 and 40 meters.  Many days 20 is unusable except for digital on 14.070 MHz.

It’s not pretty.

Consider listening early in the morning and in the evening on 80/75 meters. This band is good throughout the solar cycle, but only if daytime absorption is not too bad.  That’s why you need to get on early in the morning or after dinner!  Give it a try and you’ll be surprised at what you can hear.

HF9V vertical now in use

The WA0TDA IC-7200 station is now using a Butternut HF9V vertical antenna, ground-mounted over a large radial field and fed underground with hard line. The antenna tunes 80 through 6 meters. Press the “Tune” button to activate the antenna tuner for best results.

Antenna update – inverted vee

The inverted vee Maypole antenna is in place at the WA0TDA HF remote station. The antenna tunes 80 through 6 meters, and will be the default antenna most days at the station. On occasion the Butternut HF9V will be used for lower angle performance, and I’ll try to remember to make sure that the station’s system text box greeting in the RCForb software mentions the antenna that is in use. For 20 meter DX the vertical often has quite an advantage.
