Third Time Out with the 20m EFHW Antenna

Setup the 20m EFHW as a vertical on the 30ft travel mast as before. The mast is lashed to a chain link fence post and the match box is just off the ground. Checking the antenna at the feed point with the Mini60 antenna analyzer showed a bandwidth of 588 kHz with a 1.11 SWR at 14.175 MHz. The antenna is resonant across the 14.150-14.350  Mhz voice band. Then through a 50ft piece of RG-8X coax the SWR increased to 1.24 but the antenna remained resonant. Here is the station in operation:

There was a couple of QSO parties going on this afternoon so there was a rich field of domestic contacts. I operated at 45W using the FT-817ND and the amplifier.Partly cloudy day today so there were period with no direct sunshine. The following power statistics were noted:

After 1 hour Solar panel provided .644Ahr and the rig consumed .380Ahr

After 2 hours Solar panel provided 1.146Ahr and the rig consumed .904Ahr

I was unable to take a final reading as I accidentally pulled the plug on the solar panel erasing the counts. The 52W fold up panel was able to keep up with my duty cycle at full 45W.

I operated for 3 hours and made 16 QSO’s mainly in the Washington State area.No difficulties at all making the contacts and received solid 59’s across the board. Propagation during this time favored North America but Europe started opening up towards the end. I was able to copy QSO’s in progress with stations in Italy and Germany. I was not able to break the pile ups though.

All in all I am impressed with the performance of this antenna and with the ability of the solar panel to let me operate for an extended period even with periods of cloudiness. Here is a view of the antenna and the antenna fed point.

    How do you find the speech compressor? I have the same kit to complete this weekend.
