Pacificon 2017

I will be presenting during the Pacificon 2017 Antenna Forum on Friday, October 20, from 3:30 – 4:30, and my topic is “Low Band DXing Antennas”. I will start with a survey of all of the low band antennas that you should consider for DX-ing on the bands 160 – 30M, and I will include transmit as well as special receive antennas. The presentation…

KY6R FSM Test

I’m using the simple 1979 “RF Sniffer” circuit and I’ve found that the minus line of the meter does add a lot of signal when you plug in a test lead and use it as a radial / ground plane. One really great use is to see how much radiation emanates from an amplifier at various power levels, and where the “drop off” is…

Countdown to Autumnal Equinox 2017

from NJ.COM . . . At 4:02 PM EST, the sun will be directly over the equator – meaning there will be equal daylight and night time world wide. I’m up with a cup of my favorite French Roast listening to FP/G3ZAY fade, and with high hopes that the T88 fires up soon. They are both in my grey line sights. Last night, I…

The “Dirty Dozen”!

I’m now on a jag to get to 90 with only 10 left to go. T88XA was spotted this morning after my sunrise – so that’s one that should be easy. 5T5OK will require serious luck as I have not yet heard them, VK9XI starts up in less than 2 weeks, CT9 is a possibility, KG4HH another in October, VK9CI in October, A52SJ –…

40M KY6R Antenna “Shoot Out” – Initial Test Results

Just two American “Presidential Hopefuls” dueling. Some things never change . . .  I just got home from a week in Montana, Idaho and Washington (Spokane) and “magically” my DX Engineering DV-40-P worked. I am sure its an intermittent connection of some sort, and luckily, Bill, ZS6CCY was able to do some serious on the air testing with me. I also did several tests…

The Best Two Antennas I Have Ever Had

For all low bands, 160-30M, my own designed “Modified Bobtail” is a very clear winner. I’ve blogged extensively about this antenna, and the best antenna tuner for this antenna – and my favorite antenna tuner of all time is the Palstar BT1500A. Every feature, knob and button is useful and perfect for the Mod Bob. The best yagi antenna I have ever had was…

ZS3D and ZS6CCY on Mod Bob – 40M

Dani, ZS3D and ZS6CCY were 59 on the Mod Bob tuned for 40M, so I have just confirmed that its as good or better than the broadside direction on the DX Engineering DV-40-P. I broke through small pileups and was first in in both cases. What was especially cool was that this was during a major solar storm – with a radio blackout in…

Mod-Bob vs. DX Engineering DV-40-P

My DX Engineering DV-40-P 40M phased array just gave up the ghost (SWR went high and there is no directionality), and while its most likely a gopher who has chewed on a wire, the two elements are really too close to the Mod Bob. It is possible (but much less likely) that transmitting on the Mod-Bob has fried a component in the DV-40-P.  Since…

Field Strength Meter

I’m going to use this new old stock Simpson panel meter for a field strength meter. I’m thinking of making it Arduino or Raspberry Pi based so it can be made wireless – have the sensing circuit out in the yard and it sends data and have the meter in the shack. Kind of a weird digital – analog mash up. There are many…

Two Hybrids: 30M and the Mod Bob

The Mod Bob models best on 30M, and it matches the gain I get on my DX Engineering DV-40-P phased vertical array. The pattern is very close to a Bobtail Curtain on 30M, but I think its more like an Extended Double Zepp if you just look at the horizontal part, and almost three elements phased almost like a Bobtail if you look at…
