GPG Transition Statement

Hash: SHA256

Hash: SHA256

Date: 03-JAN-2020

For a number of reasons, I have recently set up a new OpenPGP key,
and will be transitioning away from my old one.

The old key will continue to be valid for some time, but I prefer all
future correspondence to come to the new one. I would also like this
new key to be re-integrated into the web of trust.  This message is
signed by both keys to certify the transition.

The old key was:

pub   rsa2048 2011-10-24 [expires: 2020-01-31]
      6D7A 332C F930 D2A2 C857 72AE 2B11 00DF D585 60BA

And the new key is:

pub   rsa4096 2020-01-03
      81F1 E73D 6EF2 B5D4 BF7B 8948 1329 D7FF 911A DAB9
To fetch the full key, you can simply do:

  curl -sS | gpg --import -

If you already know my old key, you can now verify that the new key is
signed by the old one:

  gpg --check-sigs '911ADAB9'

If you are satisfied that you've got the right key, and the UIDs match
what you expect, I'd appreciate it if you would sign my key. You can
do that by issuing the following command:

  gpg --sign-key '911ADAB9'

I'd like to receive your signatures on my key. You can send me
an e-mail with the new signatures (if you have a functional MTA on
your system):

  gpg --export '911ADAB9' | gpg --encrypt -r '911ADAB9' --armor | mail -s 'OpenPGP Signatures' 

I also recommend reading:

Please let me know if you have any questions, or problems, and sorry
for the inconvenience.

Hustler 5BTV Vertical Install: Part 1

So, I have decided to start installation on a Hustler 5 Band Trapped Vertical (5BTV) for HF from DX Engineering. At roughly 25 ft tall, this antenna will allow me to work 80, 40, 20, 15 and 10 meters.

I started by digging an approximately 6in deep trench for some 3/4″ conduit for the coax run. My plan is to install the antenna in the round planter pictured, so that when the install is complete it won’t affect foot, mower, or other traffic. I occassionally drive through the back yard with my truck, mainly to park the trailer and load/unload yard debris and other items; so I couldn’t install it in the grassy areas of the yard. Also, with the limited trees and their positioning, I am restricted on the usage of dipoles or other wire antennas. The best option I have come up with is an OCF dipole, installed between my tower and the neighbors tree; however, they have mentioned interest in completely removing that tree.



Once the conduit run was finished, including backfill and reseeding the grass, I dug a 4ft deep hole with a post hole digger/shovel for the main “mast” pipe, and drove a 5/8″ 8ft ground rod. The “mast” pipe sticks out of the ground approximately 22″ (instructions recommend between 20″ and 23″ above ground) and is a 1-1/4″ galvinized water pipe that is 5ft long. I put a little gravel in the bottom of the hole, stuck the pipe in, and backfilled with concrete. I checked for plumb on 2 sides of the pipe (90 degrees apart) to be sure it was properly installed.

The final picture shows the “mast” pipe, the ground rod, and the conduit.

Coming Soon – Part 2: Radials, radial base plate, and coax run.

Motorola MDC-1200 Radio Numbering Scheme

If your agency, or business is using Motorola MDC capable radios, then you can utilize this numbering scheme. This makes it easier to identify what type of radio and which unit # or radio # is transmitting at any given time.

I recommend setting MDC to “post only” which will make the radio transmit the MDC at the end after the user releases the PTT on the radio.
