Another new DXCC entity on the air: KH8 Swain’s Island

I’m glad to hear that there’s another DXCC entity on the air: KH8, Swain’s Island. In fact, I listened to the pile-up on 20 meters from my car last night as I was driving home. Complete chaos. The funny thing about these recent pile-ups attributed to new DXCC entities (Swain’s and Montenegro) is that they [...]

Propfire HF Propagation Monitor update 0.73.5

I had another question regarding the installation of Propfire. It seems that there were a few things I needed to do to the installation part of the extension in order to facilitate automatic installation via my Propfire page. So, after some server tweaking and script updating, version 0.73.5 was created. It doesn’t add any bells [...]

Choosing a Ham Radio Rotator: AlfaSpid, ProSisTel BigBoy, M2, HyGain, Yaesu

There are several tough choices to make along the way in putting together a full-scale amateur radio tower project:

Antennas

bands
performance expectations (gain, F/B, etc.)
type (quads, yagis, log periods, etc.)

Tower decisions:

type (guyed or self supporting)
height (mast height and type)
location

Other things that don’t seem as important at first glance, but are actually relatively critical

coax
rotator (aka Rotor)
building permits
XYL permissions

To [...]

Montenegro DX Festival 2006 hits the ham radio airwaves

A newly minted country means a new DXCC entity – Montenegro. The three week long DX festival from a brand new country in the balkans has started off with massive pile-ups thanks to what must be a dream station. Today, I’ve heard the 4O3T station working 20 meters for the second time. Although the operator [...]

DXing from the bottom of the solar cycle

We’re virtually at the bottom of the 11 year solar cycle, but my mind is on DX. Kinda sounds crazy for a guy with a simple HF mobile antenna system (High Sierra Little Sidekick screwdriver-type antenna) and just as simple home QTH antenna (Butternut HF6V 6 band vertical). Here are a few reasons my ham [...]

Microphone input to PocketPC PDAs

While investigating options for getting audio into the PocketPC for use with PocketDigi, I discovered that quite a number of PDAs offer the 4 conductor cable (3.5mm) which can be used with an adapter cable which splits out the mic-line. Perfect for use with PocketDigi and the Tigertronics SL-1+.
Check out this from the guys at [...]

Propfire HF Propagation Monitor update

Today I decided to clean up a few things in Propfire (my HF Propagation Extension for Firefox) that have been bugging me.  The number one thing was a glitch that cause the extension to not initialize itself until the user had pulled up a menu item for a full propagation report. I think in previous [...]

Tigertronics SignalLink SL-1+ Icom issues

Just ran into a roadblock with the SL-1+ and my pair of Icom radios. I have the Icom IC-746 at home and the IC-706 MKIIg in the car. The idea was to order the Tigertronics unit with a connector that would allow it to work with either radio. So, when ordering the unit, I checked [...]

Tigertronics SignalLink SL-1+ Construction

Spent some time today working on the Tigertronics SL-1+ in an attempt to interface PocketDigi software on my iPAQ 2215 to my Icom. The SL-1+ goes together quickly, but with the Icom and the 6 pin connector, I must provide power to the unit. That meant a trip to Radio Shack for a connector, [...]

Field Day 2006 with the Cyclone and Story County Amateur Radio Clubs

I was able to spend a little time with the Story County ARC for Field Day this year. Unfortunately, the timing was poor as it coincided with my high school class reunion. However, I was able to be there for some of the setup and an hour or so of operating and talking to the [...]
