Notes: tinySA

Loading

I still want the expensive HP type of Spectrum Analyzer, but alas, I doubt I will have $40,000 bucks to throw at it.  When I saw the “tinySA”, (tiny spectrum analyzer), come to market a few months ago, and saw that R&L was selling them for $54.98, I just had to have one…  This entry is a string of notes that may help the next person along this route to get to a working, fully updated, with tools tinySA.

Notes on tuning a Hustler 6BTV

Loading

I thought I would share a few of my notes on tuning up a 6BTV antenna, and constructing a radial field.  I have been using a GAP Challenger DX, (review here), for the past fifteen years, unbeknownst to me, and over that time, water had been slowly seeping into the tuning harness of the antenna.

Review of the Palstar AT2KD Tuner

Loading

Over time I have had both auto tuners, and manual tuners. I have used differential tuners, and standard tuners… I always return to manual tuners, using roller inductors, and large caps every time… An auto tuner is simpler to operate, but the power levels just are not there yet for me on anything I can afford, nor have I been able to get an autotuner, (of the ones I have used), to tune to an exact 1:1, every time, on every band. It is always something like 1.x:1, I have seen as high as 1.7:1, which can cause issues with the new solid state amps, such as the ALS-1306, which I own. See the section under “Conclusions”, for more on that subject. Continue reading »

Adding an external keypad to the K3

Loading

The Genovation keypads have either forty eight or twenty four keys on them depending on which model you purchase. Each individual key can be programmed to send a single character, or a series of characters. Further, each key has a removable plastic cover so you can put a label under the plastic. All of this allows you to program a key, then label it, then use it to send a macro trigger to the P3. Like the P3, the Genovation also needs to be programmed in advance of use. Fortunately Genovation provides a rather nice piece of software with each keypad for just this task. Once a key is programmed, if you tap that key, the Genovation sends out the character(s) you pre-programmed into it via the USB port. This lends itself well to the function of sending macro triggers to the P3. Continue reading »

I have RFI, now what– Part I, Locating it

Loading

This allows me to verify I am working with the same RFI source. I record the audio from the FT-900, and then I can play it back into Spectrum labs, and see if it matches the RFI I am hearing at home. Once I have a match, I know without a doubt I have the same source. I then look at the map, and it becomes pretty obvious where the RFI is most of the time. I next start running the frequency up as high as possible and still hear the RFI. I then grab a Google Map of a smaller area, around where the signal is strongest, and do the drive around again. I repeat this process moving ever higher in frequency. Continue reading »

The Bulliten starts off with “DX This Week”, and is a recap of what DX was active in the past week. It provides general information on many, many DX stations. Continue reading »
