Holy Cow! Random Wire Calculations Made Easy!

 

TenTecR4030

Been hacking around lately looking for more fun antenna projects to do with my QRP rigs.

In the meantime, I’ve been having a blast with this old Ten-Tec R4030 which I recently picked up.

I’ts been quite awhile since I have been experimenting with QRP antennas or been in the mood to build stuff but lately I have been doing a bit both for some odd reason…

Anyway, to avoid boring you to death with my idiosyncrasies, I have been reading a lot about theory of UNUN’s, random wire lengths and other weird combos or for the nerdy ham in me.

In doing so,  IMHO I found a rather priceless article on random wire lengths.  One of the keywords on the page which lends itself to my idiosyncrasies is UNORTHODOX.  Perhaps you will get out of this article as much as I did. (Yup, I even compiled and ran the C Code on my Raspberry PI!)

The Article is titled Random Wire Antennas. 72 and Enjoy de KE2YK

 

 

 

 

 

The Long Island CW Club – Teaching Morse Code

Long Island CW Club

Portable Ops 40’s Style!

Recently joined the Long Island CW Club. They are a great bunch of guys from Great South Bay Amateur Radio Club who are teaching CW at different levels via ZOOM video conferencing software.

The annual membership is well worth it for those interested in helping others learn CW.

Today the Club attended a quick video conference business meeting followed by a detailed video conference presentation on the reverse beacon network and DX spotting via the DX Summit Web site.

Drake SPR-4 Receiver SOLD!

I am selling a solid state Drake Receiver and Original Manual. To my knowledge, the radio is in good working condition. Cosmetically the radio is clean (minus the dust) as the photos will show.

The radio has the crystal calibrator and Noise Blanker installed. The crystal bank is fully loaded.  To my knowledge the radio works on all bands. The incandescent bulb is out behind the pre-selector and S meter indicators.  The original owner placed a plastic strip of frequencies along the front of the top cover as you will see in the photos.
An inquiry was recently made regarding the purpose of the threaded holes in both sides of the cabinet. I don’t know the reason for them but it is part of the original cabinet when manufactured. I verified that by looking at the cover of the manual and viewing an SPR-4 demo video on youtube.
Buyer pays for UPS packing, shipping and insurance.  PayPal preferred but USPS money order accepted.

If you are interested, make me an offer by email at ke2yk48 at gmail dot com

Here are the what you see is what you get photos. Dusty cover included in price!
