Special Sales page of www.pastimeprojects.com

April 13, 2013

Our current Special Sales page on http://www.pastimeprojects.com currently includes two pieces of equipment of interest to the radio amateur. An Eico 723 CW Transmitter and a Realistic DX-160 receiver.
The Eico was purchased at a hamfest. It tested ok as received. We bench tested it and replaced the filter capacitors which were the originals. We tested it into a dummy load on 40 and 80 meters while monitoring it on both commercial equipment and modern radio amateur recievers. All looks well. The Eico had been repainted and the appearance is great. Please contact us for further info. We want you to know what you are buying. We prefer selling this to a licensed ham who has experience with tube type transmitters. Transmitters can be damaged if not properly tuned. The other item, a Realistic DX-160 receiver came to us working but with no audio. Many hours later and with replacement of approximately 15 components, we have excellent audio.
While we have not fully calibrated either unit to original specifications, we think these are great values. We will warrant
these as working at time of shipment. The prices are negotiable.

More good news for Pastime Projects Crystals

April 4, 2013

We have been checking out an Eico 723 60 Watt CW Transmitter manufactured in the late 1950’s and 1960’s. To check this out we pulled one of our 40 meter 7.03 mHz crystals from stock. This is one of the FT 243 WW II type holders with a new hermetically sealed cystal installed inside. The transmitter sounded great with no drift, chirp, or other problem.

The Eico oscillator circuit looks just like the “grid-plate” type oscillators so common to designs in the Handbooks starting in the mid 1950s. This same oscillator type design is used in the Ameco AC-1.

If your boat anchor tube type amateur radio trasnmitter is from the 1950 era, chances are it has the “grid-plate” type oscillator. If it does, our crystals should work very well…

Again, if you are running a one tube transmitter, you may want to add our “crystal saver” incandescent lamp in series with the crystal. This may prevent loss of the crystal from excessive
current. Best Regards Glenn pastimeprojects at yahoo dot com

April First News Release Miniature Antennas

April 1, 2013

A friend wrote me this April 1st morning. Seems the weather had improved enough to allow him to get outside and work on his miniature magnetic capacitive semi loop antenna.

I wrote back to warn him:

“Just a warning to you Bill (name changed to protect the innocent) with your experimentation with reduced size antenna. Seem the more miniturized the antenna becomes the more intense the wave field. Sue my XYL, as you know, makes ear-rings out of radio parts. She has done this for years and sells them at the hamfests we attend.

Last autumn, as we were passing the broadcast tower of WCRP Cincinnati, She said she was picking up a signal. She was hearing the broadcast through the ear-rings! This continued half way through
Kentucky. This was done with nothing other than the two ear-rings. They had mini torriods, capacitors, and an LED or two…

We thought nothing more about it until two days later when we found She had sufferred RF burns on both ears. With a few days application
of Bag Balm Sue was back to normal.”

Please share this warning with your fellow amateurs. Be carefull out there! 73 Glenn NN8G pastimeprojects(at)yahoo(dot)com
