|Easy build. Just a few holes to drill, a few components to mount
and solder. Result is a 50 ohm 5 watt nominal dummy load for
testing your qrp rig. Requires coax output from your radio. Actual
output watts can be read from a digital voltmeter per included
instructions. Must cool down between readings. 5 watts nominal
output maximum recommended.
|QRP 5W Dummy Load Kit now with wattage detection circuit. Includes "Altoids" style tin 'box/container" Instructions, parts, professional looking. Requires
minimum assembly and soldering. Good for 5 to 8 watts max between cool down. Connect your voltmeter to read power in watts. $15.00

|The Pastime Projects coil form is available either glued or unglued. The joint is edge glued between the form and the octal base.
While the coil forms of old may have used 4 pin or 5 pin sockets, these have become scarce. The use of the octal bases makes more
sense and gives us some choices in the amount of taps and/or coil windings we can combine on one form. An obvious disadvantage
of the octal socket is more friction in inserting or removing the coil form.
We have found the extra unused pins can be carefully cut off. We have easily removed every other pin and ended up with a 4 pin
socket which is much easier to work with. It still allows the alignment of the coil into the correct pins in the base because of the keyed
center pin on octal bases. You can choose how many pins you need on your project.. We remove pins 1,4,5,and 7 in our products.
If you prefer, of course, you can build with all pins intact; just insert and remove with care.
The 8-pin plug-in coil forms fabricated by Pastime Projects have been glued together using Loctite Stik n’ Seal Non-Toxic
adhesive manufactured by Henkel Corporation Avon Ohio. www.loctiteproducts.com
The resulting bond has proven quite strong on our coil forms. If the bond should break, we would recommend you simply re-glue
using the above product or similar suitable adhesive. Parts should be clean before gluing.
Please tell us about your experience with these forms. If you have any suggestions for improvement, we would like to hear from you.
