Unfortunately, all of these kits use a little PC board made by a ...A ham radio transmitter is a device that transmits ham frequencies to other ham operators. You can use it in two different ways: - External Transmitter - An external ham radio transmitter attaches directly to your antenna, so you will need an outdoor antenna or a very long indoor wire for this type of setup.Drill 1⁄2 inch (1.3 cm) holes using a good drill bit, and never drill close to the end of the pipe. About 2 inches (5.1 cm) from the end gives you a good spacing for the insulators. For the feed point, use yet another piece of PVC pipe, drilling a hole through the center to provide for a strain relief for the feedline.RockMite Mixer. The direct conversion receiver mixer. The signals come in on the left and go left-to-right. The point (A) on the diagram is a connection to the antenna. That is the source of our CW signal. It travels through a capacitor C1 to AC-couple the signal to the remainder of the mixer.Squelch A user-adjustable electronic circuit in a receiver or transceiver which masks unwanted noise in the absence of a signal.
