Getting on
The 220 Band
:: This file is a work in progress ::
| This page is dedicated to promoting
increased use of the 222 to 225 MHz Band. Why ?
1. It's a great band, with
characteristics similar to 144-148 MHz, and has certain real advantages
over the 2 Meter band. Most amateurs, especially those newly-licensed, get equipment for the 2 Meter band. Manufacturers put out lots of neat rigs for this band, many paired with 440 capability, and they generally have put the 220 band on the back burner (not totally, as you will see below). This all goes back to the early days before amateur rigs were available for VHF and when commercial radios could be readily converted to 144 MHz, and not so easily or not at all to 220. So, lots of hams got on 2 Meters with converted gear. Eventually manufacturers started making rigs for 2 Meters because they saw that the market was there. The same sort of thing happened on the 440 band. But a few manufacturers made equipment for the 220 band, and some amateurs discovered what a good VHF band it is. Some of us used the Midland 13-509, a 12 channel crystal-controlled 10 watt rig, still good today. The Clegg FM-76 is a comparable rig. There is also the Midland 13-513, a similar but synthesized transceiver, 20 watts. Many amateurs when asked why they don't try 220 say 'why should I buy another rig when nobody is on the band, and there is hardly any equipment available for 220'. Why you should make a move to get on 220 is noted above - and there are amateurs on the band. The perception that there is hardly any commercial gear for the 220 band is a fallacy, and new equipment is available - some at very attractive prices. There is equipment out there that you can use for weak-signal work as well as for FM. Serious VHF contesters have already made the effort to get on 220 using SSB and CW, for the extra multipliers.

available, you say? Check out the following, compiled by Ted,

A Useful Book, if you can
find it - Transverters - The following transverter designs use a 28 MHz transmitter/receiver to generate and
receive 222 MHz signals. You do have a 10 Meter rig, don't you
? A Radio Shack HTX-100 transceiver makes a good interface rig for
these transverters. There is a design for a no-tune transverter for 222 MHz on the QEX CD-ROMs from ARRL. This was designed by Jack Lau, W1VT, and was described in the July 1993 QEX. The tuned circuits are etched on the circuit boards. The pc boards for this project are available from Far Circuits. Rick, VE3CVG, has notes on the construction of this transverter at More info on my 222 Xvrtr project . Down East Microwave Inc. has a transverter for 222 MHz, the 222-28, which is available already constructed or in kit form. Transmitter,
Receiver and Transceiver Kits - Ten-Tec offers the model 1230 synthesized transceiver. This rig has 20 watts output. If you plan to build an FM transceiver, check this one out first. See also Hamtronics for their T301 and TA51 transmitter and R301 and R100 receiver kits. VE3BYT
