We've done everything possible to make this an easy kit to build, and an excellent radio to operate. Some of the major features of the OHR 100A are:
All wiring to the single PC board is terminated with pre-assembled Molex connectors, rear panel connectors and controls are mounted on the circuit board..
If you'd like to view a block diagram of the OHR100A, click here.
An oscilloscope is NOT needed for alignment. We have provided DC test points on the board for use with your digital voltmeter during alignment. 3.5mm jacks are provided for headphones and speaker. There is also an on board shorting plug to select stereo or mono headphone operation. There is room filling audio available at a separate speaker jack.
The OHR 100A will operate on 12
- 13.8VDC. The current
drain is 80mA on receive and 850mA on transmit with 13.6VDC supply
The 15 and 40 meter versions are easy to set up for operation in the
portions of the band.
For finer tuning, a high-precision ten turn pot is available (part number MO-100AP). It's supplied with a matching knob and instructions for $15.95. Note that if you install the ten turn pot, the front-panel dial markings will no longer be relevant and use of the DD-1 digital dial is recommended.
The power LED kit is optional because it will increase current requirements by about 50mA on both receive and transmit. It requires drilling a 1/4" mounting hole in the front panel but is otherwise a very simple and attractive mod based on a pre-wired LED and bezel assembly.
The OHR 100A comes with a high qualtiy SO-239 antenna connector. But if you would prefer a BNC connector, you'll find a conversion kit on our Parts Page.
The completed transceiver measures (HWD) 2 1/2" x 6" x 6" and weighs 24 oz. The kit is complete with cabinet, high quality silkscreened and masked PCB, all components and instructions. Click here for information about the optional keyers.
