The BitX20A and BitX17A are complete SSB kits with board, all parts, digital display and custom powder coated and punched case that is based on the BitX20 that was designed by Ashlan Farhan. Output is about 10 Watts. ... Hamtronics offers a variety of VHF and UHF receiver and exciter kits as well as many other interesting items.
Central Electronics Inc., Chicago is founded by Wes Schum in late 1949. Founded: 1949. History: Wes Shum had always envisioned his company as being a manufacturer of radio communications equipment and had a budding interest in single-sideband even during WW-II. Wes and Joe Batchelor had been working independently to develop amateur single ...
    1. SSB exciter. The exciter is a familiar sequence of microphone amplifier, balanced modulator, then off to the crystal filter and IF amplifier. Upon return the 9MHz SSB signal is mixed with the VFO to 28MHz using another LM1496 Gilbert Cell mixer to get to 28MHz. 28MHz driver and PA. The output device is a Mitsubishi RD16HHF1.
    2. The kit of parts came with two pieces of 10 ohm coax, and one piece of 50 ohm .250 semi-rigid for the output baluns/matching transformers. I make mention of this because, as supplied in the kit, these coax pieces were a couple cm longer than the article specified. ... Since SSB and CW duty cycles are no more than about 50% max, 1.5kw is no ...
    3. A pair of 4 khz usb transceivers. Miscellaneous radio: Reduced bandwidth DATV exciter (146.5 MHz) An analogue, fast responding, high resolution signal strength meter for QO-100. Ceramic resonator SSB filters. 80m Weaver receiver and transceiver - also known as '3rd method'. 23cm PA using Erikson PTF10137 sm device.
    4. In summer after high-school I started building a Phasing type SSB exciter based on a circuit that appeared in the 1965 ARRL Handbook. This exciter was of course tube based. It used a set of coils and trimming capacitors for each band (80,40,20) and I only did the 20-meter band as it was the easiest to do.
    5. May 21, 2017 · RTC03 + BritX (All Band SSB) + Wide BPF/LPF + RF-PA20(4xIRF510), Its almost complete now I got many request from friend to listed full set of transceiver module on ebay. Its already pushing me hard to realize it as soon as possible.
    6. Collection of Amateur Radio Homebrewing Projects. Projects are in E-Books which need to be downloaded and run. Audio Frequency Projects. Antennas for Amateur Radio Station. Digital Communication for Amateur Radio. Hobby Circuits Part 1. Hobby Circuits Part 2. Power Supply Projects. Radio/Receiver Circuits.
    7. Built TAURUS 40m SSB Exciter. As an advanced part of the BARSicle project the plan is to build RV3YF's TAURUS SSB Exciter and 5W PA. I have received the kit for both, and so far built to SSB Exciter, I have made a couple of modifications which I hope will work, these are to include input LPF for the VFO input of 4.0592 - 3.9592MHz (tuning 7.0 ...
    8. The G4CLF Transceiver is the heart of a simple, but high performance, SSB transceiver system developed in the Applications Laboratories of Plessey Semiconductors Ltd in the late 1970s and published in 1980. It uses the Plessey Semiconductors' SL1600 family of integrated circuits for radio systems, which was made obsolete in the early 1990s.
    9. Bitx Multi band Exciter. This is a Bitx Multiband ssb transceiver exciter board for all HF bands from 3.5 MHZto 30 MHZ. Complete manual is available for construction. There are no reviews yet. Only logged in customers who have purchased this product may leave a review.
    On offer is a transistorised 144 / 28 transverter PA unit manufactured by Microwave Modules Limited. The whole unit is mounted in a die cast box which measures about 2.25 inches x 4.50 inches x 1.00 inches; the connections are soldered to connections on the side of the box, two of which are through 'feed troughs'.
TX. The transmitter consists of a TX mixer (NE612) and a bandpass filter on 70 MHz. In the mixer the VCO signal is mixed with the SSB from the exiter in mode USB/LSB, and with a simple crystal oscillator at 10.7 MHz for FM and CW. In mode FM the main vco is frequency modulated by the microphone signal. The mic amp is also on the exciter board.

Enhanced 4 Digit Alarm Keypad. Circuit : Ron J. Description: This is an enhanced 5 digit keypad which may be used with the Modular Alarm System. Notes: The Keypad must be the kind with a common terminal and a separate connection for each key. On a 12-key pad, look for 13 terminals. The matrix type with 7 terminals will NOT do.

Need assistance in finding a 10 meter cw transmitter complete or kit or someone to design one for a BEACON. Currently operating on 28.300 mHz 24/7/365. Need something bullet proof. Something that will idle along with CW at 50% duty cycle at the most at maybe 50-100 w out. I have 9 DEAD HTX-100's under the desk as a tribute to my using that radio for years to run the beacon.
