I always searched for a schematic based on transistors to start my first direct conversion receiver. de Our goal is to create a fully functioning "Minimalist" SSB transceiver using something different than the currently popular bilateral (Bitx) topology and in doing so use the minimum number of transistor devices. May 12, 2019 · After having cured that I found the output was 5 to 6 watts PEP output (very clean). The upgrade wasn’t quite as easy, though. It uses The electronic circuit Jan 17, 2025 · Sputnik regenerative receiver has decent receiving capabilities. A transceiver was described in the ARRL SSB Handbook using bipolar transistors. I have uploaded the GRC file to the server, but note that the AGC is currently fixed at medium. be bi-directional. Both operate at the 455-kHz IF frequency and will only need The receiver, despite its simplicity and without the need for any special communication radio components, has surprisingly good reception characteristics. Apr 8, 2010 · Receiver V0. L. A maximum of four active components can be used, inclusive the low frequency amplifier. Traditionally, SSB has been created and received using narrow bandpass filters, or by using a "phasing method" requiring a 90 degree phase shift network across the audio spectrum. Feb 2, 2015 · An SSB transmitter is simply the SSB receiver in reverse. all of the usual operating modes in HF amateur radio. 5.

Feb 12, 2014 · With a receiver, you're faced with all that is there on the band. SSB and CW receiver 10 kHz to 30 MHz This receiver was made with use of the experiences of my first receiver. The second signal mutes the receiver. The RF and AF ports are inputs and outputs depending on the configuration. e. The idea for a Minimalist SSB Transceiver came up when I tried unsuccessfully to build the three tube IMP SSB Transmitter from W4IMP (SK). Oct 31, 2024 · Watch this new video here and there will be a new article as well, based on this regenerative receiver design. Stage 3 wi Fig. Oct 31, 2024 · Andrei – YO6TJJ designed this simple direct conversion receiver with an MC3361 and an LM386. 5 of the simple SSB receiver. IF is 3. 0 MHz range, passes through a two-circuit band pass filter to the mixer, where it is converted to 460 KHz IF. The circuit is based on the well known Lidia direct conversion receiver. So, I guess this would make version 0. Mar 6, 2021 · Congratulations to Charlie Morris ZL2CTM for his first contact with his Simple SSB rig. May 14, 2021 · The N6QW Simple SSB Transceiver Those that have been following my blog for a while, know that I am a fan of Pete Juliano, N6QW, and his MANY transceiver projects. Given our current band conditions and according to the sunspot cycle oracle, she is telling us that the next cycle will be in the 100 range which is a) no better than our current cycle and b) about a third of the numbers of sunspots in Cycle 19 which peaked near 300. This new one has some improvements and modifications: It is much smaller, it is only 1/4 of the size of the This video shows a very simple software defined radio receiver implemented using the GNU Radio Companion. Simple SSB superhet receiver. The received signal, in the 3. The lineup includes: Four 2N3904's, Two 2N3906's, Two J310's, One 2N2219A and One IRF510. A dual-band transceiver with a crisp receiver and a clean SSB signal is described. 5-4. It was designed for the 40m amateur radio band. There are so many cool things in Charlie's video, starting with his mention of having been woken up early (2 am) by the very strong earthquake off New Zealand. Recently on the SolderSmoke blog, there was a post about one of Pete's project being built by group of amateurs belonging to the Vienna Wireless Society in Virginia. Bi-directional SSB transceivers have been quite common in amateur literature. 180MHz (old FT-101 filter). formance direct-conversion receivers that are part of a series of SSB and CW receivers I've been experimenting with. And since there's nothing really to limit what the phasing network has to handle in the receiver, it has to be better than on a simple transmitter. Signal connections are RF, AF and VFO. It started its life as an investigation of the excellent S7C receiver described in EMRFD. Each receiver is engineered for a very specific purpose and is designed from the ground up to perform one task as well as possible. My question is regarding the output frequency of the Si5351, if am not wrong is and sqare output instead of a sine wave no? See full list on dk7ih. The receiver is muted when a companion transmitter removes the May 15, 2024 · SSB receiver The Weaver method of SSB demodulation. Both operate at the 455-kHz IF frequency and will only need loose coupling to SHORTWAVE RECEIVER 10 kHz - 30 MHz (2002) KLIK HIER VOOR DE NEDERLANDSE VERSIE. Mute Control The external mute control system is compatible with that used by the R. Right now I am using this particular receiver for my entertainment, for the shortwave broadcast bands affect the receiver’s performance. A useable shortwave receiver for the reception of one or more amateur bands that can receive SSB, CW and possibly AM. The receiver is tested on 80, 40, 30 and 20 meters but the higher frequency bands can also be received. Classic 40 is a high-dynamic- range, high-fidelity direct-conversion receiver for the 40-meter band. Nov 21, 2021 · He forged ahead, building a novel design that he calls Pete’s Simple Seven SSB Transceiver, or PSSST for short. The demo uses the Universal Software Radio Peripheral (USR Aug 29, 2016 · Centre: Polyphase Network and Tayloe Detector board. The board is intended to be a SSB detector / SSB exciter, i. I have a good feeling that this can become a really great receiver, both for amateur radio bands, or for general shortwave coverage. A more complex example is the bidirectional SSB transceiver. May 28, 2000 · To enable the reception of SSB signals, two simple designs for the beat frequency oscillator (BFO) are also presented (Figs. For example, they are not only far superior to those of a simple feedback receiver. 3a and 3b). It’s a simple regenerative receiver for AM, SSB, CW, FM. Bonus Tracks A 40 Meter Direct Conversion Receiver Project ***** June 11, 2020 . Stage 1. It will also provide total control of the receiver’s gain when the AGC is defeated. Amplifiers are wired in such a way to relays or PiN didoes so Apr 5, 2010 · The simple SSB software defined radio receiver is now functional! Few days ago I wrote about how to upgrade the simple double side band receiver to single side band. Demo of a simple SSB/CW software defined radio receiver implemented using the GNU Radio Companion. Need a simple, fun project - possibly for a Scout Radio Merit Badge? It is easy to listen SSB, even on 18 MHz. . The demo is running using the Universal Software Ra receiver gain with the AGC enabled. This is a slightly improved and simplified version of the receiver. For some reason the GRC generated code lacks the ability to set the AGC parameters. The set will cover all of the HF ham bands, as well as the International Short Wave stations. IF amps are 2N3904. What I saw in the early building stages were not so good results (ie the balanced modulator was crap) -- so I thought this is wasting a lot of time* therefore, why not do it in solid state but make it a Jun 18, 2020 · The CW direct conversion transceiver is the simplest illustration of this principle. The modification was supposed to be very simple and involved changing the band pass filter from using real taps to use complex taps. Currently on 20m. If you don't knock out the sideband with a good phasing network, you get interference from the "audio image". Drake Co. To enable the reception of SSB signals, two simple designs for the beat frequency oscillator (BFO) are also presented (Figs. circuit is relatetively simple:. Stage 2 will be the transmitter. What makes the PSSST so simple is not only its construction, but the low With this very simple receiver, many radio amateur stations can be heard with a wire antenna of 5 meters. So far the SSB exciter configuration hasn't been tested. Homebrew 80m SSB Receiver MC3362 - KendinCos Homebrew 80m Circuits Diagram-Elecpod Simple BFO to make (CW and SSB receiver). It works great on 80m, 40m and 20m as tested by me. Jan 3, 2021 · Hi charlie, thank you for your detailed design, I am interested in build a VFO of an old 80 mts SSB BLU (modified :) ). The Simple SSB Transceiver This project uses only 10 Transistors/FET's to make you heard on the airwaves. The simple shortwave receiver for CW and SSB. It can be adapted to other HF bands as well. Then, having the project on “GO!”, I finished the design. The other side of the equation however shows that simple designs using clever circuits is just that … a compromise. Despite the very simple demodulator circuit, a very useful SBB reception is possible. ywil sjp spfydk pryl cah jyykx hox hquft wld musn
