When connecting PTT and GND, presto, the radio keys a solid CW 100W carrier with sidetone. There are 2 of the 6 actual pins that are controlling lines for PTT and GND. There is another use of ACC Jack: it can be used to key amplifiers or switch Transmit/Receive antennas, if you have separate receiving antenna like 160M Beverage antenna. FT-450 FT-600 FT-817 FT-857 FT-897 FT-900 FT-991 FT-991A VX-2100/2200: Notes Speaker audio and power are available on some models. Eureka moment: the 6 pin (mouse port, dont know the actual name) DATA jack on the yaesu FT-857/897 (and maybe 817 too) is a 6 pin keyboard/mouse styled plug. I used old radio components I had in my junk box, transistor can be replaced with any n-p-n all purpose transistor like 2N2222, diode replaced with 1N4148 or similar. I have been using this thing for about 10 years and battery still going strong. If you have a RIGblaster Plus or Pro and wish to operate pure FSK instead of AFSK with your radio in the RTTY mode you must configure and connect the RIGblaster's keying output to.

When none of buttons are pushed no power is drawn from battery thanks to diode D1. How to set up a Yaesu FT-991 for FT-8 using the WSJT-X software Hi there, I was asked to produce a video showing how you set up a Yaesu FT-991 for FT-8 using WSJT-X. The battery is 12v micro battery used for remote doorbells and it sells in every supermarket. RTTY is spot on if you set the RTTY sweet spot to 2210 in the Configure->Misc->Sweet Spot Tab of Fldigi. When S2 is pressed negative ALC voltage is applied but keying because of C3 is delayed, finally transistor T1 opens and through diode shortens center ring to the ground. a big push was made to get new RTTY operators set up and on the air.

Serial or parallel port keying may work fine, particularly with faster computers, but using Winkeyer can enable you to get by with a slower machine or run other programs in conjunction with N1MM Logger+. I tried to came up with schematic that would prevent this behavior. N1MM Logger was one of the first Windows logging program to support Winkeyer, and it has become a favorite CW solution for N1MM Logger+ users. So it seems like a simple task: ground the ring and give some negative voltage (0V to -4V) and we can tune antenna tuner or amplifier with lower power (this is especially useful with automatic antenna tuners because they will not tune if full power is applied), if we ground just the ring we will tune with full power.Īll this is not entirely true, when we connect ground and negative voltage at the same time we get short spike at which transmitter gives out full 100W and then drops to preset value, this happens because of delays in ALC circuits.

The “TX Request” connection, when shorted to the ground, puts the FT-857D into the transmit mode, and sends out a steady CW carrier, for linear amplifier or manual antenna tuner adjustment. This 3.5-mm 3-pin jack accepts external ALC (Automatic Level Control) voltage from a linear amplifier on the tip connection, and accepts a “Transmit Request” command on the ring connection. FT-857/897 Transceiver has ACC jack which can be used for keying the transmitter ( of FT-857 manual).
