I was lucky enough to find a new display on eBay and very lucky to win it. I have It looks to be complete but I will If it goes bad then the radio is of little use. Once again I was lucky enough to This radio was very difficult to build and many of them ended up at Heathkit. Heathkita Each filter comprises two pi—sections. Relay K552 is connected across the lstolt supply and is used to operate the relay in an external linear amplifier. Transistors Q551 and Q552 form an overvoltage pro— tection circuit for the Transceiver. If the input volt- age should happen to exceed 16 volts DC, diode. D552 conducts and turns on transistor Q552. A series-regulating circuit is formed by transistors Q555, Q556 and diode D555. Transistor Q556 senses the voltage at the emitter of transistor Q555 and ad- justs the voltage drive level at the base of transistor Q555 as the load varies. Diode D555 forms the refer- ence voltage for transistor Q556. Transistor Q553 supplies the drive for transistor Q554, which supplies the bias voltage to the power ampli?er in the transmit mode. The BFO circuit board also interfaces with the controller to generate several DC logic voltages that operate many stages throughout the Transceiver. In the LSB mode, crystal Y801 is selected by diode D808 and connected to the series-tuned circuit formed by capacitor C819, coil L804, and diode D809. Transistor Q814 forms the BFO oscillator which has the required feedback provided by capacitors C811 and C812. Buffer transistor Q818 drives the low-pass ?lter that is formed by capacitors C805. C806, 0807, and coil L801. This filter reduces any harmonic con- tent in the signal produced by the BFO. Crystal Y802 is used during USB operation and operates in the same manner as the LSB circuit.

Diode D812 allows the IF shift voltage to pass during the re ceive mode so diode can operate properly. Diode 0813 and resistor R834 cause the SSB oscillator to re- turn to center during the transmit mode. Diode D814 In the USB mode, the controller circuit turns on trans- istor Q801. Thus turns on transistor Q802, which pro— duces an USB voltage that turns on crystal Y802. This also turns on diode D802 which turns on transistor Q807. During the narrow CW (transmit) mode, the control- ler circuit turns on transistor Q811 via diode D807. In the wide CW (transmit) mode, the controller turns on transistor Q1311 through diode D806. Transistor Q811 also turns on transistor Q809, which provides a 9-volt source for other circuits in the Transceiver. Also during CW operation, transistor Q809 turns on transistor Q806 which keeps transistor Q807 off. Transistor Q807 is only turned on in the USB and LSB modes and turns on transistors Q805 and Q8138. This generates a DC voltage in the transmit mode to operate the SSB centering and other stages. The various circuits on the controller circuit board will now be described in detail. This arrangement produces two pulse trains as the wheel rotates that are in quadrature (they are ap- proximately 90 degrees out of phase) to produce four unique states. One of the shaft encoder outputs is applied to the external interrupt input of the micro— processor. This allows the microprocessor to deter- mine the direction of rotation. When this input goes high, the microprocessor determines whether it should increase or decrease the frequency. It also determines whether or not you are using the fast- tune metallic finger insert in the Main Tuning knob. Schmitt trigger transistors Q703 though Q706 pre- vent false triggering due to vibration. Each of these loops uses a frequency synthe- sizer integrated circuit, which contains programma- ble divide-by-N and reference dividers and a digital phase detector with a lock—detection circuit.

To pro- gram one of these IC's, each of the internal dividers is programmed by applying a 3—bit binary address code (to select one of the seven digit latches) along with a 4-bit binary digit code, and then the strobe input of the particular IC to be programmed is strobed. This process repeats for each of the seven latches within the IC. Page 59. The address and data inputs for each of the three synthesizer IC’s are connected in parallel across this port. Due to the loop select logic, only one of these latches receives the strobe pulse at a time. Since only seven of the eight lines from port 4 are re- quired, three for address and four for data, bit 7 is available to help select between the three 103. One bit can only select between two ICs, however, so a trick must be used. Because there are only seven digit latches in each IC, the latches ignore a binary code of 111 (decimal 7). If integrated circuit U701B is in the cleared state and bit 7 is high, integrated circuit U711B passes the strobe pulse to integrated circuit U712. If integrated circuit U701B is in the set state.Since in- terated circuits U703 and U712 must be reprogram- med each time you make a frequency change, inte- grated circuit U7OIB is normally kept in the cleared state. NOTE: Integrated circuit U705 is reprogram- med oniy when you make a band change (except for the 10-meter band, which is divided into four seg- ments). An external pulse width detection circuit senses this increase. NOTE: Since each lock detection circuit is identical, only the cir— cuit associated with integrated circuit U703 is de- scribed in the next paragraph. When the loop is locked, transistor Q711 is held on, which prevents diode D703 from conducting. If the loop unlocks, the wider pulses at the base of Q711 allow it to turn off long enough for capacitor C731 to charge through resistor R731 and diode D703. When the charge on this capacitor reaches 0.7 volt, transis- tor Q709 turns on.

This applies a low to an input of integrated circuit U708C and takes its output high, which is inverted by integrated circuit U7OBB. Transistor Q709 lights LED D703 to indicate that this loop is unlocked. Two of these are parallel-mode oscillators and are located on the con- troller circuit board. One of these oscillators operates at 8.04 MHz and is made up of transistor Q701, crystal Y701, and the associated components. The other oscillator on this circuit board, formed by transistor Q718, crystal Y702, and the associated components, operates at 10 MHz and operates very similarly to the 8.04 MHz oscillator. The output of buffer transistor Q719 drives the reference divider chain in integrated circuit U705. The original radio was computer controlled with 3 PLL circuits(now DDS) allowing for both keypad and knob tuning of frequency.I made an adapter board to allow the 40pin DIP MC68HC11D3 to plug into the 40 pin DIP socket of the original 6502. This is the Assembly Code I wrote to replace the original Heathkit 6502 CPU. I did not have access to the Heathkit source code, I just reversed engineered it.Original design output was too low causing distortion. 3) Crystal controlled BFO SSB selection replaced by computer controlled 32bit DDS AD9850 IF generator. 4) Audio input selection replaced by self contained SSM2019 full spectrum audio preamp with automatic line level limiter. The preamp directly feeds the balanced modulator and does not allow overdriven audio input. 5) Reconfigured the IF boards 2.4khz crystal 8.830mhz IF filter with a front panel selectable 4.0khz or 2.4khz or 6.0khz 8.830mhz IF filter board.I made an adapter board to allow the MC68HC11D3 to plug into the 6502 socket.

The Heathkit HW-5400 HF SSB Transceiver covers the high frequency bands from 3.5 to 29.7 MHz. This microprocessor based transceiver is entirely solid state and delivers 100 watts (80 watts on 10 meters). Broadbanded circuits eliminate the need to “tune” circuits within a band. Just turn the bandswitch and select the desired frequency. A crystal controlled timebase provides high accuracy on all bands without a calibrator. Microprocessor control of entire operation. Optical tuning encoder for smooth, linkage-free tuning with no backlash. Memory on each band Two sideband filters (one optional). Adjustable passband shift to help reduce adjacent frequency interference. A VSWR protected power amplifier Internal diagnostic capability.

All assembly manuals, large fold outs, schematics and updates are included. I verified all printed circuit boards are there and in good shape. The packing looks like it has not been disturbed. The power supply is not included, (HWA-5400-1). This unit can be powered from any 13.8VDC, 20AMP supply. The high current connectors are supplied in the kit for building your own cable assembly that plugs into the back of the HW-5400.
