UPDATE 18 June 2013
LAFAYETTE TELSAT 805B. I have found the solution to the pulsing problem on the evident mostly when on USB or LSB. The cure takes about one and a half hours to sort out, so for a rig previously properly aligned it will cost £36 plus return carriage by Interlink of £14.50. For a rig in needs of a full alignment the cost is £60 plus return carriage of £14.50.

SP1000E SPEECH PROCESSORto increase the sideband power and hence communications effectiveness of SSB and AM transmissions. The unit has a frequency response which enhances the higher voice tones which carry most of the intelligibility. The peak to mean ratio of the transmission is improved by 10dB which has the same effect as increasing the transmit power by 10 times. Boxed Kit £48.00UK, £55.00 EU, £59.00 World. Ready built £66.00 UK, £75.25 EU, £79.25 World. Prices including tracked carriage.
PT1000S PIPTONE Roger Bleep. The unit provides 50mV across a 600 ohm microphone. Tone frequency and amplitude are pre-settable. A relay is included for loudspeaker and PTT switching. PCB size 44 x 25 x 17mm. PCB Kit £9.00 UK, £11.00 EU, £12.00 World. PCB Built £13.25 UK, £15.25 EU, £16.20 World. EU & World tracking £5.50 extra.
KT2000 KAYTONEBleep (a name coined by Spectrum), this unit is the successor to the original Kaytone sold in 1979. End of message morse K particularly useful for weak signal situations. Adjustable pitch, speed, and level. A relay is included for TX and RX switching making it suitable for all rigs. PCB size 58 x 39 x 15mm. PCB Kit £14.25 UK, £16.25 EU, £17.25 World. PCB Built £21.25 UK, £23.25 EU, £24.25 World. EU & World tracking £5.50 extra.
TT2000 TUNETONEBleep. Musical end of message signal with nine individually selectable notes. Adjustable pitch, level, and speed. With relay switching to make it suitable for all commonly available rigs. PCB Kit £15.50 UK, £17.25 EU, £18.25 World. PCB built £24.00 UK, £25.50 EU, £26.50 World. EU & World tracking £5.50 extra.
HG2000 HYGAIN BLEEP A board designed to mimic the sound made by the bleep unit in the Hy Gain 5 multimode rig. Adjustable speed and level. With relay switching to make it suitable for all commonly available rigs. PCB kit £15.00 UK, £17.00 EU, £18.00 World. PCB built £22.00 UK, £24.00 EU, £25.00 World. EU & World tracking £5.50 extra.
NS1000 NOISE SQUELCHa really effective cure for all the annoying background noise produced by FM receivers. Allows reception of weak signals without loss of any except those which would have been unreadable anyway. Particularly useful for homebase use where its performance like that of AM is less annoying. PCB Kit £15.50 UK, £17.50 EU, £18.50 World. PCB built £21.75 UK, £23.75 EU, £24.75 World. EU & World tracking £5.50 extra.
SF10.7 SPECTRA FILTERactive filter incorporating a 2 pole crystal filter to replace the 10.7MHz ceramic first IF filter in early CB radios. The effect is to reduce bleed-over by about 90% and by being active does not cause loss of sensitivity of the rig. PCB size 36x20x17mm. PCB Kit £8.00 UK, £10.00 EU, £11.00 World. PCB built £10.50 UK, £12.25 EU, £13.25 World. EU & world tracking £5.50 extra.
FM455 FREQUENCY MOD-DEMODadds very good quality FM transmission and reception to AM only CB rigs. Receive side connects to the last IF amplifier before the AM detector. The transmit side connects directly to the microphone input and provides processed audio to the varicap diode in the PLL circuit. PCB size 44x39x16mm. PCB kit £13.50 UK, £15.50 EU, £16.50 World. PCB built £18.50 UK, £20.50 EU, £21.50 World. EU & World tracking £5.50 extra.
SP059 SPEECH PROCESSORfor Cybernet multimode rigs. Specially designed to overcome poor quality audio on PTBM059 & PTBM121 chassis. The board picks up the audio drive to the VCO processes it and then feeds an add-on varicap board. PCB size 40x20x15mm. PCB kit £9.50 UK, £11.50 EU, £12.50 World. PCB built £13.00 UK, £15.00 EU, £16.00 World. EU & World tracking £5.50 extra.
VCO27 VCO BLOCK. Replacement for green block in Cybernet multimode rigs PTBM059COX and PTBM121D4X, also allows the rig to accommodate extra channels such as UK81 band. Type VCO27 for CB bands, for conversion of rigs to the 10 metre band useVCO28. Built £7.50 UK, £9.10 EU, £10.10 World untracked.
VCO48 VCO BLOCK. Replacement for silver block in Cybernet multimode rigs using PTBM048AOX chassis. £10.00 UK, £12.00 EU, £13.00 World.
EU and UK add-on boards for FM rigs
SC26L SYNTHESISER CONVERSION to add EU band to UK rigs which use the LC7137 PLL IC. PCB kit £27.50, PCB built £35.50.
SC26A SYNTHESISER CONVERSION to add EU to UK Amstrad rigs which use the LC7136 or LC7137 PLL IC. PCB Kit £27.50, PCB Built £35.50.
SC27L SYNTHESISER CONVERSION to add UK to EU rigs which use the LC7132 PLL IC. PCB Kit £27.50, PCB Built £35.50.
SYNTHESIZER CONVERSION CB to 10FM suitable for UK CB rigs with LC7136/7 or TC9119P PLL ICs. Puts the rig onto 29.31-29.70 MHz. State rig type when ordering. PCB size 64 x 40 x 17mm. Type SC29. PCB Built & aligned £32.50 UK.
