New ! The X-Lock 2.0 VFO Stabiliser Now with adjustable post tuning delay!		The X-Lock locks a VFO to a crystal source to provide drift free operation. This designs takes a fresh approach to the "Huff-Puff" Frequency Locked Loop technique by using a processor to measure frequency and compute correction signals. The X-Lock employs a 100mSec count period to produce 10Hz "lock points" against which the host VFO will be held. Dual regulators are used to supply the digital and analogue sections of the circuit which in turn are optically coupled to produce an exceptionally clean control voltage. The X-Lock will accept input signals from a few kHz up to 50MHz to provide up over 6 volts of control range. Features include auto lock/unlock during tuning, RIT detection and fast re-lock, power on reset auto centring, and a dual coloured LED to indicate lock and input states. An adjustable delay of 1 to 15 seconds is applied to halt the correction process once a tuning change has been detected. This feature greatly enhances slow, fine tuning adjustments on the host VFO. This new version features an improved RF input stage and connectors to remote the Status LED.

C-1 Controller Source Code We've now posted the C-1 Source Code on the downloads page of our website. This provides T-1 users with full access to the code for long term maintenance of their T-1 and the opportunity to customise or develop the code for specific applications. The downloads page is reached by selecting the resources tab on the menu bar.

*Last Update: Friday, 17 July 2009*
*NEW KIT* It's here at last! The T-2 SSB sub System, a complete SSB transceiver core on a single PCB. Add a local oscillator, preselector, PA and sundry parts to get on the air - anywhere from 10kHz to 400MHz!

The T-2 is a single conversion IF system with a TUF-3 double balanced mixer front end. An 11.0592MHz IF filter, dual cascode IF systems, low noise audio stages and robust product detector/modulator together with an effective full wave audio AGC make the T-2 a highly versatile and adaptable module. With the wide frequency range of the TUF-3 front end and the T-2's compact size, (130mm x 75mm x 25mm) this kit will find applications in many transceiver and receiver applications, fixed or portable. Also, through the use of standard, readily available components, the T-2 will be maintainable for many years to come! An ideal "core" for that next SSB project! Visit the T-2 kit page to find out more.

TS520 Gets the X-Lock Treatment! Australian Amateur Bob Mutton, VK2ZRM is the proud owner of an immaculate TS520 with matching external VFO520. Whilst Bob, like many aficionados of older equipment, enjoys the challenges of "tuning up" his transceiver on a set frequency, he is less than enthusiastic about the drift that follows! Bob turned to the X-Lock as a possible solution to curing drift in the TS520 external and internal VFOs. Read about how he installed the X-Lock and the results he was rewarded with here; TS520 X-Lock

The Microcode version 1.4 The Microcode. A compact Morse Code reader that won't break into a sweat when you do! This new kit is a popular choice for both newcomers and experts of Morse Code. Reliable decoding from 10wpm to over 40wpm with an internal microphone or line inputs. A key input is provided to allow the Microcode to be used as a training aid.
		A sensitive integral microphone combined with a tunable bandpass active filter allow the Microcode to operate effectively by being placed near to a receiver's loudspeaker. Alternatively, a line input allows direct connection to the audio output from a receiver. A robust PLL detector combined with digital filtering of the detected signal produce excellent performance, even with weak or fading signals. Two front panel buttons allow the Microcode to be configured at any time during operation. A menu system allows the input source, backlight brightness and display format to be changed easily and quickly. Direct connection of a Morse key is also supported making the Microcode a useful tool for training and skill development. See the Microcode page in our kits section for more details.
New Software Version, - In this latest software version we've employed improved digital filtering to offer enhanced performance in noise and at higher speeds. In this latest version the PLL "anti-chatter" components are not required. Follow this link to go directly to the Microcode Support Page to find out more.

Minicounter version 3.1 Our most popular kit goes from strength to strength! In this latest major re-write of the Minicounter software, we've introduced configuration groups to simplify operation and added new display formats in GHz or MHz to support use with UHF/SHF prescalers.
The 6 Configuration Groups each comprise of a user programmable IF Offset with a 10Hz resolution, frequency multiplier 1 to 255, Radio or Counter mode display modes and GHz/MHz display formats. The new Configuration Group features make it easier than ever to personalise the Minicounter to your specific application, whether that's for operation of a piece of test equipment or as a frequency display for receiver or transceiver. Enhanced features, superb quality and tremendous value! Visit the Minicounter page for more information. Attention 3.0 owners! A bug in the kHz/MHz label display is fixed in version 3.1. Send us your PIC for a free upgrade.
