Ordering, Design and Support

Ordering and Prices

The easiest way to order is by using Paypal. Just enter the name of wanted product, or refer to any e mail discussion, and its price in the box below. Their software is set to automatically add GBP 5 to cover UK post (first class) and packing.

 

Enter product wanted & price

 

For European orders please increase the price by 2 GBP for the extra air mail costs, or 4 GBP for the rest of the world. The Paypal payment should be automatically directed to Walford Electronics Ltd. at electronics@walfords.net

You may alternatively pay by cheque or sterling bankers order (drawn on a UK registered bank), or British postal order, please add 5 GBP to the cost for the UK postage and packing. Should a parcel be lost in the post, please tell me because Royal Mail will only consider claims from the sender and then only to about 20 unless extra is paid for insurance! Cheques should be made payable to Walford Electronics Ltd. and sent to the address below. All prices are in GBP - even if your browser shows a strange symbol! If in doubt, contact me in advance by e mail. Value Added Tax is not charged and so cannot be deducted for overseas orders. We reserve the right to alter specifications and prices in the interest of improving our products. Goods supplied remain the property of Walford Electronics Ltd. until payment is complete. 


Hot Iron and The Construction Club

Hot Iron is a quarterly newsletter about radio related topics sent to all members of The Construction Club. After 100 issues spread over 25 years, it needs a new editor and Peter Thornton G6NGR has kindly agreed to take on that challenge! He will be compiling future issues and maintaining the membership records. He will love to have any suggestions for topics and publishable material on any radio related subject, so please contact him at equieng@gmail.com If you wish to be added to the membership list (or even deleted!), please let him or me (Tim G3PCJ) electronics@walfords.net know! Members receive the quarterly newsletter Hot Iron with articles on circuits for amateur radio receivers, transmitters, test gear, antennae, construction methods, new kit developments, and feedback on builders experiences. Articles, notes, experiences, questions, hints and tips from any person building radio related projects are especially welcome. Peter or I will gladly attempt to answer member's questions. To keep it interesting your contributions are essential! I will continue to contribute articles about essentially analogue radio design projects, and my kits; so if you are purchasing a kit, do consider joining the Club so that you can get the benefit of other people's experiences. Hot Iron does not have advertisements and is usually equivalent to about a dozen or more sides of A4. From Sept 2015 it has been distributed electronically in pdf file format attached to an e mail. Membership and copies of future Hot Irons are free to all who have told their e address to Peter equieng@gmail.com - that is all you need to do!

Group Construction Projects

If the numbers of kits wanted are reasonable I may be able to offer a discount when ordered in bulk. My stocks of individual kits are usually small so advance warning for quantity is essential and it is generally best for the course organiser or Club to make such orders. I also suggest that course instructors should emphasize to candidates, especially for less experienced people, the value and thrill obtained from using the built item on air afterwards, instead of just choosing the cheapest that will get you through some exam! Hence I would always recommend a receiver in preference to a simple CW transmitter that is unlikely to be ever used with an unknown brand X receiver! Please do consult me before ordering items for such projects - electronics@walfords.net

Design philosophy

My objective is to provide kits which provide good value for whatever you decide to spend; consequently I put my design effort into the circuitry, and its cost reduction, because most builders will leave the circuit unchanged but they are often very happy to adapt the mechanical aspects themselves. All kits contain brand new quality components. Like much of life, you get what you pay for so don't expect phenomenal performance from a simple rig! Much effort goes into avoiding parts whose cost would be excessive compared to others in that particular kit - leading eventually to a well balanced design. Another important objective with the more advanced kits, is to provide scope for the builder to customize it. The instructions provided with each kit are extensive and detail the recommended build sequence, with suggested tests after each stage so that confidence grows as the project is built. Part numbers are not printed on the PCB, but for the more complex kits, a unique grid reference system is used to help you locate individual part positions. These kits are not 'build it by numbers' projects and do require the builder to follow the build sequence carefully and to appreciate what should be happening at each stage.

The design work tries to ensure that each kit can be built and tested easily, and will work reliably despite the tolerances on part values and 'disturbances' due to supply or temperature variations.  Several models of each kit are built before they are generally released so that there is a high confidence that, if the instructions are properly followed, it will work as intended - but see below about support!

All kits contain the full set of parts required to build the rig in the basic 'open' or unboxed style, this includes all controls, knobs, sockets (and matching plugs if you are unlikely to have them) together with rubber feet. The simpler kits are built in a 'flat' format where the controls are mounted directly onto the main circuit PCB. For others, either a small etched front panel is included for the small upright format, or an extra single sided un-etched PCB (with strengthening braces) is included as a simple front panel which can be attached to the main board. This open style of construction is fine for bench use and gives good ventilation for improved reliability/stability; it also allows access to both sides of the PCB for building/testing. If you wish, the rigs can be easily installed in conventional boxes which is essential for mobile or portable work. In general, my advice is to build the rig in its simplest form first and, after experience using it, then decide what extra controls you want and box accordingly. Quite often, the presets - or the special 'shafted' presets used in simple rigs - can be changed to conventional front panel pots if you want better facilities. This approach gives the least initial cost but allows enhancements when wanted. The photo below shows the Spaxton and Ford after some tests in Jul 2018!

Support

The use of building by stages, with tests after each section, helps to minimise problems; however if you do get stuck, you can always contact me for advice by phone, letter, or e mail. If this fails to eventually get it working, I am quite happy by arrangement to have the kit back for investigation/repair. If it turns out to be my fault through poor design or faulty parts, then I don't charge; however if its a proven design and somewhere the builder has gone wrong, then I make a modest charge based on the time taken to fix it with postage and part costs extra. Whenever you seek advice, or return a rig, please provide as much detailed information as possible on the problem. If you do damage parts, spares are readily available for most rigs but be aware that small orders tend to be expensive!
