Components And Links

Components And Links
by Harry Lythall - SM0VPO


I don't normally add "courtesy links", but I that I spend a lot of time searching for datasheets, and these particular links are just too good to refuse:

Datasheet Directory is a site that has been the result of a lot of years of hard work by the author (Jack) to collect many 1000s of datasheets. These he offers for free at The site is also organized by function, which makes it easier to find datasheets for any specific application.

Datasheet Archive Search engine for electronic component datasheets and application notes, at The Datasheet Archive.

There is also site at where you can find loads of datasheets.

Amateur QSL cards

I recently began operating SSB and PSK-31 on HF, but my QSL cards are about 8 years out of date. I was recommended a couple of sites by a friend. They produce reasonable cards at a very reasonable price.
- - The simplest possible way to order QSL cards for very good price - choose your design and fill in the ordering form .
- - Top quality, superb prices, fast delivery and easy ordering. ELLI™'s QSL cards bring you even more confirmed connections.

Component Suppliers is A Swedish company, based in Gotherburg. Baltechno have been repairing RC electronics for nearly 20 years. They have built up a very well equipped work shop and are authorized by, for example, Graupner/JR, Hitec, Thunder Tiger, K.O. Propo, and Kyosho. They repair RC equipment for the whole of Scandinavia and sometimes get repairs from countries like Germany, France, Greece. E-mail . I found them VERY helpful obtaining R/C mechanics. is well worth a visit. They stock those "hard-to-get" RF chips, such as prescalers and synthesizers, etc. They were the answer to my prayers after searching the web for weeks. is a fantastic component supplier in the UK for the RF constructor. On-Line cataligue too! They even have stocks of the TCM3105. I started using them over 30 years ago.

Private links

Please do not ask me for "courtesy links" because the answer is NO. I will only provide rare links that are related to my homepage subject material and only links that are in some way 'special'. If you want a link somewhere then I reccomend you visit UK Amateur Radio quick links or where you will find just about all the Ham radio links I want.

Anyway, here are the 'special' links:
