WSE surplus.(Weak Signal Equipment) A joint effort by SM5BSZ Leif and SM7UFW Niklas.
(Dec 17 2011)
WSE was previously a part of Antennspecialisten, a company that the two of us formed in 1999. It was part of our marketing to make the company known during its early years.

Niklas has the responsibility for Logistics and sales. Send all orders to him as well as any questions you may have on delivery times, availability etc. You can reach Niklas Here:

The WSE converters have been designed by Leif. If something is unclear about the technical specifications you can reach Leif here:


The WSE project is closed but there is some left-over. We ordered 50 PCBs from our subcontractor, but as it turns out they ordered 100 boards of RX10700 and RX70. Now we have unmounted surplus boards. There are also a couple of assembled and tested units as well as untested and failed boards.

We hereby offer 7 WSE surplus packages that would allow the production in part of WSE systems by anyone interested. The packages are slightly different. We offer them at a price of SEK 5000 per package.



- The price includes shipment with tracking number and insurance.
- For private persons within EU we request prepayment to our bank account. 25% VAT is added to the price.
- We invoice VAT registrered companies within EU, terms of payment 30 days.
- Outside EU we request prepayment to our bank account. VAT is not added.

We send the WSE surplus packages to radio amateurs with an invoice to be paid within 30 days. You may, if you so desire, return the package untampered to us within 30 days. We will then only invoice you for the freight cost. You have to pay the return freight yourself.



The PCBs, a dozen or more in each kit will allow building various experimental units of your own. If you have a working WSE system it could be handy to have suitable boxes for the PCBs. Below is quantity and a description of what is in each surplus package. (Packages 1,4 and 10 are already gone)

In each component package there is also 10% of the left-over from production of passive components in the form of components with cut and formed legs to fit the PCB holes. Those components, R, L and C are different in each surplus package. On the average you can expect to find a little less than 10% of the different passive components used in the WSE units in quantities from 1 to 100. Standard inductors only, no toroids and no RM6 cores.
