Hi Harry,
I monitor this forum almost daily. I write here if I have some thought to add only.

Hi Ivan,
So nice to hear from you again :-)

Thank you very much for the information. It was a very interesting site, and there are loads of fixed inductors that are also of particular interest. When I have finished my oscilloscope project I will place an order with them for a load of components.

A couple of years ago I was given a box of 100s of assorted cans. Nothing useable pre-wound, but they are very good for rewinding. But for the 3-band pocket SSB receiver I really want to use ready-made coils. Thanks again for the information.

Very best regards from Harry

Hi, various types of coils suitable for rewinding are here:
HADEX
Fixed inductors show first, go down through the pages.
Prices are in CZK, 1 EUR=cca 26 CZK

Update

I received my 455kHz IF cans; had them delivered to work while I was away. The product code ACS1667 does NOT include the MW oscillator coil; just a set of four IF cans.

But BG-micro did send me extra YELLOW cans FOC, since there are two variants; one with capacitor on the primary and one can with the capacitor on the secondary winding. So I received four cans in each set Smile

I have asked BG-micro if they sell the MW oscillator coil, awaiting a reply. I will update this post with their reply.

I know the MW band is dead, but the idea was to make a 1MHz tunable IF (1MHz to 2MHz with osc = low) for SSB and cover 160m directly, 80m and 20m using a simple converter.

Hello again,
I have been searching the web and found that www.bgmicro.com (USA) offer a set of four IF transformers for US$1.80 each. They have about 15,000 sets in stock.

They are NOT the yellow/yellow/black sets you often find, but the full red/yellow/white/black set of four.

They will dispatch worldwide :-)
