Heathkit HW8 QRP Transceiver

The HW-8 was the second in a line of direct conversion QRP CW transceivers from the Heathkit stable. The HW-8 was a significant improvement on the HW-7 which was first released in the early 1970s. I bought mine from another ham already built, although I had been strongly considering buying one for some time before then. I almost bought the HW-7 some years before too.


This was a fun rig to use: for a time it was the only transceiver I owned and I worked plenty of stations using it with just simple dipoles. I was not really troubled by the double tuning inherent with DC receivers. Microphony, that can be a real issue with poorly designed DC rigs, was not a noticable issue on mine. The styling of the rig was excellent - simple front panel that was easy to navigate and a plain, simple, dial that was easy to read. Power output was perfectly OK for working around Europe and the occasional DX a bit further. I am sure that had I not bought an FT-7 I would have worked DXCC with it without too much effort.


The lack of a backlight was a pity: OK for portable but a nice to have at home. It would have been better with 10m included: this came later with the HW-9. In my opinion the HW-8 was a nicer looking rig and the neatest of the three.

Like all in the Heathkit HW series, this model has a whole list of modifications available for it on the internet and in magazines and books. Attached are links to just a few of these. Mine was a virgin unit - no mods at all - and I was perfectly happy with it just as it was!
