Featured key

Heathkit HD-1410 electronic keyer

The Heathkit HD-1410 electronic keyer was a popular addition to the famous Heathkit SB line of equipment in the 1970s.

This iambic keyer, with built-in paddles, has a speed range of 10-60wpm and operates from 115V AC, 240V AC or 12V DC. The sidetone frequency is adjustable. There is an internal speaker and a rear-panel headphone jack, and receiver audio can be fed to the speaker or headphones via a rear-panel jack.

Heathkit very thoughtfully provided a rear-panel connection for an external straight key or bug, so this unit would also make an excellent code practice oscillator while you saved up for the rest of your SB Line station. 🙂

* If you have an interesting key for this feature, please send a nice clear photo and a few words describing it.

Dunedin dominant. In the first decades of the 20th Century, Otago province, and Dunedin in particular, played host to a number of achievements that advanced the science of radio. And today, we have Dunedin dominating our membership list, with three Participating Members of NZ Net: ZL4GW, ZL4KX and ZL4DY.

Speaking of amateur radio achievements, I will be giving a talk on that topic to an Auckland historical group in about a week. I am looking for examples of how NZ radio amateurs have helped develop new technologies or have provided public service – particularly in the 21st Century. If you know of any interesting examples, I’d appreciate hearing from you.

Test runs underway. Until the end of this month, we’re running 15wpm sessions of NZ Net at 8.30pm Monday and Thursday on 3535.0 kHz. On weekends, we have sessions at regular speed at 9.00pm on 7035 kHz. For details, see NZ Net News 133.

The VKCW Net would love to have you check in each Wednesday at 0603Z on 14.049 MHz. The net has a new webpage too.

Straight Key Night is this Sunday, from 8pm to 9pm on 80 metres. Get details.

Poetry corner

He who with faultless Morse, impatiently,
Has oft un-nerved the bloke who’s QSD,
May reap the hasty harvest he has sown,
By having nervous trouble with his own.

– ‘Awarua’
(NZ Post Office Radio Information Bulletin 3, Apr 1959)
