SSB QRP kits…and a new SDR kit

MKARS80 from UK

A posting to QRP-L on a QRP kit for SSB yesterday generated quite a few emails so rather than answer each individually, here are a few links I’ve been collecting.

Of those listed, I’ve only built one – the MKARS80. Actually, I built two of those particular kits and highly recommend them to anyone wanting to build a kit for 75m phone.

It was a joy to use and, despite having built a number of CW kits, it was a true delight to apply power to the finished kit and hear actual voices coming from the speaker, up and down the band, with beautiful clarity.

I’m also pleased to learn of a new SDR kit from the same group – the Hunter SDR Receiver/Panadapter. Hmmm – I like that panadapter part…

The others I can’t speak of but am interested in the Panda ($73) and the QROlle.

Here’s my growing list in no particular order. Most have a Yahoo Group associated with them. When perusing, don’t forget to pay attention to freq coverage. Some of the Chinese models have very limited bandwidth for the price they’re asking.

QROlle II from Sweden


BY-101A (China) – a 15, 20, 40 and 80m; 15 watts, SSB/CW. Looks great – check out the photos.

Panda (China) and a possible US source here. I emailed Sean KA7MWL yesterday to inquire about availability but no answer yet. I’ll post his answer as a “Comment” if/when I receive one…

BitX (India) – these are periodically available via eBay in full & partial kits.

KN-Q7A (China) – 40m, 10 watts

YouKits (China) – 2, 4 and 6-band SSB kits, among others.


BY-101A from China

MMR-40 (USA) – a KD1JV-designed 40m CW/SSB kit, 6 watts

Juma TRX2 (Finland) – 10-80 meters, 10 watts, SSB/CW

QROlle II (Sweden) – 17 to 160m, SSB/CW, 10 watts. I like it – where’s my VISA card…! Also a 20/80m SSB kit at the same link.

Speaky (Germany) – a 5-band, 10 watt SSB/CW kit

    Good afternoon John, great post with the links I checked out the QROIIe from Sweden but the SMD’s are just not something I am ready for yet. I did check out their Youtube video on how to solder the SMD’s and it’s just not for me yet. The BY-101 looks interesting but again the SMD’s!!

    Adam BD6CR/4 emailed me to inform of a 40m SSB kit from France – Le Projet Forty and that
    1. BY-101A looks great, but it was never released due to technical problems.
    2. PANDA kit should have been superceded by other designs like PANDA2 by BD6RA, shown here:
    Panda 2

    Thanks for the info Adam.

    No answer from Sweden on availability on the QROlle II nor from KA7MWL on the Panda.

    Have a lookm at the OzQRP kits – I’m currently building the Mk1 40 Metre version. Source most components locally – even though the best LCD screen is the one they show – a week from Oz to the UK!
    Have done the MKARS80 with mods – excellent kit!
