    N1UL - Dr. Ulrich Rohde

    There are a few famous hams in our ranks and this week I had the pleasure of speaking with Dr. Ulrich Rohde, who is the son of one of the founders of Rohde & Schwarz, one of the world's foremost test and measurement equipment companies. Dr. Rohde was one of the pioneers of SDR and quoted from the DL35SDR page:

    Prof. Dr.-Ing. habil. Ulrich L. Rohde, DJ2LR / N1UL was the first to describe possibilities and perspectives of SDR in a congress lecture at the "Third International Conference on HF Communication Systems and Techniques" in London in February 1985 (classified).

    DJ2LR / N1UL, member of DARC Amateur Radio Club Munich South (C18) is recognized as one of the pioneers of SDR technology 35 years ago. In the 1970s DJ2LR was head of military equipment development at AEG/Telefunken in Ulm, where he was responsible for the construction of the AEG 6861 Manpack.    ​

    We're excited to have received three excellent technical papers from Dr. Rohde, which he emade available for wide distribution on QRZ. We're honored to have him as a QRZ Lifetime member and proud to serve these pages in support of his longtime service to all.

    There are three papers. They are all in PDF format, attached to this article. They include:

    • Test and Measurement for Radio Communication Equipment
    • The Rebirth of HF
    • Using small antenna for portable operations
    We hope you enjoy these great references from Dr. Rohde.

    73, -fred AA7BQ

    Be careful on the 're-birth'.

    Many hams are professionally part of this re-birth of HF, for commercial and defense needs. Hardly a surprise. But heed the warning: re-birth of interest spells future LOSS OF HF amateur radio allocations--IF we do NOT use the bands.

    I have had the privilege of making FT8 contacts with N1UL on six different bands. His knowledge and expertise are “way” above my pay grade. Did I mention “Way” above? HIHI. I never cease to be amazed at the gifts that many people have been blessed with.
    Thank you, Dr. Rohde’s for your hard work and resulting contributions to the world of radio and communications.

    Dr. Rohde's checked into our 6 Meter AM net here in Raleigh, NC a few weeks back and spent some time telling us about his 6 Meter AM operation. Dr. Rohde’s you are truly a marvel and the Raleigh Area 6 Meter AM net would like to thank you for your contributions to the world of radio and communications.

    In my work I have had the opportunity to use Rohde & Swartz equipment, I confirm the great quality and precision of these instruments.
    Thanks dr. Rhode.

    Thanks for the papers, have added to my reading list.

    I was fortunate to work N1UL on 20M FT8 on 2019-12-25 19:09.

    Truly a giant in our midst.

    This didn't sound quite right. A little bit of Googling and reading of Wikipedia indicates that R&S was founded in 1933 and N1UL was born in 1940. But he does have a connection. R&S was founded by Lothar Rohde (and Hermann Schwartz). Lothar Rohde is Ulrich's father.

    Short bio
    Only skimmed them so far, but they do look interesting. I have two of Ulrich Rohde's books on my book shelf and he has contributed several articles to amateur radio publications. He has contributed a lot to amateur radio.
