I don’t really understand the question. What do you really need to know ?

How much head space do you need in the loft? Thanks, M0IDS.

So much of why we like radios is subjective. How they sound and look for instance. But in every imperical way, Elecraft outperforms ten tec. I had an Omni D series B and the original Orion. I think the only radio that comes close but no cigar to Elecraft is the Omni VI. Best receiver they made. What were Ten secs good at? Best QSK of their time Some of the first solid state rigs Great CW Rig What were their deficits? Noisy synthesizers Stability issues AGC pumping Marginal final amp protection Let's face it, what makes a great radio is a great receiver. Comparing internal speakers is useless. And the K3 is really a better comparison, but the K2 is a better receiver as well. Elecraft has Better blocking dynamic range from down conversion design Every bit as good QSK with PIN diodes, designed, like ten tec, by CW enthusiasts More stable Quieter synth Lower IMD on the audio amp And the Yaesu DX10 and DX101D are even better than that. They will continue to receive a signal being blasted by a strong adjacent signal long after the Ten Tec RX melts. That's why Sherwood rates by BDR. It is a game changer to have a BDR radio. I would like to own a Ten Tec again for nostalgia, but not for performance. They are just nice radios and very simple to operate. Direct sampling is the future and is already passing superhet design in every measure.

I don't think it's a fair comparison. 10 W QRP to 100 W QTH rig. The TT is twice the size, and it is not twice the rig IMO. Both are good radios though. Makes me happy I have one of them.

Ten Tec was just better than the operators ...the gear is so incredible, it took decades for anything to duplicate it's performance. Today you can buy an FT-991 which is a decent rival of the Orion II, smaller almost as cheap to buy. But hey..it took 25 years.

Is it just me or do Austers always look worse for having a flat four in the front?

I noticed you have the audio peak filter on at SSB. That gives the strange audio. At CW a great transceiver. I have one here and use it a lot on CW. 73 Durk PA3BYW

Just love Ten Tec.. I had the Paragon, Corsair and a fantastic Omni6plus.... Like all rigs they have their issues.. But theyre something a little bit different to the usual jap black boxes..

Excellent work Well.done!!

David I've worked Brazil ssb on 10m 100w with my bantenna bottom of my garden , very pleased with it.

I often switch the K2 preamp off, as well as using the RF Gain. Another thing would be to hear both radios through the same loudspeaker. I think the best option is to have both radios!

Interesting to see the bungee tool in use. How many people required to do the job safely? Working by myself I don’t believe I’d have been able to use that method safely, which is why I used the hydraulic engine hoist.

👍Corsair 2 is still a formidable CW rig. Break in on CW still puts some modern rigs to shame. Sacrilege perhaps but I modified mine with a DDS VFO kit to make it more stable and provide dual VFOs for split. With no internal fans and rated at 100W/100% duty cycle, it can be more pleasant to operate than some modern rigs.

I am still using my Corsair that I bought new I the early '80's. I had it tuned up and aligned by the Radiosmith in St. Petersburg FL. It is better than new with the exception of the 500 hz CW filter. I will replace that with an InRad. 73 de WS4K

This video reminded my why I love Ten-Tec radios on CW. Just fantastic. I’ll have to hook up my Omni D tomorrow now. Thanks for the video!

Hi, from the one pole to the other pole is it 6m in length? So then the wire is twice that length with it coming back on itself. Thanks

Great CW wireless David… glad I kept one 😂

Mine is permanent at home qth mounted at about 5' above ground , FT991A tunes perfectly even on 50Mhz , 5/9 into Brazil on 10 the other day , Ukraine, Finland, Bulgaria, Croatia, The States all bands work very well. Very pleased with mine. M5LLT

I've got the sleevetenna from yourself and it works great got into Hong Kong the other day at ground level in built up housing estate very low noise and the signals just pop I was also qrp on 10w

dear david i wonder if you can tell me is the wire that is built into the nylon sleeve helically wound or just a straight single wire ? i fully understand if you do not want to say best regards.alan. 73

Well I wasn't expecting that......

Easy I've mine set up in trees in the garden on telescopic pole , works great no issue with weather or rain etc

can you please tell me the length of your antenna sleeve ? and do you use a 49-1 unun.

can you please tell me is the unun you use is a 49-1 ? and how long is the sleeve antenna ?.

David very interesting, are there any benefit to adding a counterpoise or ground radial for a weekend contest?

Just bought to use qrp with ic 705 and also ah705 used today got a few copies on 20mtrs running 5 watts …. So far so good 👍

Great video David, would love to see a comparison video like this for the Bantenna :-)

Hi David, I thought that it was a good time to give you an update on how I have got on with the 100W version of your 80-10m ended antenna that I bought from you in 2020. I moved to a bungalow in a village on the Lizard after living in a loft conversion in Falmouth, with no ability to use outdoor aerials. I was convinced that an end-fed half-wave dipole was the way to go, in my new small garden and saw this video of your offering and decided to buy one. Well, I have been using it in an inverted-L configuration, with the vertical part supported with a DX Commander fibreglass pole and the horizontal section supported by two poles (one in the middle of the garden, now with 4 m vertical on top) and one at the end of the garden, both fitted with marine pully blocks so I can lower and raise the aerial easily. Your aerial has been a great success and I have made contacts on many bands, including four in Australia (last year and Friday, 21 January this year). I have good success on 80, 40, 20, 17, 15 and 10 metres with it and the only issue I found was a tuning one on 80 m; Using an antenna analyser, I found that I could either optimize the length after the loading coil to cover the cw (lower) portion of the band, or the upper (LSB) portion, but not both. Well, I made a simple fix using a couple of "chocolate blocks" - I have a red wire that I can connect between them for upper 80 m portion, or black wire for CW portion; it might not be very elegant, but it works well! Anyway, even though your antenna was really designed more for portable use and I have had to repair it a couple of times (we get occasional very strong winds here - 50 mph plus), it has given me excellent service, so a big thank you! My friend G4SEN recorded my last Australian contact, so I have posted a video that he made of it (and also linked it on my QRZ page). You might like to watch it here: ruclips.net/video/5fj6OYPfiag/видео.html Thanks again and kind regards, Richard G4WKW.

nice to hear you. Are your bantenna in stock now?? 73 qro HB9GUR

Good video

G90 ATU CAN TUNE A WET PIECE OF STRING :)

Hi David. Interesting point about having the ignition on without the engine running. I know in the good old days it wasn't recommended for petrol cars because if the points happened to be closed you could burn out the coil. No idea about modern cars with electronic ignition though. I would have thought a diesel would be OK, but perhaps someone with knowledge of such things could enlighten us? 73

The set-up works very well David. Very impressed with the G90, seems a very good choice for portable operation.

This is funny , and enjoyable. And a testament to the quality of antenna tuner in the radio . Glad to see you all enjoying experimenting, most folks forget , that’s what this hobby is all about

You can alway sell a magic antenna to an uneducated box operator. 9:1 unun & a piece of wire does exactly the same thing. As the old saying goes, "A fool & his money are soon parted !" 2 Supermarket trolleys will load as a dipole & only cost £1 each so I'm going into business. For sale NVIS cage dipole £1000 (Supply own coax & ATU) Full system £2000 😂

Will this be the answer to my HF woes?

Tuning Is One Thing, Real World Use is Another. U Can Tune A Prison Window Bar :D I WOnder What is The EXACT measurements Of That Antenna? I Think It Got A Lot Of Noise Bcuz I Tried Similar Thing One Day And Noise Was CRAZY !!

Amazing Chris. Thanks for the comment

Hi David , hope your keeping well, I love my sleeve antenna! I use mine at permanent home qth, it's just strapped to the pole for the wife's washing line, about 6ft at the base, I've worked all over the world on mine with just 100w from my 7300, internal tuner handles it nicely, my first contact when I installed the antenna was island of Bermuda on 40m ssb, so it works fine. Chris M1trc

This is my mcHF souruous signal generation! Go to about 14 seconds in and see the party...its not the pin diodes I think (c78 removed, spurii still present).

Just like putting your socks on. whats so hard LOL

Looking forwards to getting the package

Love my bantenna, great solution for my back garden.

VP9NR is Bermuda not Barbados, doh it’s been a long day 👍👍😘 Chris M1TRC

Morning david, hope you’re doing ok, I love my sleeve antenna, I use it from home as my permanent antenna, it’s mounted on the pole for the wife’s washing line, so it’s not very high, I’m working the world with mine on ssb, my first contact with the antenna last week was VP9NR down in Barbados, I’m just using my 7300 and 100w, The internal tuner can tune on all bands Many thanks Chris M1TRC

I would be willing to test one out mate

It seems like you need record not from speaker but directly from line output. Xiegu has small speaker and that mighth be a reason.

If you fancy buying one at a very low price for testing please email me either via bantenn.co.uk or info@bantenna.co.uk

I’d test one for you

This is really interesting, David, could be great news for people like me with limited space for antennas - I wonder if the Loftenna would get on with the built-in atu in the Yaesu FT-450D? Chris
