QRP radios

I continue to be surprised by how few affordable QRP radios are on the market. The FT817ND continues to be the favourite, but recent exchange rate changes have not been matched by decent falls in the UK retail prices. I think we are still being ripped off by dealers in the UK. The IC703 is no longer made and the KX3 from Elecraft is very expensive over here. There are a few lower cost Chinese HF radios appearing. Overall, there remains little choice in QRP transceivers at sensible prices. I am sure the KX3 is a very good radio but for the same price I can buy 2 FT817 transceivers, and these are all mode and to 70cms.

A multi-band, all mode, 5-10W radio would be a killer in this age where people take lots of holidays and are on the move frequently. I still fail to understand why the big Japanese manufacturerers have not got a raft of low cost units on the market. It seems a gold mine opportunity is being wasted. Maybe I have misread the market?

I know if there was a new, attractively featured, QRP transceiver on the market now at a sensible price I’d be in the line to buy. I am sure very many others would be too.

My Latest Contraption, a QRP portable, all in one, seat & table, etc!

I added a bungee cord on each end to prevent damage from the radio accidentally falling off the table.

My Latest Contraption, A QRP Radio, Portable Table and Chair 11-12-2014 1-22-32 PM 2448x3264

All in one, QRP seat, table,  umbrella and antenna anchor! The bottle on the table is bug spray! LOL

 

Kx3 Radio In Operation on the Table  11-12-2014 1-25-015

The table is a cutting board attached to the existing shelf.

The cutting board is bigger than the existing shelf, so I have more room for logging and a sturdy place to attach the antenna!

A bungee cord takes up the slack from the antenna in the wind. In a real world test, I found that one radial is all I need.

I tried an experiment, adding two, then four radials. There was no detectable change in signal level by ear on or the S meter.

One radial did the trick, and 4 radials didn’t improve the signal at all.

 

Me, In The Drivers Seat of My Portable Table & Chair Set Up 11-12-2014 1-35-43 PM 2168x1870

Note the guy ropes. This is to hold the chair in place. The golf umbrella is stuffed into  a piece of PVC pipe.

The PVC pipe is tied to the chair with cable ties.

Wind and the antenna pulling on the table would easily turn the chair over.

Satisfaction, with My Latest Contraption

Satisfaction! I can’t wait for the next ham radio outing with my QRP buddies.

NAQCC Transitions

Big changes this month at the North American QRP CW Club (NAQCC).

Paul Huff, N8XMS of Livonia, Michigan becomes the new club President. He’s takes the reins from founder Thomas Mitchell, WY3H who recently retired the post. Meanwhile, John Smithson, N8ZYA of Charleston, West Virginia has assumed the Vice President role from the other club founder, John Shannon, K3WWP – who also retired his position.

Launched in 2004, the NAQCC promotes QRP and CW operation through numerous on-air activities. With more than 7,000 world-wide members, the club is very popular and continues to enjoy steady growth. Membership remains free and you can dive as deeply into the action as you care to go, without running out of interesting things to do and goals to achieve.

The monthly club newsletter keeps members informed, educated and entertained and has become one of the premier ham radio club publications available online.

Congratulations to Paul and John as they lead the NAQCC into the next decade of low-power radio fun and adventure!

Almost QRP/QRP contact

My drive to get our snows on....just in time!
Relaxing at the radio with some tea
Have to go into work on Sunday so I wanted to spend some relaxing time at the radio this afternoon and see what was up on the bands. I started out on 17m and it did have some DX on there but it faded very fast. I then received a call from our veterinary that our cats food was in for pickup so it was off to get that. When I returned it seemed that 17m things were just not happening. I jumped down to 20m and came across KB3RUN/QRP calling CQ I came back to him and he did hear me BUT this nasty QRN came over the radio and wiped out his signal all together. It seems to be a plasma TV that is in the area somewhere and by the time I filtered it out KB3RUN/QRP was gone. I did send an email just to let him know I did not forget about him. Most times on my contacts and almost contacts I send an email to thank the op for the contact.

Genesis Q5 1W QRP kit from Australia

http://genesisradio.com.au/Q5/q5_1.jpg

A trawl of the internet earlier found this kit, a 1W QRP transmitter for any band from 3.5MHz to 14MHz. It is available for S19.95 (US Dollars) + S9 (US Dollars) shipped anywhere worldwide. That seems pretty good value. Also on the website are SDR transceivers.

I last showed this particular kit on my blog 5 years ago.

See http://www.genesisradio.com.au/Q5/ for more details including how to order the various kits. Details on the page include parts lists, schematics and building details.

The are some pretty good SDR transceivers on this site.

Nice to get back in the radio chair agian.

Nice to get back on the air again
Just this morning I was looking over my last blog post and could not believe it was posted 3 weeks ago! I will say that things here at VE3WDM have been busy and it has not been with radio time. We had our Thanksgiving holiday last weekend and that weekend was packed with family things, shopping and making a turkey dinner. This year for the first time I tried cooking the turkey on the BBQ using the rotisserie, seems it turns out much better when the bird is done old style in the oven........live and learn. The other sliver of my time was taken up with work and once you factor in sleeping and eating not much time was left for radio. Last evening I pulled a 12 hour evening shift at work and arrived home this morning not feeling to bad so Julie and went out for a nice breakfast and then home to some well deserved radio time. The rig was tuned to 17m and I heard GI4DOH calling
GI4DOH
loud and clear  from Northern Ireland. I gave him some calls but was not heard but I did hang in there and finally my 5 watts made it to him. It was nice to get back on the radio as I find this to be a very relaxing time. I then jumped off 17m and over to 20m but there was a huge contest presence there (not that there is anything wrong with that I am a huge contest fan) so it was back up to 17m again. It seemed that for this afternoon Richard was going to be my only contact but it sure was nice to get back on the air again!

Para-saki all diode QRP transceiver

This looks like a design by Michael Rainey AA1TJ, but this one was on a German blog site of Peter DL3PB. I was very annoyed by the Facebook pop-up that kept appearing. I kept closing the pop-up but it is really annoying. Website owner – PLEASE get rid of it!

See http://streampowers.blogspot.co.uk/2013/08/para-saki-qrp-transceiver-fact-diodes.html .

The design makes extensive use of tunnel diodes, a Michael Rainey favourite.
