私が欲しいトランシーバは、

このところ各社からいくつか新しいトランシーバが出ていますが、どうも私が飛びつきたくなる機種が見当たりません。やっぱりスペクトラムスコープは「目玉」なんでしょうね

私の条件は、
・ 高価な機種は買えないので、中クラス以下
・ 100W又は200W、可能なら自動ATU内蔵
・ スペクトラムスコープは不要
・ 2波同時受信が出来ること KX3のように最大15KHzという制限があっても、ある/無しでは雲泥の差
・ 小型、軽量、電源は外付けで可

私が今持っているのは、
・ K3/100 イチバン不愉快なのはボタンの誤動作
・ K2/100 2波同時受信さえできれば今でも十分使える、ボタンの誤動作もない
・ TS590SG 2波同時受信さえできればベスト、安いし
・ FT1000MP なにしろ古くて、どこか壊れたらおしまい
・ KX3 10W、家で使うにはアンプが必要   移動用
・ IC7000 このクラスで自動ATU、2波同時受信ができれば家でも使える  移動用

Huntsville Hamfest 2016

Linda and I attended the Huntsville Hamfest and met up with our friends John W8JER and Micky KE8ASK. They drove down from Sturgis, Michigan and we drove up from Panama City, Florida. I gave a presentation for the National Parks On The Air Forum at Noon on Saturday. It went well. I had a mixture of slides and videos. One video, about the Naval Live Oaks Biodiversity Festival, was made and narrated by Bob KK4DIV. There were some activators in the audience that chimed in. I would not have made it through without my buddy John K4KQZ from Tennessee who helped kickoff the videos at the laptop.

The four of us attended the gathering on Monte Sano on Saturday night hosted by Craig NM4T. There was delicious BBQ and lots of conversation. The show and tell included fldigi running on a Raspberry Pi 3 and the new LNR magnetic loop. I showed my Elecraft KX2.

At the show, I picked up another Jardillier French Made Special Forces Key. Those are hard to find. I think Neil the vendor there is the only one that has them for sale. I also got a MFJ 40 meter loaded whip for the KX2 and mini-banana plugs that fit the counterpoise connection. Linda out spent me on jewelry. Well that's OK.

I had some drama with my Chevy Avalanche. It had a terrible squeak. Fortunately I visited Russell Brothers Repair Shop before leaving town. The mechanic there narrowed it down to a lifter. His advice was to add Marvel's Mystery Oil. This eliminated the problem by the time I was halfway back to Panama City.

Linda and I enjoyed the fellowship with John and Micky and look forward to their stay in Panama City this winter. John has a new Subaru that practically drives itself. My only photo from the hamfest was this one that Micky took.




Happy Anniversary, Voyager 2 !

Thirty-five years ago today, a NASA spacecraft got an up-close look at beautiful, enigmatic Saturn. On Aug. 25, 1981, the Voyager 2 probe zoomed within 26,000 miles (41,000 kilometers) of the ringed planet’s cloud tops. The discoveries made by Voyager 2 — and by its twin, Voyager 1, which had flown past Saturn nine months […]

CY9C – St. Paul Island DXpedition – via Satellite

I was fortunate enough to work CY9C today at 21:08:39 during a pass of AO-7.  Great operator on the other end and great signals too.  Heard him work quite a few prior to me as well.

This years summer holiday has been excellent as I enjoyed lots of family time at our holiday shack and also plenty of Van Camping in the DX Machine. I also managed some great ham radio contacts and got my Cushcraft Beam up at my QTH  which has made a big difference for me, its working well! Its come around quick as I am back to work next Tuesday but I have certainly made the most of my time off. The family have had a great time and we still have the bank holiday weekend to enjoy.

Best 73 and here are my latest contacts followed by some pictures I caught out and about on the Welsh Island of Anglesey and also the East Yorkshire coast during my summer tour.

REVIEW: IF tap adds bandscope to FT-450D

I installed the  HupRF PAT IF tap by G4HUP on my Yaesu FT-450D a few nights ago. The G4HUP website describes the PAT as a “small circuit board which can provide a high impedance tap of the IF of your rig, so that you can connect an external SDR to improve your operating experience. PAT is powered from the RxB line within the rig, so it is self contained and self-muting on Tx, which prevents high level Tx signals being passed to your SDR.”

I’m super pleased with the performance so far. It was a little fussy to install the SMA adapter on the back of the radio, and involved taking it apart further than I would have liked, but… I got it done, and it looks pretty decent.

Here’s the port I installed on the back of the rig:

ft450d-tap

Here’s the board installed in the rig:

hack-soldering-job

It’s kind of a touchy soldering job. Working with RG-178 is a real pain.

My SDRPlay RSP has a full view of the antenna. The signal seems to be just a little attenuated (-2dB) vs the receiver on the FT-450D. I ran two copies of WSJT-X and compared decodes to come to that conclusion. More testing will be required.

I have a lot of control over the gain and sampling rate on the RSP, so there’s a lot to fiddle with to get it operating somewhat optimally. The RSP still sees my transmitted signal, but at around -60dB. No where near strong enough to desensitize the receiver.

Here’s a screenshot of SDR Console V3 preview from my RSP through the FT-450D:

The tap plus RSP allows me to run multiple receivers on up to 8MHz of total bandwidth. The sweet spot performance wise is 2MHz. This setup allows me to pipe digital modes (I prefer JT65 and JT9) audio from one receiver on the RSP to wsjt-x, and add a second receiver, monitoring a sideband station output to speakers, and a third receiver monitoring a CW QSO, output to headphones. The number of receivers seems to be only limited by the computer’s resources.

I really enjoy this modification. Considering how inexpensive the board was, and the relative ease installing it… I think this might be the biggest bang for the buck in my shack!

IARU Region 1 Emergency Communications Coordinator Greg Mossop, G0DUB, has requested that 7060 kHz (LSB ±10 kHz) be kept clear of non-emergency traffic, as well as any other center-of-activity (COA) frequencies that may be in use for emergency communication within Italy. (On 80 meters, the COA frequency is 3760 kHz). Other frequencies reported to be active include 7045, 3643, and 3580 kHz (PSK).

Louisiana Amateur Radio Emergency Service Volunteers Stand Down:

Amateur Radio Emergency Service (ARES) volunteers responding to the Louisiana flood emergency stood down on August 20. Assistant Section Manager Matt Anderson, KD5KNZ, reported over the weekend that Louisiana ARES was in the process of deactivating from the recent flood response, and that there was no longer a need for additional volunteers. Anderson served as the Incident Point of Contact in Baton Rouge.

Low storm risk

According to my maps, the nearest lightning is off the coast of Yorkshire and in the Bay of Biscay, so no risk hereabouts at present. I'll stay on 10m JT65 for now but keep an eye on the storm map, ready to disconnect things if the need should arise.
