Well, I think I have my station about ready to go now. First time in a few years that I have sat down to play on the air. It's nice to see all this working. Now I just have to get used to the program again then explore the other digital modes and programs.

From my location in Nampa, Idaho, USA I was able to read Cuba, Dominican Republic, Ontario, Canada, BC, Canada, Wisconsin, Indiana, Texas, Arizona, California, Kentucky, New York, and several other US stations with this setup today so I'm quite pleased with it. 20m, of course.

This week on Amateur Radio Roundtable, Rich Richard Moseson W2VU editor of CQ magazine will be giving us a look into next month's issue. Katie Allen WY7YL will also be talking to Robert Greenberg, W2CYK the developer of the Worldwide Repeater Directory and RFinder. We have a couple prizes this week. We will also have your shack pictures and a bonus segment showing what others are using for their BITX40 transceiver cases. The sky is the limit, you will see plastic boxes, pie pans, repurposed switch boxes, plexiglass, lunch boxes and much more. Phone lines and chat room are open for our viewers. You can watch the show at W5KUB.COM at 8:00 PM Central time every Tues. This program is also simulcast on famous international shortwave station WBCQ on 5130 Khz. (for international viewers the time is 0200 UTC Wed)

Hello operators.
Today I'm sharing an introduction to the latest kit from Super Antenna called the MP1DXMAX. The MP1DXMAX is an ultra portable HF/VHF antenna system with an incredibly small break down size, and rapid deployment.

The video covers:
- What's included in the kit.
- Setup and configuration.
- Performance testing.
- Pros and Cons.

This is a more advanced, albeit not yet definitive, setup of my mobile.

Initially I used an icom F110 programmed for ham usage, but quickly removed because of the strong qrm issues (and anyway, the F110 can be better for packet at home). The rtx is now an yaesu FT-2900. The advantage is that it fits quite nicely in place of the glove box: I just had to file a bit the plastic of the hole on the corners. There are two gaps on the side, but then, since there isn't any forced ventilation, they play my game: ventilation. On the top of the dashboard, a remote speaker.

The power supply is not yet directly from the battery (dashboard/airbag complications), and it's taken from the cigarette socket. I can't run the radio full power and, even if behind the rtx I installed a power line filter, I also wound the cigarette plug cable on a springlock, in guise of a choke inductor.

The antenna is on the roof, about 1/4 from the front. I chose this place for two main reasons: I can easily access there from the overhead console and route the cable down from the door jamb to the central console, and the antenna there doesn't interfere with the rooftop box or with the bicycle rack.

The horrible qrm found at the beginning, still with the icom (but also with the yaesu), so strong that muting it was like putting the squelch to 80-90%, was caused by a little switching power supply for a dashcam, installed by the previous owner. It sounded like an hiss of white noise. Waiting to modify it for making rf silent, it was removed.

Without the switching module qrm was better, but still at 50-60% of squelch. With engine off, it dropped to 20% squelch. Tx is not a problem, even driving on the highway the signal is strong and clear.

I decided to shield a bit the cables, and for every sensible area I applied aluminium foil. Not the best solution, probably, but it helps. Now with engine revving I can turn squelch down to 40% before opening the frequency. Not yet the best, and I believe I can still do a couple of things: Power directly from the battery, and better shielding of the antenna cable (perhaps with a lead plate) or tin plate.

Thanks to +Ed Liddle+Graham Merrill+Andrew Westman​ for providing me insight of a mobile installation qrm related

I have finally gotten HDSDR running as a pan adapter on my Yaesu FT-1000MP Mark V without having to do a internal IF tap in the radio thanks to NC4WS Wayne. I ask him what was inside the "magic box" he shipped to me and this was his reply:

Inside the box is an RF upconverter made by NooElec--can get them on Ebay. The circuit I built is a splitter. I got the details and schematic diagram from Clifton Laboratories which is no longer in business. It is a splitter called Z10050A3-DB. The upconverter uses a 125 MHz crystal oscillator that mixes the antenna input and gets the signal above the FM band and inputs this IF into the RTL2832U+R820T dongle (also available on Ebay and Amazon) which receives signals above 24mhz. The input to the upconverter is wired inside the box from the splitter. The splitter has three inputs or you can say it has two inputs and one output---which is fed to the input of the upconverter board. The other two inputs to the splitter comes from the receive antenna IN and OUT RCA jacks from the rear of the radio. The reason we use these inputs is because when you transmit the radio grounds the receive antenna through a relay so you do not feed a high rf signal into the upconverter and burn it up. That is the best description I can give. If your radio does not have the IN and OUT like Yaesu, then you will need a splitter like the MFJ-1708 that senses RF and a relay grounds the input.

Anyway, the thing works great! I could have went the route of doing the IF tap inside the radio using the G4HUP buffer board, but was reluctant about messing around inside my Mark V because it has a microprocessor I was afraid I may damage just from static electricity on me. I definitely would want to wear a wrist grounding strap if I ever do mess with anything inside the radio, but to me this was a much easier and safer route to go. Very 73 de KU4GW

Thanks to URE and all supporting people around for nice event last week. The bands were full of nice pileups and activities again. Perfect!

It has been a while ago but still this is my most memorable contact on the 6m band. It is my only transatlantic QSO till today on this band. And absolutely a almost unbeatable QRP record as well for 50MHz (at least for me!)
