Did you know your IC-2820 should have the ability to cross-band repeat on D-Star, making it a simple HotSpot?

Did you know your IC-2820 should have the ability to cross-band repeat on D-Star, making it a simple HotSpot? There is a UHF D-Star repeater some 20 miles away. My home is below the crest of a hill, so I erected an antenna in my attic. I cross-band repeat to VHF and I am able to chat using my IC-V82. Here is how you set it up:
First Step on the 2820:

Hit the function (F) button twice to take you to the DV menu.

Hit the Menu Button on the Right side of the rig.

Scroll to the DV Set Mode and press the lower round knob on the bottom left

Scroll down to the Digital Monitor entry, and make certain it is set to "AUTO"
Second Step:

Dial in the desired VHF frequency (of your repeater or your desired crossband frequency) and set the mode to FM (Not DV, nor FM-N!). Set the offset (DUP+ or DUP-)

On the right side, set your frequency to the UHF frequency (of your desired crossband frequency, or your repeater). Make sure you set the appropriate Duplex mode (DUP+ or DUP-)

Also make certain to set the mode to FM.
Last Step:

This can be a bit tricky until you get the hang of it. To start crossband mode, press the two main tuning knobs and the function button (F) simultaneously. If you did it correctly, the lock symbol on the right side of the display will flash. Make certain the squelch is "just at" the closed setting with no signal present.
On your Handheld:

Set the VHF frequency if you are crossbanding to UHF, or visa versa. Also set DV mode. Make certain to enter the opposite offset duplex that you set on the 2820. Set all other settings as if you were connecting directly to the repeater. I recommend you store these entries into memory.

That's it!

EasyPal

EasyPal software was created by Eric VK4AES, use DRM (Digital Radio Mondiale) encoding to allow the sending of images via HF or VHF using only 2.5kHz (like voice) This is known as Digital SSTV.'s DRM Easypal used, allowing very fast data transmission with error correction, requesting missing blocks, allowing highly accurate decoding. images up to 1280x1024 is sent in a little over 1 minute, Easypal compresses images to reduce transmission times. In the city of Rosario in the frequency 144.980Mhz a group of ham radio enthusiasts are often found to test different digital modes, including EasyPal. Everyone is invited to participate in the broadcasts, Best Regards.

More Demos of PSK-31 and Ham Radio Deluxe and DM-780 Program from KI7F

**** RE-EDITED VERSION ****
Just some more video footage of my amateur (Ham) radio/SWL "shack" at my apartment in Denver, Colorado. I was demonstrating some of the features of the Ham Radio Deluxe (HRD) software program as well as the Digital Master780 software which integrates with the HRD program. I also showed the PSK Reporter map and how the PSK-31 stations I receive are plotted on a world map on the PSK-Reporter website, etc. You can view the PSK Reporter map at http://pskreporter.info/pskmap.html

The Grundig Satellit 800 receiver I am currently using is essentially a repackaged Drake R8 receiver.

I am planning to purchase a Yaesu FT-950 HF rig in just a few months and also plan to use the Rig Blaster unit for interfacing the rig with the computer, etc. I do plan to operate PSK-31 or course as well as CW and SSB. With indoor antennas, I may be forced to operate at QRP power levels. At the moment I can operate on the ten meter band with my old Realistic HTX-100 ten meter rig and using a ten meter dipole installed on my apartment balcony.
