http://qrznow.com/th-d74-kenwood-aprs-d-star/ a cording to the bottom 72,800 yen or about $720 bucks.....and not a single word about their flagship skycommand.......if it turns out to have skycommand, I'll buy it imediately. It would be nice to scan the hf bands on the ht looking for dx, and...
With APRS and TNC capabilities with GPS, it seems like they are replacing the D72, But I have seen no mention of skycommand. Based on the current price of the D72, I am guessing this unit will cost $550
Hi Mole, I was wondering, what is the highest TX bandwidth? It looks like in the picture you posted that the audio scope goes out to 4k, But will the software allow to go to 4k or does it brick wall a 2.9 like most Icoms?
Also, have you tried AM?
Thanks
Hello, I have a nice SB 220 with two brand new matched Machlet 3-500zg's. I have done the following to the amplifier.
Direct grounded the Grids, New Harbach Soft Start, Harbach HV metering board, and replaced the capacitors with 500v, 390Mfd computer grade units. The bleeder resistor are now...
Ive gotten a couple questions, and probably should have mentioned this since I dont have pics up yet. The RCI is the last generation of the orange display models.

Hello, I am selling my MONSTER rci 2950. It has an RFX 75 and a built in 4 transistor(2879's) amplifier from a connex 4300-400wsm. There is a switch on the back so you can turn the amplifier off and run just the RFX75 at about 60 watts peak. Variable is set for a 30-100 watt carrier and peak...

Will you be able to post a vid with current draw, voltage and power meter measurements?
Also in your video you mentioned "with this technology" What are you doing that is different from other builders? Using pad on input to present a 50ohm resistive load? High quality input transformers?
PS...
Hi Shockwave,
NO, luckily this is the older Bipolar Version with 2166 Driver and 1969 final. The PA uses dual 2290s in push pull config.
I am shooting for 50 watts as long as I dont exceed the current rating on the transistors and the radio does not get too hot. If I can not reach 50 watts...
Alot of views but no comments. Ill give it a try and report back on performance. Ill do a before and after on the specan to see what the IMD and Out of Band Distortion are.
I would like to see a DC current meter, voltage meter and power meter all in one shot. That will be the true test of linearity and performance. A Spectrum analyzer shot out to the 5th would be nice as well.
