Absolutely true, but you have to wonder about the modern day "motor heads" who are tweaking these modules for various "performance" goals. You can bet they see some bugs from time to time. But then t

Very well stated. Also consider that there are two different levels of code writing involved here. One is control software and the other is the low-level DSP code. The control code for the computer c

There is actually a wide variety of different grease types used throughout agriculture, some of it is totally worthless for this application and would gum up the VFO from the start. So if you do go t

Yupp, and it doesn't hurt to wildly speculate and pontificate every now and then either ;). I find that of all the brand specific reflectors this is one of the more interesting and entertaining ones.

If you are going to be using a Jupiter as an IF radio it would be reasonable to expect similar overall performance to the 526 since they share a certain amount of similarity. The main difference betw

Consider a transverter for 2M. That will give me another easy to work 2M station from EN53 :). Seriously though it would give you a real good sense of how a transverter will work without duplicating

I wouldn't get too wrapped with having all bands in one box. If you are serious about VHF/UHF weak signal work you want mono-band radios for each of the bands anyhow. There is also good reason to hav

The 20W of the 526 will drive the typical 6M brick fine, probably even need to back off the drive a bit. An Astron RS-35 or SS-30 series power supply will handle such an amplifier handily. While thi

It is fixed at 57,600. The main advantage of a Jupiter over a Pegasus is that you do have more versatility by virtue of having traditional controls AND 100% computer control. While RS232 ports may go

However if you accept the notion that a "Software Defined Radio" can never be truly complete, then "incomplete" software in and of itself is not a problem. The basic assumption is that as a designer
