Looks like a contest weekend for sure!

In other words, you are saying I wasn't wrong I was just mistaken. That's funny! I never said I was a Yaesu fan just the fact the Yaesu higher end radio's went with a hybrid super het/hybrid combining the best of both worlds. 73 GL on channel 38

Key word "considered". The manufacture can advertise it as they want. There is a big difference in features between the 718 and 7300 as you know. The 718 is a fairly bare bones radio with a simple layout and marketed for ease of operations and it has been around for many years. Many CBers on...

Sorry sir, but you just contradicted yourself after you found out you were incorrect. Look what you previously said about the high end Icom direct sampled SDR's having roofing filters. After I posted that they do not have them, now you say the current models don't because they are unnecessary...

No they don't, we are tallking SDR models like 7300, 7610, and the new flagship model 7760. They all use Digi-select digital filtering which is not a roofing filter by design. On a crowded band it's already been known that a SDR direct sampling radio can overload and a weak signal on the band...

Just the opposite for me, I don't care for touchscreens at all. Just puts greasy finger prints all over the screen. I just like having a bigger display screen.

My Kenwood TS890 uses DVI too. I thought the same thing about manufactures using DVI for external display but I found out the reason why. HDMI is a proprietary brand name and requires a licensing fee for every electronic device to use it and Yaseu and Kenwood and the other Icom's apparently...

There are NO traditional roofing filters on full SDR radio's like the Icom 7300 including the new MK2 version and Yaesu FTDX710. They use digital processing filters to try and mimic similar results. True roofing filters are found on mid price range level to high end superhet and hybrid...

So this proves what I read about having an all SDR receiver. I once played around with an SDRPlay and had some overload issues. From what I understand about SDR receivers is a single FPGA is sampling an entire band and the more signals on that band especially on a contest weekend like the one...

Ok, so how do you control front end overlaoverload on a crowded band like 20m on a contest weekend? This is the known pitfalls of direct sampling receivers and not a problem with superhet.

Yet Icom is still relying on all direct sampling RX where Yaesu uses a hybrid with a super-het front end in front of direct sampling on the FT101 and FT10. Elecraft is still working on the KX4 HD Hybrid. The hybrid is better on a crowded band where an all SDR will be subject to front end overload.

That is a nice amp and they are well built and known to reliable. I'm sure if you wanted to sell it, somebody would like to have it.

I have the Tokyo HP HL-450B amplifier which is capable of 100% duty cycles on modes like AM, FM, RTTY etc with up to 40 watts drive but the manufacture recommends reducing drive about 20% on those modes. Your amp is capable of the same but can take up to 80 watts drive on SSB but it is...

Full quarter wave whips are the gold standard but not always pratical for some mobile installs. A Wilson 2000 will work just fine but that are almost as expensive. The obvious advantage to them is manageable height and fine tuning. The losses in the coil on the Wilson is insignificant to the...

Those whip get shipped as oversized so where ever you buy them online oversized shipping is included in the price or billed separately. $78 sounds about right. DX Engineering sells the whip for $42 but add $39.99 for oversized shipping and it's $82 Remember when Ratshack sold them, the last...
