The 67% increase is cheaper than air mail.

Your carl built Is biased I would be willing to bet. I have noticed this issue with several 2879c biased amplifers. They like some antenna systems and not others.

Perhaps we should disable the swr protection and do a few tests. I often forget to switch my bench radio back to antenna that is where I run my Washington.

I have a sigma 5/8 venom up for about 3 years in the Oklahoma wind, good antennas. I imported a few and quite a few locals are running them in this area.

Now if we had something like a switchable channel guard crystal filter that would be a good use for that switch. The Gnf just sounds bad.

I have been looking in to the qh40a crystal heaters, they use them on drifty ham radios.

On the new President Washington the 2 Irf 520 finals run at 19 volts and are capable of 100 watts clean on the spectrum analyzer. Were there ever any BI-polar transistor in the same package that were capable of this?

I got started in the mosfet world, I like them personally you get good power with low amp draw and if bias is set properly they are plenty durable.

I kinda hope the stock ones are better. It is easier to leave a part in than it is to change it.

The next project will be a tx rx interface for my old Dx 2517 at the house. I am also looking to try js8call digital mode when I get everything set up. Signalink usb would probably be the simplest solution but I think I can use this device available for much less at...

27.700 usb international also 27.660 Europe and 27.680 north America. I have a big noise floor here at work so I am excited to try it at home this weekend.

I have been doing some research in to slow scan tv ever since a friend told me about activity on 11 meters at the Queen Wilhemena ham fest earlier this month. Today I made a simple 3.5mm to 3.5mm audio cable and plugged it in to the Ic-7300's headphone port, the other end plugs into the...

I know you have a big mobile @linearone What are you running?

That DIrland looks just like the superstar 121 I have in the wife's car, with npc-rc and a ranger echo board that thing makes a good little bull hauler radio.

With hq-27s smokey wont have a chance.

It would be nice to have a base box built in another black rack mount case to match it.

It may offend some but I would take a 2547 over a Cobra 2000. Its a lot easier to get them clean and loud. Extra channels with just 2 switches.

Put that thing on an 8719 Washington with a super slider.

I really like these, even with all the new radios on the market I think my next mobile will be the Alinco dx-10, they are tuned for a dynamic mic unlike the Lincoln 2+. Basically a 447 with ssb.
