Re: [Elecraft] Heil HC-5 Taiwanese Equivalent?

[Fernando Sindeaux via Elecraft]

Dear Tony,
I also use an original Heil HC-5 with my KX3 and K3, with the best audio report 
I ever had received.
Unfortunately is a little hard to find one nowadays. And when someone offer 
one, ask an abusive price, $100.00! Just for the element!!!
Beware of the new version HC-5.1! It’s very bad audio and output level as 
well. Just read some comments and reviews!
Best regards,
Fernando, PY1BL

Re: [Elecraft] Oscilloscope recs

[Fernando Sindeaux via Elecraft]

Dear Friends,
I recently purchased a Hantek 4102C, 100Mhz, dual trace and have a signal 
generator as a bonus! Plenty of nice features on this scope, at an affordable 
price $274.00.
I’m very satisfied, meet all my needs. I highly recommend this nice scope.
Best regards to all,
Fernando Sindeaux, PY1BL
