We have a KPA500 in our station setup of HU1DL.

After some days of operation (and changing of bands, filters, antennas),
the T/R pin diodes are blown (D8/ D9).

- amplificaton of the RF-input signal works well

- receive level/ noise level in standby is normal

- receive level/ noise level in operate mode in attenuated

Now we are looking for a replacement.

- which type (hope we can buy pin diodes in San Salvador)

- howto change D8/D9 in the KPA500

We also send an email to ELECRAFt support, waiting for response.
