R4B 80m not working


 

Good morning.

Late night in the shack and was listening to the bands with the B-line twins. Everything is working well with exception of the R4B on 80m.

Generally I run the twins with the proper injections cable with the T4XB setting of XVCR driving the injection to the R4B. All bands working correctly (including 80m) and providing proper output to the frequency counter as well.

When running the R4B as separate, RCVR, and also with the T4XB turned off, I get nothing on 80m. For 40m and all other bands, the preselector peaks the signal, proper frequency shows on the counter, and everything else works.

On 80m, with the R4B as master or separate I am not receiving signal, preselector doesn't affect peaks, and no output to the frequency counter. Also if I move the preselector close to 12 o'clock it will start to pickup signal close to the WWV 5Mhz but it doesn't align with the VFO dial.

Before I pop the hood, any thoughts? Before I got the T4XB I used this R4B with another TX. Was working fine at that time, and I haven't been doing anything inside the case since then.

Thank you for any thoughts, if you need any other information please let me know.

Thank you
